How to use the directory

Start with fit. Stage, sector, and geography rule out most investors before the pitch does: a fund that writes Series A checks won't take a pre-seed meeting, however strong the deck. Use the searchable version to build a short list of organizations that fund companies like yours, then read up on each one before you reach out.
