YC just dropped their new RFS for F25 — anyone building in these spaces?

@Y Combinator recently published their latest Request for Startups (RFS) for the Fall 2025 batch — and it’s packed with some really interesting problem spaces.

I’m curious — is anyone here already building something that aligns with one of these ideas? Or considering pivoting toward one?

Also, are you applying to YC this batch? Would be cool to hear what you’re working on (or thinking about applying with). Always fun seeing how others interpret the RFS prompts!
