Deal Flow CRM: What Early-Stage Investors Actually Use

What a deal flow CRM is, and is not. A deal flow CRM is the record of your sourcing process: every founder you meet, every note, every next-touch date. It is not a discovery engine and not a database; it only contains what you put in. That distinction drives the whole buying decision: the CRM optimizes the pipeline you already have, while sourcing fills the pipeline the CRM then records.

The 2026 landscape, honestly positioned. Affinity is the VC-native standard and holds the largest share among US firms above $250M AUM, priced at firm-level annual contracts. Attio is the flexible challenger: custom data models, a free plan, and per-seat pricing that suits small funds. Airtable and Notion are the DIY route, free to start, unlimited flexibility, but they will not deduplicate relationships or enrich company data for you. HubSpot's free CRM covers generic pipeline tracking. Specialist tools like 4Degrees and Zapflow sit between the DIY and enterprise tiers.

Affinity vs Attio vs Airtable: the actual decision. Pick Affinity when relationship intelligence and automatic data enrichment justify the contract, typically once the fund manages hundreds of live relationships. Pick Attio when you want a real CRM but need custom fields and a lower bill. Pick Airtable or Notion while the pipeline is under fifty companies and one person owns the process. The trap is staying in the spreadsheet too long: after a year of sourcing, a year of founder history has accumulated, and migration gets expensive.

What the CRM still cannot do. No CRM sources deal flow; it records. The top of the funnel comes from networks, events, inbound, and signal feeds. A free weekly signal feed (350+ startup orgs, 15 sectors, ranked by GitHub commit-velocity acceleration) plugs into any CRM via API, MCP, or CSV, so the CRM receives a ranked list of companies to track instead of waiting for the network to deliver them.

The spreadsheet and template route. For first-time fund managers, an Excel or Airtable template is the right starting point: pipeline stage, founder, contact, source, next-touch date, notes. The free digest and CSV export make the template easy to seed each week. Move to a native CRM when deduplication and relationship history stop being manageable by hand, usually around fifty live companies.

How GitDealFlow fits. GitDealFlow is a signal feed, not a CRM, and it does not compete with Affinity or Attio. It feeds whichever CRM you use: the weekly digest, free API, and MCP server push ranked engineering-acceleration lists that become CRM rows. The comparison that matters is signal feed plus CRM versus CRM alone, because the CRM alone cannot see a company before it announces.
