Relationship intelligence versus engineering signal: two different bets on where deals come from.
Affinity built its business on the premise that deals come from relationships, and that the CRM should surface the strongest paths into each company. VC Deal Flow Signal starts from a different premise: that the best deals are often discovered before the introductions materialize, by watching public engineering signals. The two tools answer different questions and many funds end up using both.
Affinity treats your team's collective network as the primary signal. Warm paths, email cadence, and relationship strength drive workflow. VC Deal Flow Signal treats public GitHub acceleration as the primary signal and is agnostic to who knows whom.
Affinity surfaces companies once someone on your team touches them, which usually means a warm intro or an inbound pitch. VC Deal Flow Signal typically surfaces technical startups 6-12 weeks before a visible fundraise, based on engineering tempo changes.
Affinity pricing is per-seat enterprise, tiered, and negotiated through sales. VC Deal Flow Signal offers a free weekly report and sector pages, with an optional EUR 9.97 per month beta tier for the dashboard and alerts.
Affinity ingests your email, calendar, and CRM activity, then enriches with Crunchbase-style company data. VC Deal Flow Signal pulls from GitHub commit velocity, contributor growth, and release cadence, with a published SSRN methodology.
Affinity covers every company your team has ever emailed, which tends toward breadth across sectors. VC Deal Flow Signal is narrower: technical startups with public code, where engineering is a leading indicator.

Pick VC Deal Flow Signal if
You want to discover technical startups ahead of the warm-intro cycle, and your sourcing edge is reading the signal earlier rather than having more relationships.
Pick Affinity if
You run a multi-partner fund where the sourcing bottleneck is coordinating who knows whom across the firm, and you need a CRM built around relationship paths.
Verdict
Affinity is the right answer if your problem is operationalizing a large relationship graph across partners. VC Deal Flow Signal is the right answer if your problem is finding technical companies before anyone else knows about them. The two tools complement each other more than they compete.
Yes, many funds do. Affinity handles pipeline and relationship tracking, while VC Deal Flow Signal feeds early-stage technical leads into the top of the funnel.
Not as a built-in signal. Affinity focuses on relationship intelligence and can ingest external data, but engineering-acceleration scoring is not part of its core product.
No. It is a signal and discovery tool. It pairs well with a CRM like Affinity, a spreadsheet, or a lightweight tracker.
Affinity is enterprise SaaS priced per seat and negotiated. VC Deal Flow Signal has a free tier and a flat beta paid tier at EUR 9.97 per month.
