Broad private-market coverage versus one sharp early-stage signal.
SourceScrub is an enterprise platform for private-market sourcing, blending a curated company database with conference, hiring, and web data. VC Deal Flow Signal operates with a narrower scope: one signal on technical startups, documented and inspectable. The tools attack different parts of the sourcing problem.
SourceScrub's edge is the depth of its private-company coverage and the analyst work behind it. VC Deal Flow Signal's edge is a single, well-defined engineering signal with a public methodology.
SourceScrub helps you find companies that exist but are hard to discover, and gives you context once you find them. VC Deal Flow Signal is timing-focused: 6-12 weeks before the visible fundraise on technical companies.
SourceScrub is enterprise SaaS with tiered contact-sales pricing typical of private-market data. VC Deal Flow Signal offers a free core tier and a EUR 9.97 per month beta paid tier.
SourceScrub combines analyst-curated data, conference rosters, hiring signals, and web data. VC Deal Flow Signal reads public GitHub activity only, with methodology on SSRN.
SourceScrub covers a broad universe of private companies across many sectors. VC Deal Flow Signal covers technical startups that publish code.
