Rakuten Group, a global leader in internet services, operates a famously diverse ecosystem spanning e-commerce, fintech, digital content, and mobile communications. What's perhaps less visible is how this sprawling network of over 70 businesses serves as an immense internal proving ground. Rakuten doesn't just build technology for its customers and partners; it is, in many respects, its own most demanding first user. This deep internal adoption, particularly evident in its aggressive push into Artificial Intelligence and its revolutionary approach to mobile networks, is a core driver of its innovation and shapes the very products and services it offers worldwide.

### "Rakuten AI for Rakutenians": Empowering from Within

One of the most striking examples of Rakuten "eating its own dogfood" is the **"Rakuten AI for Rakutenians"** initiative. This isn't a niche tool for a few engineers; it's a suite of AI capabilities used by an overwhelming majority of Rakuten's global workforce—reportedly 30,000 employees, with 8,000 using it daily. As detailed on the [Rakuten Today blog](https://rakuten.today/blog/inside-rakuten-ai-shaimay-shah-on-driving-rakutens-ai-transformation.html), this internal AI platform helps automate routine tasks like summarizing meetings, chats, and emails, and even assists non-technical employees in creating custom AI applications without coding expertise.

Shaimay Shah, a data scientist in Rakuten Group's AI & Data Division, encapsulated the philosophy: **"The goal for Rakuten AI for Rakutenians stems from the fact that to empower others, we must first empower ourselves.”** By making its own diverse workforce the first beneficiaries and testers of its AI tools, Rakuten achieves several critical outcomes:

* **Rapid Iteration and Refinement:** Direct, widespread internal use provides immediate feedback, allowing for quick identification of bugs, usability issues, and areas for improvement in their AI models and interfaces.
* **Democratization of AI:** Enabling non-technical employees to build their own AI tools fosters a company-wide AI literacy and culture of innovation. This also means that AI solutions are being tested against a vast array of real-world internal use cases.
* **Robust and User-Friendly Solutions:** Before similar AI capabilities are offered to external business clients (like the "Rakuten AI for Business" generative AI service), they have been battle-tested and validated by tens of thousands of internal users.
* **Efficiency Gains:** CEO Hiroshi Mikitani has highlighted the significant productivity and efficiency gains achieved through this internal AI adoption, with a stated goal to boost marketing, operational, and client efficiency by 20% using AI. (Source: [Rakuten Today](https://rakuten.today/blog/supercharging-rakutens-merchants-with-ai-ceo-mikitani.html))

Rakuten's strategy involves developing its own specialized AI models, like Rakuten AI 7B and Rakuten AI 2.0, optimized for specific needs such as the Japanese language. Mikitani emphasized, "The key lies in how much effective information you can connect – that's why we needed to do it ourselves.” This internal development and deployment cycle for AI is a powerful form of "dogfooding."

### Rakuten Mobile as Customer Zero for Rakuten Symphony

Perhaps the most ambitious and impactful example of Rakuten using itself as "customer zero" is the journey of **Rakuten Mobile** and the subsequent birth of **Rakuten Symphony**. Rakuten Mobile famously built the world's first fully virtualized, cloud-native Open RAN mobile network in Japan. This was a monumental undertaking, challenging traditional telecom infrastructure paradigms.

The experience, technological innovations, operational expertise, and software developed in deploying and running Rakuten Mobile now form the core offerings of Rakuten Symphony, which provides these cloud-native telecom solutions to operators globally. As detailed on the [Rakuten Symphony blog](https://symphony.rakuten.com/blog/ten-telecom-realities-to-guide-2025-planning), Rakuten's experience as an operator provides a unique perspective and a battle-tested platform. They didn't just theorize about a new way to build mobile networks; they built one for themselves, facing and overcoming the real-world challenges involved. This makes Rakuten Symphony's offerings inherently "dogfooded" at an unprecedented scale. The collaboration with partners like [Red Hat](https://www.redhat.com/en/about/press-releases/red-hat-provide-rakuten-mobile-and-rakuten-symphony-open-source-expertise-and-solutions-innovate-and-enhance-customer-experience) and [Dell Technologies](https://www.dell.com/en-us/blog/unlocking-the-telecom-cloud-with-dell-and-rakuten-s-blueprint/) further underscores the development and validation of this telecom blueprint.

