The rise of AI has transformed more than just user-facing applications it has redefined the way we think about infrastructure, data architecture, product design, and customer feedback. In a time when companies rush to adopt AI chatbot solutions and ride the wave of generative technologies, few are asking the deeper, more foundational questions: How should we build for AI? What are the systems, structures, and mindsets needed to create truly AI-native products?

One of the most thoughtful explorations of these questions comes from DevRev’s blog, The Book of DevRev. It’s a rare combination of technical depth, product thinking, and operational insight crafted for builders who want more than surface-level announcements.
Semantic Search at Scale: More Than Just Vectors
A standout post from DevRev dives deep into how they built semantic search at scale. But this wasn’t just a matter of plugging in OpenAI embeddings and using a vector database. Instead, DevRev integrated search with a wide range of platform signals: support content, customer usage data, feedback history, and even dynamic updates from support tickets and product teams.
This tight integration is made possible by their purpose-built vector infrastructure. Unlike traditional models that rely on external APIs or generic vector engines, DevRev’s platform is optimized for both speed and flexibility. This ensures that every query can retrieve the most contextually relevant answer, powered by AI and grounded in real-time customer signals.
Such infrastructure is not only technically impressive, but it also addresses a core challenge of AI chatbot systems today: interoperability between multiple data sources and human inputs. By connecting vectors directly to dynamic usage and feedback loops, DevRev ensures their semantic systems are constantly improving.
Velocity as a First Principle
Beyond infrastructure, DevRev emphasizes velocity as a first principle in AI-native environments. In traditional development cycles, feedback often moves slowly weeks or months after product release. But in today’s AI-driven landscape, where models are retrained regularly and interfaces evolve with each user interaction, shipping fast and iterating faster is no longer optional. It’s mission-critical.
This is especially true for teams using platforms like ChatGPT and Bing Chat, where Microsoft has shown how quick iteration and constant learning drive better search and chat experiences. In this context, velocity is not just about engineering speed, it’s about organizational design, tooling, and how chatbot products can evolve on a weekly, even daily, basis.
The Four Horsemen Framework: Unified Feedback Loops
Perhaps the most innovative idea in DevRev’s content is the Four Horsemen framework a way to break down silos and align key functions like product, growth, engineering, and support. Instead of isolated teams, DevRev uses integrated systems that share data and insights in real-time. This enables a unified feedback loop where customer issues inform product decisions, product changes fuel growth, and growth insights improve support documentation.
For instance, when users interact with a chatbot on the platform, their feedback can instantly trigger updates to documentation, flag bugs to engineering, or even generate new growth ideas. This real-time loop not only boosts AI chatbot effectiveness but also ensures every part of the company is working from the same data.
Honest Content in a Hype-Driven World
In a space flooded with announcements regarding AI, it’s refreshing to find content grounded in first-principles engineering. DevRev doesn’t just talk about the future, they show you how they’re building it. Whether it’s building on top of ChatGPT with Bing, leveraging platform intelligence, or using Microsoft Build principles to structure internal systems, their blog reflects a genuine commitment to operational excellence.
This kind of tactical transparency is especially valuable for parents, startups, developers, and product teams looking to cut through noise. As more companies explore AI tooling and look to use AI across workflows, the need for robust, extensible, and fast platforms becomes essential.
Conclusion: Building the Stack for the Future
DevRev’s approach is a masterclass in AI-native product development. By investing deeply in vector infrastructure, prioritizing velocity, and designing for interoperability and unified feedback, they are showing what the future of software development looks like.
In an age where “AI” is often a buzzword, DevRev provides a clear, executable vision, backed by code, use cases, and strong product thinking. For those looking to build the next generation of tools and experiences, their work is a powerful reminder: To build for AI, you must rethink everything from data pipelines to team structures, from product analytics to chat and search.
