About

What is Affinity

Affinity captures activity from email and calendar automatically, enriches contact profiles, scores relationships based on historical interactions, and writes notes and tags back to the CRM without manual input. It is built for RevOps, GTM leads, and deal teams at mid-market to enterprise private capital firms — PE, VC, and investment banking — where relationship context is the primary sourcing edge. The standout capability is relationship mapping: Affinity identifies commonalities across your firm's network and surfaces warm introduction paths that would otherwise stay buried in inboxes. It also generates market maps for competitive benchmarking and attributes opportunities back to the contacts that originated them. The platform is purpose-built for private capital workflows and is a poor fit for high-velocity B2B sales teams that need multichannel sequencing or outbound cadence tooling.

Our verdict

Vanderbuild take

For RevOps and GTM leads at private capital firms, Affinity is the most purpose-specific CRM in this subcategory — it's not trying to be a horizontal sales tool, and that focus shows in how deeply it handles relationship attribution and pipeline context. On the agentic readiness front, this is as native as it gets: the hosted MCP server (available from the Scale plan at $2,300/user/year) makes Affinity's CRM data directly callable by Claude, Gemini, and Copilot, which means you can wire it into an AI orchestration layer without building custom middleware. Pricing starts at $2,000/user/year on an annual seat basis — accessible for a small deal team, but costs compound quickly as headcount grows, and API access is gated entirely behind paid tiers. The honest limitation is scope: if your team needs outbound sequencing, multichannel cadences, or broad B2B prospecting, Affinity won't cover that ground — you'll need a separate tool in the stack.