### "SixthSense": Observing Their Own Universe

To manage its vast and diverse digital ecosystem, Rakuten developed an internal AIOps platform called **"SixthSense."** This platform, as described by [Techcircle.in](https://www.techcircle.in/2025/04/11/rakuten-s-india-gcc-moves-beyond-support-builds-ai-platforms-for-global-ops/), monitors all of Rakuten's digital systems in real-time, using AI for anomaly detection and root cause analysis across the full stack—from infrastructure and data centers to applications and user experience.

By being its own most critical user of SixthSense, Rakuten ensures the platform is capable of handling the scale and complexity of a global internet services company. The insights gained from monitoring their own e-commerce (Rakuten Ichiba), fintech (Rakuten Card, Rakuten Bank), and mobile operations feed directly into the refinement of SixthSense, making it a more powerful tool for maintaining stability and efficiency across the Rakuten ecosystem.

### The Rakuten Ecosystem: An Interconnected Proving Ground

The power of the Rakuten Ecosystem lies in its interconnectedness, with Rakuten Points serving as a unifying loyalty program. While less explicitly detailed in terms of direct product development feedback loops for each consumer service, the sheer number of Rakuten employees living within this ecosystem provides an ongoing, organic testbed. Employees shopping on Rakuten Ichiba, using Rakuten Card for payments, booking trips via Rakuten Travel, or streaming content are constantly interacting with the company's core offerings.

This internal user base, familiar with the desired "Rakuten experience," can offer valuable qualitative feedback on usability, new features, and the seamlessness of cross-service integration. Rakuten's focus on analyzing vast amounts of customer data with AI to personalize experiences and improve services (as mentioned by [Rakuten Today](https://product-conference.corp.rakuten.co.in/blog/Rakuten's-AI-Revolution-Shaping-the-Future-of-Business-Technology-and-customer-use-cases)) would undoubtedly benefit from the data and behaviors of its own engaged workforce.

### Conclusion: Innovation Through Self-Reliance and Ecosystem Synergy

Rakuten's strategy of deeply integrating its own technological solutions into its diverse operations is a powerful form of "dogfooding" that extends beyond simple product testing. It's about building foundational platforms—be it for AI-driven productivity, cloud-native mobile networks, or full-stack observability—to meet its own complex needs first. This internal proving ground, populated by tens of thousands of employees and spanning a multitude of business domains, ensures that when Rakuten offers these technologies and services to the world, they are not just innovative but also robust, scalable, and validated by real-world, high-stakes deployment. By "empowering themselves first," Rakuten is truly building the future of its ecosystem from the inside out.

Rakuten's Ecosystem Within: How Internal Innovation and Use Power a Global Tech Giant


Airtable has a bold mission: to democratize software creation, enabling anyone to build the custom applications they need to power their work, regardless of technical skill. This vision of empowerment isn't just an external mantra; it's a deeply ingrained practice within the company itself. Airtable employees, across all departments, are avid users and builders on their own platform. This extensive internal adoption—a true "Airtable on Airtable" approach—is fundamental to how they innovate, refine their product, and ensure it genuinely meets the diverse needs of its global user base.

### The Ultimate Proving Ground: Running a Company on Airtable

From product operations and marketing campaign management to HR workflows and sales CRM, Airtable teams rely on their own platform to build and manage their most critical business processes. This isn't just about using a few shared bases; it's about employees at all levels creating custom applications, interfaces, and automations to solve their unique challenges and streamline their day-to-day tasks.

