How do I raise money for a startup?

Raising money for a startup follows a repeatable playbook: (1) tighten your pitch deck around problem, solution, traction, market, and ask; (2) build a targeted list of investors whose thesis, stage, and check size actually fit your round; (3) run structured outreach with warm intros where possible; (4) manage the pipeline in a fundraising CRM so no lead goes cold.

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?

The fastest way to find investors is to filter by fit rather than by name. On StartupFundraising.com you can filter 75,000+ investors by stage (pre-seed to Series C), sector, geography, check size, and recent activity — then see who in your existing network can make a warm intro.
