Free resources on both sides of the table, but aimed at different people.
OpenVC is a free, crowd-contributed database of VC funds, built primarily to help founders find and filter investors for their raise. VC Deal Flow Signal is an investor-side product that surfaces technical startups before a fundraise begins. Both are free at the core tier, and both are deliberately open, but they serve opposite roles in the venture pipeline.
OpenVC's signal is transparency about which funds exist, what they invest in, and how to reach them. VC Deal Flow Signal's signal is engineering tempo on technical startups, read from public code.
OpenVC does not produce timing signals; it is a directory. VC Deal Flow Signal surfaces engineering-acceleration 6-12 weeks before a visible fundraise.
OpenVC is free for founders; paid premium options exist for enhanced filtering and outreach tooling. VC Deal Flow Signal is free at its core tier and EUR 9.97 per month for beta paid features.
OpenVC aggregates crowd-contributed fund profiles, thesis information, and partner contact data. VC Deal Flow Signal draws from public GitHub activity with methodology on SSRN.
OpenVC covers thousands of VC funds, filterable by stage, geography, and thesis. VC Deal Flow Signal covers technical startups publishing code.

Occasionally, for competitive mapping of other funds. Its primary audience is founders.
No. It is focused on company-side signals, not on indexing VCs.
Indirectly. A founder could compare their engineering signal against similar companies, but the product is built for the investor-side use case.
Yes, both have genuine free tiers. VC Deal Flow Signal's weekly report and sector pages are free forever; OpenVC's core fund database is free for founders.