Howie Liu, Airtable's co-founder and CEO, has emphasized the vision of creating a "radically faster and more intuitive way to build useful applications." (Source: [Airtable About Us](https://www.airtable.com/about)). This vision is constantly tested and validated by its own workforce. When an internal marketing team builds an Airtable app to manage a complex content calendar, or when the product team uses it to track feature roadmaps and user feedback, they are experiencing the platform exactly as a customer would. They encounter the same potential friction points and moments of delight, providing an invaluable, real-time feedback loop.

### AI Transformation: Starting From Within

Airtable's recent push into AI capabilities is a prime example of its internal-first approach. Before rolling out Airtable AI and tools like **Airtable Cobuilder** (which allows users to create apps in seconds using AI) to the public, these technologies were extensively used and refined internally.

In a [Salesforce Ventures interview](https://salesforceventures.com/perspectives/platform-evolution-in-the-ai-era-insights-from-airtable-ceo-howie-liu/), Howie Liu discussed "Starting AI Transformations From Within The Company." This involved internal hackathons where teams reimagined their work with AI and the appointment of "AI ambassadors" across departments to champion its use. Liu noted, "By definition, it's this flexible data schema that every customer can define their own business objects on top of... Every company decides their own use case." This flexibility is tested and proven by Airtable's own teams before it's expected of customers.

The aim, as highlighted in Airtable's [product development report](https://downloads.ctfassets.net/wl95ljfippl8/4akiSr2HsHSPWGIM0eJG1E/378f0d0c3d88b9d37f0eac86eafa56ea/2025_Airtable_Predictions_-_Product_in_the_era_of_AI.pdf), is to "infuse AI into their internal operation [and] deliver AI experiences into their products." When employees use Airtable AI to categorize customer feedback, generate product specs, summarize data, or even draft blog posts (as marketing teams might), they are directly contributing to the refinement of these AI features. Their successes and challenges inform the development of more intuitive prompting, more accurate outputs, and more useful AI-driven suggestions for all users. Some [user experiences shared on community forums](https://community.latenode.com/t/experiences-with-airtables-artificial-intelligence-features/14407) echo the kinds of productivity gains and learning curves internal teams would also navigate.

### How Internal Builders Shape a Better Platform

This deep "dogfooding" culture yields numerous benefits that directly impact the quality and usability of the Airtable platform:

* **User-Centric Design:** Because employees from diverse roles (not just engineers) are building apps, the platform is continuously evaluated for its ease of use by both technical and non-technical users. This fosters empathy and drives the development of truly intuitive interfaces and building blocks. The [Airtable Engineering Culture on Key Values](https://www.keyvalues.com/airtable) emphasizes "Bonded by Love for Product" and "Start-to-Finish Ownership," mindsets that thrive when using the product daily.
* **Rapid Identification of Pain Points:** If an internal team struggles to link records in a complex way, set up a nuanced automation, or design a clear interface for their specific needs, these pain points are immediately visible and can be addressed by the product and engineering teams.
* **Real-World Workflow Validation:** Airtable isn't just tested in hypothetical scenarios. It's used to manage real deadlines, track actual budgets, and collaborate on critical company initiatives. This ensures that features like **Views** (Grid, Calendar, Kanban, Gallery, Timeline, Gantt), **Automations**, and **Interface Designer** are robust and practical for a multitude of real-world applications (Source: [Airtable Platform Overview](https://www.airtable.com/platform), [Airtable Support Docs](https://support.airtable.com/docs/introduction-to-airtable-basics)).
* **Driving Feature Innovation:** Many of Airtable's powerful features, from its diverse field types to its integration capabilities and its ever-expanding library of extensions, are likely born out of needs first identified by internal teams pushing the limits of what they can build for their own operations.
* **Ensuring Scalability and Reliability:** As Airtable the company grows, so does the complexity of its internal operations. Using its own platform to manage this increasing scale provides crucial insights into performance, data capacity (with features like HyperDB aiming for 100M+ records, as mentioned on their [Project Management page](https://www.airtable.com/solutions/project-management)), and governance needs, ensuring the platform can support large enterprise customers.

