AI-Generated Summary

Key Takeaways

  • Product-market fit validation: After eight failed pivots over 18 months, the founders recognized true product-market fit when customers asked to implement immediately instead of scheduling follow-ups, paid $20 invoices within minutes, and demanded same-day setup rather than waiting for scheduled demos. This stark contrast to previous lukewarm responses eliminated any doubt about finding the right solution.
  • Early sales motion that scales: Mintlify manually migrated customers and reviewed their documentation for free, fixing grammar and restructuring content despite the time cost. When advised this approach wouldn't scale, Paul Graham told them this exact process would become their permanent differentiator. They now have teams and AI tooling supporting this white-glove migration service for thousands of customers.
  • Documentation as AI infrastructure: Documentation shifted from optional reference material to operational infrastructure because coding agents, support bots, and internal tools now consume docs directly. When documentation contains errors like incorrect pricing information, thousands of AI agents propagate those mistakes at scale, making accuracy critical rather than aspirational for modern software companies.
  • Self-updating docs unlock: Three convergent factors enable automated documentation updates in 2025: increased organizational need as AI agents amplify documentation errors, model capabilities reaching reliability thresholds with Claude Opus 4.5, and enterprise comfort providing context to language models that didn't exist two years ago. This solves a 25-year-old problem of perpetually outdated documentation.
  • Expanding beyond developers: Mintlify now powers help centers, internal knowledge bases, and HR policy documentation because non-technical users increasingly understand markdown through AI tool usage, and engineers influence purchasing decisions for support and knowledge products since AI agents require their technical input. The market expanded as coding literacy spread beyond traditional developer roles.

What It Covers

Mintlify cofounders Han Wang and Hanby Li discuss how documentation evolved from static reference material into critical infrastructure for AI agents and coding tools. They share their journey through eight pivots, early customer acquisition strategies, and building self-healing documentation that updates automatically as codebases change.

Notable Moment

When preparing for a driver's license test, one founder discovered the study materials were hosted on Mintlify, illustrating how far beyond developer documentation the platform had spread. This unexpected use case revealed the product's evolution from technical documentation into general knowledge management, serving audiences the founders never anticipated when building for developers.

Episode Transcript

Hey, guys. Here's your docs that are way better now on their website. Take a look. And that's when I realized the beauty of having failed so many times, which was in failing so many times and building so many ideas that didn't work, when something did, there was no mistaking it. That's very important to solve one problem correctly. And even right now, as we're experimenting and launching new products, we're we're hyper focused on getting one person who loves what we're building as opposed to a thousand people who are going to just feel meh about it. Still the small things that don't scale that really spark the customer love. The thing that goes the extra mile, if you will, is how we can do that things. Right? If you go the extra mile that in a way that people don't expect, you know, imagine. For most of the Internet's history, documentation has been an afterthought. Something you write after the product ships, something meant to explain what already exists. But what happens when the reader isn't human anymore? For decades, docs were written for people. They explained APIs, answered questions, and slowly drifted out of date as products evolved. That decay was accepted as normal because documentation was treated as reference material, not infrastructure. In the last few years, that assumption has broken. Coding agents, support bots, and internal AI tools now read documentation directly. Docs are no longer just explanatory, They're also operational input. When they're wrong or outdated, systems break. This creates attention. Documentation matters more than ever, but keeping it accurate has always been one of the hardest problems in software. Static docs don't survive fast moving products, especially in an agent driven world. In this episode, we explain how documentation is changing, why static dogs are failing, and what it would take to build documentation that stays reliable as software evolves. Our guests are Hanh Wang and Hanh Bi Li, cofounders of Mitlify, joined by a 16 z general partner, Jennifer Li, and a 16 z partner, Yoko Li. I'll start the podcast with with this question. Given you're at the center of seeing how agent has seen packet coding because you're building a documentation product that's serving all the developer tools, the most popular ones, how have you seen the transition from the starting point of building Mellify to what a role of a coding agent plays now? I mean, it's so different now. Right? I think and it's and it speaks a lot to even how much has changed in such a short amount of time. Right? I remember when Hanby and I, you know, decided we kinda wanted to embark the journey of wanting to go build something that helps developers. Right? The first thing that came to our mind, this was, like, to paint the picture, like, early twenty four late twenty three, early twenty four. We were just like, let's go build something that could impact developers, help …
