YC-backed @Mintlify (YC W22) just announced a $45M Series B round, bringing their total funding to $67M, to "accelerate [their] mission of building the knowledge infrastructure for AI."

Read in their blog announcement:

Mintlify now powers documentation for over 20,000 companies, with content reaching more than 100 million people every year. This round accelerates our mission to become the knowledge layer that makes products understandable, usable and discoverable by AI agents.

The more visible I become on platforms, the more opportunities I receive (not just sponsored ones).

Quite often, people reach out saying they re looking for a marketing co-founder.

And practically every month, there s someone with another revolutionary idea, the next big thing, a multimillion or multibillion-dollar business but then you never hear about them again.

There's never been a better time to build. AI tools, smaller teams, faster product cycles.

Last year, @Supabase surveyed over 2,000 startup founders and builders to uncover what's powering modern startups: tech stacks, GTM, and approach to AI. [1]

Many things have changed since then, and they want to know what building at startups looks like in 2026.