### The "Builder" Culture Extends Inward

Airtable's leadership team often includes individuals who were power users and advocates of the platform even before joining the company. Anthony Maggio, Head of Product Management, is one such example (Source: [Airtable About Us](https://www.airtable.com/about)). This creates a virtuous cycle where those steering the product's direction have a profound, hands-on understanding of its strengths and potential.

The general benefits of "dogfooding," such as improved product quality, faster feedback cycles, and internal buy-in (as outlined by sources like [HeroCoders](https://www.herocoders.com/blog/dogfooding-in-software-development-eat-your-own-code) and [Mad Devs](https://maddevs.io/blog/dogfooding/)), are amplified in a company like Airtable, where the product itself is a tool for creation and operational management.

### Conclusion: Empowering Others by Empowering Themselves

Airtable's commitment to being its own most active and innovative user is a powerful strategy. By building and running their company on the same platform they offer to the world, they gain unparalleled insights into the needs of modern teams and the evolving landscape of work. This "Airtable on Airtable" approach ensures that every new feature, every UI refinement, and every AI-powered capability is not just theoretically sound but practically proven. It’s this deep, internal proving ground that allows Airtable to confidently empower its customers to build their own "next-gen apps" and transform their operations from the inside out—just as Airtable itself continues to do.

Building the Builder: How Airtable Uses Its Own Platform to Empower Everyone

## **From Within: How YouTube's Own Tech Drives Its Global Platform**

In the fast-paced world of software, there's a common, yet often unspoken, practice where companies become the first and most critical users of their own solutions. This isn't just about quality assurance; it's a deep-seated philosophy of building better products by living with them day in and day out. YouTube, a platform that serves billions of hours of video to a global audience, is a prime example of how leveraging proprietary and in-house technology shapes a service's evolution, capabilities, and user experience.

This approach of turning inward for technological solutions allows companies to rigorously test, refine, and innovate on their offerings in a real-world, high-stakes environment. For YouTube, this means relying on and developing powerful internal systems to manage its immense scale and deliver a seamless experience.

### **Building on a Foundation of Internal Innovation**

One of the core strengths of YouTube is its ability to scale and manage a colossal amount of data and traffic. This is significantly powered by Google's own infrastructure. For instance, Google Cloud Bigtable is extensively used by YouTube. As described on the [Google Cloud Blog](https://cloud.google.com/blog/products/databases/youtube-runs-on-bigtable), Bigtable underpins a wide array of YouTube's functions, "from helping connect people with new content based on what they've watched, to recording metrics like view counts to powering advertising functionality." The YouTube Data Warehouse, crucial for analytics and insights for creators, is also built on Bigtable, demonstrating a deep reliance on this internal NoSQL database service for handling massive datasets and enabling features like Creator Analytics.

Furthermore, while YouTube initially used third-party Content Delivery Networks (CDNs), it eventually transitioned to building its own proprietary CDN. This move, detailed by [Intuji](https://intuji.com/how-does-youtube-work/), was driven by the need "to manage scalability and cost-savings," a classic example of a company developing its own solution to meet unique, large-scale operational demands.

Even the way YouTube pages load and feel responsive is a result of internal tooling. The platform employs a lightweight JavaScript framework known as Structured Page Fragments (SPF). According to [Intuji](https://intuji.com/how-does-youtube-work/), SPF is "tailored for efficient navigation and seamless page updates within the platform," optimizing user experience by selectively updating page sections rather than requiring full reloads.

### **AI and Machine Learning: The Engine of Personalization and Accessibility**

Artificial Intelligence (AI) and Machine Learning (ML) are at the heart of many Google products, and YouTube is no exception. The platform's ubiquitous recommendation engine, which suggests what videos users might want to watch next, is a complex system driven by ML algorithms and neural networks. As [Intuji](https://intuji.com/how-does-youtube-work/) explains, this system "leverages user data, machine learning, and neural networks to recommend personalised content," constantly learning from viewing history and engagement patterns to enhance user satisfaction.

