VCbacked▲181
I built this for anyone whose business revolves around funded startups — whether you're a VC tracking new raises, a sales team targeting high-growth companies, a recruiter staffing fast-scaling teams, or an agency looking for clients with fresh capital to spend. The problem I kept running into: Crunchbase has data but no contacts. Apollo has contacts but isn't curated for VC-backed companies. PitchBook and CB Insights are $5–25K/year and overkill for most use cases. We manually verify every contact and add 500+ new leads monthly.
