What is the Sieve MCP Server?

AI startup due diligence — screen companies across 7 dimensions, get a Sieve Score.

The short version

Most VCs screen 50+ deals a month. Most of those are obvious passes — but you still spend 2-3 hours per deal on basic diligence before you know that. Sieve does that work in 5 minutes.