Beyond recommendations, Google's AI capabilities are also employed for crucial accessibility features. The [Google Blog](https://blog.google/technology/ai/9-ways-we-use-ai-in-our-products/) highlights that "YouTube uses AI to automatically generate captions for videos, making them more accessible to a wider audience, including those who are deaf or hard of hearing." This internal application of AI directly improves the platform for millions.

### **The "Eat Your Own Dog Food" Philosophy: Benefits and Considerations**

The practice of companies using their own products internally, often referred to by the adage "eating your own dog food," is widespread in the tech industry. As noted by [Splunk's blog](https://www.splunk.com/en_us/blog/learn/dogfooding.html) and [Wikipedia](https://en.wikipedia.org/wiki/Eating_your_own_dog_food), this approach serves as a powerful method for testing, quality control, and gaining firsthand insight into the user experience before products reach the wider public. Google’s product management philosophy, which includes "eat your own dog food" as a principle, emphasizes user focus and data-driven decisions ([Google Cloud Blog](https://cloud.google.com/transform/how-to-apply-google-product-management-practices-to-your-business)).

There was even a subtle public nod to this when, in 2011, YouTube added a license feature where the label was followed by the message "(Shh\! – Internal Dogfood)" on videos lacking commercial licensing ([Eating your own dog food \- Wikipedia](https://en.wikipedia.org/wiki/Eating_your_own_dog_food)). This highlights the active internal trials of new features.

**Benefits of this internal-first approach include:**

* **Enhanced Product Quality:** Issues are often identified and fixed faster when employees are the first users.  
* **Deeper User Empathy:** Developers and product teams gain a more profound understanding of the user journey, its pain points, and areas for improvement.  
* **Innovation and Scalability:** Building solutions for one's own complex needs can drive innovation and ensure systems are built to scale, as seen with YouTube's CDN and use of Bigtable.  
* **Cost Savings:** Utilizing in-house tools can be more cost-effective than relying on external vendors for certain specialized needs.

However, this methodology is not without its potential drawbacks:

* **Risk of Bias:** If the internal employee base isn't representative of the broader user population, products might be inadvertently tailored to a narrower set of needs or perspectives.  
* **Productivity Impacts:** Using early or buggy versions of software can sometimes hinder employee productivity.  
* **The "Not Invented Here" Syndrome:** An extreme focus on internal solutions could potentially lead to overlooking superior external tools or innovations.

### **Continuously Evolving Through Self-Reliance**

YouTube's journey showcases how a relentless focus on leveraging and developing internal technologies can be a powerful engine for growth, innovation, and maintaining a leading edge in the competitive digital landscape. By continuously using, testing, and refining its own systems—from core infrastructure like Bigtable and its custom CDN to user-facing AI-driven features and front-end frameworks—YouTube not only builds a more robust platform but also cultivates a deep, intrinsic understanding of its product's strengths and weaknesses. This internal feedback loop is crucial for navigating the evolving demands of its global user base and creator community.

While challenges exist, the commitment to using one's own tools reflects a profound confidence in the technology being built and a dedication to creating the best possible experience—an experience first validated by those who build it.


From Within: How YouTube's Own Tech Drives Its Global Platform


In the competitive landscape of AI-driven tools, the practice of a company using its own software is a powerful testament to its utility and a critical driver of its evolution. For Perplexity AI, the company behind the increasingly popular "answer engine," this internal use is not just a policy but a core part of its development philosophy. By leveraging their own conversational search technology in their daily workflows, the team at Perplexity is not only refining their product but also fundamentally shaping the future of how we access information.

