How does AI investor matching work?

Our AI reads your pitch deck to extract stage, sector, geography, business model, traction, and ask, then ranks investors by real thesis fit — using each investor's stated focus, portfolio history, check-size range, and recent deal activity. You get a shortlist of investors most likely to take the meeting, ranked by a banded confidence score with citations, not a fake percentage.

How do I find investors for my startup?
