Mintlify Raises $45M Series B to Build AI-Ready Code Documentation Infrastructure

Mintlify just minted something bigger than capital, they minted signal, and in this market, signal is the only currency that does not get inflated. $45M in Series B, co-signed by Andreessen Horowitz and Salesforce Ventures, with Bain Capital Ventures, Y Combinator, MVP Ventures, Avra, HubSpot Ventures, and TwentyTwo Ventures all leaning in like they have seen this pattern before and know how it ends, because when that many sharp minds show up to the same table, it is rarely for small talk.

Han Wang and Hahnbee Lee did not stumble into this, they built Mintlify in 2022 out of a frustration most developers just accept, documentation that feels like it was written by someone who never met the product, so they went the other way and built for the ones reading and the ones parsing, humans and machines, because in a world where AI agents are no longer guests but operators, your docs are not a side dish, they are the interface.

That is where Mintlify starts to play with its name a little, mint as in fresh, mint as in printing value, lify as in bringing something static to life, because documentation used to sit there aging quietly, collecting dust and confusion, and now it breathes, updates, responds, it is not just read, it is queried, interpreted, executed against.

The quiet part that deserves more volume is this shift from docs as support to docs as infrastructure, where documentation becomes the layer AI depends on to understand your product and stops acting like a cost center and starts acting like leverage, which is how over 20,000 companies end up on your platform and more than 100M developers interact with what you have built whether they realize it or not.

And here is where the investors are not just placing bets, they are following gravity, because if AI agents are going to touch every product, they need clean, structured, living knowledge to do it well, and Mintlify is positioning itself right in that flow where every query, every answer, every interaction depends on the quality of what sits underneath.

There is also a discipline in how this round came together, where returning investors like Bain Capital Ventures and Y Combinator do not double down out of nostalgia but because the numbers and behavior line up with conviction, while new capital from Salesforce Ventures adds a different layer with distribution thinking, enterprise gravity, and a sense of where this goes when it leaves the developer sandbox and walks into the boardroom.