At its heart, Perplexity's mission is to provide direct, accurate, and sourced answers to user queries, moving beyond the traditional list of blue links. To achieve this, their engineering team has built a sophisticated system that orchestrates multiple large language models (LLMs), including their own proprietary models, in concert with a robust search infrastructure. A key aspect of their development process, as highlighted in a report by [ZenML's LLMOps Database](https://www.zenml.io/llmops-database/building-a-production-grade-llm-orchestration-system-for-conversational-search), is "regular dogfooding of the product." This hands-on approach allows the team to experience the product just as a user would, leading to rapid identification of issues and a more intuitive understanding of where improvements are needed.

### **From the Inside Out: Building a Better Search Experience**

The internal use of Perplexity AI informs everything from the user interface to the core algorithms. When an engineer at Perplexity has a question, they don't turn to a traditional search engine; they turn to their own creation. This constant interaction provides immediate feedback on the quality of answers, the relevance of sources, and the overall conversational flow.

This iterative process is crucial for refining features like **Pro Search**, which is designed to handle complex, multi-step queries. As an engineer at Perplexity, William Zhang, shared with [LangChain](https://www.langchain.com/breakoutagents/perplexity), "It's harder for models to follow the instructions of really complex prompts. Much of the iteration involves asking queries after each prompt change and checking that not only the output made sense, but that the intermediate steps were sensible as well."1 This demonstrates a meticulous approach to quality, driven by the team's own expert usage.

The benefits of this internal feedback loop are evident in several key areas of the product:

* **Refined Reasoning:** By constantly testing the limits of their own system with complex questions, the Perplexity team can fine-tune the planning and execution steps their AI takes to arrive at an answer. This leads to more coherent and logically structured responses for all users.  
* **Enhanced Source Curation:** A core tenet of Perplexity is providing transparent and reliable sources. Internal use helps in identifying and prioritizing high-quality sources, ensuring that the answers are not only accurate but also trustworthy.  
* **Improved User Interface:** Experiencing the product daily allows developers and designers to identify and smooth out any friction points in the user journey, from asking a question to exploring the provided sources.

### **Navigating the Challenges of Self-Reliance**

While building on one's own technology is a powerful development strategy, it's not without its potential pitfalls. The very act of being an expert user can sometimes create a blind spot to the experience of a novice. A feature that seems intuitive to the creators might be confusing to a newcomer. Perplexity seems to mitigate this through a strong focus on user feedback and continuous evaluation, as noted in the ZenML report.

More significant challenges lie in the broader operational and strategic realms. A recent investigation by [Appknox](https://www.appknox.com/blog/is-perplexity-ai-safe-uncovering-security-flaws) highlighted several security vulnerabilities in Perplexity's Android app. While not directly a result of their internal usage model, it underscores the immense responsibility that comes with building and promoting a tool designed for widespread information access. The internal team's focus on functionality could, if not carefully balanced, overshadow the critical need for robust security.

Furthermore, Perplexity's strategic shift towards an advertising-based model, as reported by [AutoGPT](https://autogpt.net/ai-search-giant-perplexity-challenges-google/), introduces a new set of considerations. The internal culture, which has been focused on delivering the best, most unadulterated answers, will need to navigate the complexities of integrating sponsored content without compromising the user trust they have worked so hard to build. The risk of the "enshitification" engine, as one Hacker News commenter put it, is a real concern for any platform moving towards an ad-supported future.

### **The Path Forward: A Double-Edged Sword**

Perplexity AI's commitment to using its own product is undoubtedly a core reason for its rapid ascent and the high quality of its answer engine. This practice fosters a deep understanding of the product's strengths and weaknesses, leading to a more refined and user-centric tool. As Aravind Srinivas, CEO and co-founder of Perplexity, has alluded to, this internal validation is a crucial step before rolling out new features to the public.

However, the journey ahead will require a delicate balance. The team must continue to leverage its internal expertise to innovate while actively seeking and incorporating feedback from a diverse user base to avoid developing in a vacuum. The challenges of security and the introduction of advertising will test the company's commitment to its founding principles of accuracy and trustworthiness.

Ultimately, Perplexity's story is a compelling case study in the power of a company believing in its own creation. By being their own most demanding users, they are not only building a better product but are also at the forefront of defining a new paradigm for how we interact with and find knowledge in the digital age. The path they forge will be a valuable lesson for the entire software industry.

Perplexity AI: How The Answer Engine Builds Itself


In the software world, the practice of a company using its own products and services is a powerful, albeit sometimes complex, strategy for refinement and innovation. When a company's own workforce becomes a primary user base, the feedback loop can be incredibly direct, leading to rapid iterations and deeply relevant features. LinkedIn, the global behemoth of professional networking, is a fascinating case study in this regard. It not only builds sophisticated tools for the world but also extensively uses these very solutions to power its internal operations, shape its product roadmap, and cultivate its own workforce.

### Building on a Self-Made Foundation: Infrastructure as a Product

At the heart of LinkedIn's ability to serve over a billion users lies a robust, internally developed data infrastructure. This isn't just about servers and databases; it's a suite of sophisticated technologies born out of necessity and innovation. As detailed on their [LinkedIn Engineering blog](https://engineering.linkedin.com/teams/data/data-infrastructure) (LinkedIn Engineering, Data Infrastructure), tools like **Apache Kafka** (for real-time data streaming), **Apache Samza** (for stream processing), **Espresso** (a distributed NoSQL database), **Voldemort** (a key-value store), and **Pinot** (a real-time distributed OLAP datastore) were developed in-house to manage the colossal scale and complexity of the Economic Graph.

This internal technology stack isn't just for show. It's the bedrock upon which almost every LinkedIn feature is built, from your news feed and connection recommendations ("People You May Know") to job suggestions and search functionalities. By building and maintaining these critical systems, LinkedIn's engineers are their own first customers. They experience the pain points, identify bottlenecks, and drive improvements that directly benefit the external platform. For instance, the development of Kafka was a direct response to the growing need for reliable, scalable data pipelines to support analytics, monitoring, and messaging systems like InMail, as described in "[A Brief History of Scaling LinkedIn](https://engineering.linkedin.com/architecture/brief-history-scaling-linkedin)" (LinkedIn Engineering). This deep reliance on self-built infrastructure ensures that the tools are not just powerful but also resilient and optimized for the unique demands of a massive professional network.

### Connecting Talent: LinkedIn for LinkedIn Employees

It's perhaps no surprise that LinkedIn utilizes its own powerful suite of products designed for talent acquisition, development, and engagement for its own workforce. As HR Brew reported on LinkedIn's evolving tools, the platform has launched features like the "Next Role Explorer" to facilitate internal mobility and career development for its employees ([Francis Scialabba, Technically HR: New LinkedIn tools aim to connect internal candidates to roles and the tools to design their own careers, HR Brew](https://www.hr-brew.com/stories/2024/03/06/technically-hr-new-linkedin-tools-aim-to-connect-internal-candidates-to-roles-and-the-tools-to-design-their-own-careers)). Similarly, LinkedIn Recruiter isn't just a product for external clients; it's a vital tool for LinkedIn's own talent acquisition teams to identify and engage internal candidates.

This internal application goes beyond just HR functions. Microsoft, LinkedIn's parent company, has highlighted how they and LinkedIn are leveraging their combined technologies, including Microsoft Teams and Microsoft Viva (which integrates LinkedIn Learning), to enhance the digital employee experience for their own staff, especially in a hybrid work environment ([Microsoft, Microsoft and LinkedIn share latest data and innovation for hybrid work, Microsoft Blogs](https://blogs.microsoft.com/blog/2021/09/09/microsoft-and-linkedin-share-latest-data-and-innovation-for-hybrid-work/)). Employees using LinkedIn Learning for their own upskilling provide invaluable insights into the platform's effectiveness and user experience.

### The Entire Workforce as a Testbed: Everyday Usage Driving Insights

Beyond specialized tools, the everyday engagement of LinkedIn's thousands of employees with the core LinkedIn platform—their profiles, the feed, groups, articles, and messaging—creates a massive, continuous, real-world testing environment. While not always a formal "dogfooding" program in the traditional software testing sense, this pervasive internal usage inevitably surfaces bugs, usability issues, and ideas for improvement.

When employees rely on the platform for their own professional branding, networking, and industry insights, their experience directly informs the product's evolution. New features are often rolled out internally or to select groups of employees first, allowing for immediate feedback before a wider public release. This "living the product" culture means that the people building LinkedIn are also deeply immersed in its use, fostering a strong sense of ownership and a drive to enhance the user experience they themselves encounter daily.

Moreover, LinkedIn is increasingly leveraging Artificial Intelligence, building its own Large Language Models (LLMs) to power new functionalities like advanced job search and personalized content delivery ([Adam DeRose, LinkedIn has transformed HR over the last 20+ years. Its execs have big plans for its AI-powered future, HR Brew](https://www.hr-brew.com/stories/2025/03/21/linkedin-has-transformed-hr-over-the-last-20-years-its-execs-have-big-plans-for-its-ai-powered-future)). The development and refinement of these AI systems benefit significantly from the rich dataset generated by the platform, including interactions from its own employee base.

### The Double-Edged Sword: Potential Biases and Echo Chambers

However, this deep internal reliance is not without its potential downsides. One significant concern is the risk of creating an "echo chamber." If LinkedIn's employee base is not perfectly representative of its diverse global user community (in terms of technical proficiency, industry, cultural background, or even age demographics, as hinted by discussions around LinkedIn's "Gen Z problem" ([Chad & Cheese Podcast, LinkedIn Has a Serious Gen Z Problem, Chad & Cheese Podcast](https://www.chadcheese.com/post/linkedin-has-a-serious-gen-z-problem))), features and user experiences might inadvertently be optimized for this internal cohort, potentially overlooking the needs of other user segments.

Furthermore, the platform itself is not immune to biases. Research has highlighted potential algorithmic biases on LinkedIn, affecting network formation and visibility for different demographic groups. A study published in the Quarterly Journal of Economics found that connection requests from profiles of Black men were less likely to be accepted than those from white men ([Clark Merrefield, Field experiment on discrimination in building LinkedIn networks, The Journalist's Resource](https://journalistsresource.org/economics/discrimination-linkedin-network-building/)). Another experimental study suggested that LinkedIn's profile design could make it vulnerable to biased hiring decisions ([MoreThanNow, Bias On LinkedIn - An Experiment, MoreThanNow](https://www.morethannow.co.uk/single-post/2021/1/2/bias-on-linkedin-an-experimental-study)). If internal usage patterns and feedback are predominantly from a less diverse group, or if internal tools are tested on a skewed demographic, these biases could be inadvertently amplified or new ones introduced.

There's also the challenge highlighted by an [ERE.net article](https://www.ere.net/articles/is-linkedins-new-internal-hiring-tool-a-solution-to-the-wrong-problem) questioning whether internal hiring tools, while beneficial, might sometimes mask deeper cultural issues within organizations regarding internal mobility—a problem tools alone cannot solve. LinkedIn, like any company, must be wary that its internal solutions for its own context don't create blind spots for the broader market needs.

### The Network Effect, Internally Magnified

Despite these challenges, LinkedIn's practice of deeply integrating its own technologies and platforms into its daily operations appears to be a significant net positive. It fosters a culture of continuous improvement, provides rapid feedback loops, and ensures that the engineers and product teams have a profound understanding of the tools they are building.

The sophisticated data infrastructure built by LinkedIn for LinkedIn is a testament to solving immense scaling challenges head-on. The use of its own professional development and networking tools by its employees provides a constant stream of real-world usage data.
