What Is Deal Flow Software
Deal flow software helps investors source, track, and manage investment opportunities. Definition, sourcing vs tracking tools, and free options for angels.
Direct answer
Deal flow software is a tool that helps investors source, organize, and manage investment opportunities. It splits into sourcing tools that surface new startups, and tracking tools (deal CRMs) that manage the pipeline once deals are in. GitDealFlow is a sourcing layer that reads public GitHub activity to flag startups 21 to 47 days before they raise.
Deal flow software is a catch-all for the tools investors use to find and manage potential investments. It is not one product category but two, and mixing them up is the most common mistake new angels make when they go tool-shopping.
Two jobs, two kinds of software.
1. Sourcing tools answer "who should I look at next?". They surface startups from data, networks, or signals before the round is announced. Crunchbase and PitchBook surface startups from funding databases, GitHub-based tools like GitDealFlow surface them from public engineering activity, and deal-marketplace platforms surface them from founder submissions. 2. Tracking tools (deal CRMs) answer "where is this deal in my pipeline?". They store notes, stage, ownership, and follow-ups once a deal is already in. Affinity, Attio, and 4Degrees are fund-grade trackers; a Notion database or Airtable base is what most solo angels actually use.
What separates a sourcing tool from a tracker. A tracker organizes deals you already have; a sourcing tool generates deals you did not. The highest-leverage free stack for an angel is a free sourcing layer (a weekly signal digest or a public API) feeding a free tracker (a spreadsheet, Notion, or Airtable).
Where GitDealFlow sits. GitDealFlow is the sourcing layer: it reads public GitHub activity (commit-velocity change, contributor growth, infrastructure buildout) across 350+ startups in 15 sectors and flags the ones accelerating 21 to 47 days before a fundraise announcement, historically. The Signal Digest is free, and the JSON, CSV, MCP, and function-calling APIs are free and unauthenticated.
What deal flow software is not. It is not a fund, an investment advisor, or a source of investment advice. Sourcing tools surface data, not recommendations. A tracker remembers your pipeline; it does not judge it. Any tool that promises to pick winners for you is describing itself beyond what the data supports.

Frequently asked questions
What is the difference between deal flow software and a CRM?
A CRM tracks relationships; a deal tracker tracks opportunities. Deal flow software usually combines a sourcing feed with pipeline tracking, while a general CRM (Salesforce, HubSpot) is tuned for sales, not stages like 'sourced', 'in diligence', 'passed', or 'invested'.
Is there free deal flow software?
Yes. The sourcing side has free options including GitDealFlow's free Signal Digest and public API. The tracking side has free tiers from Notion, Airtable, and HubSpot's free CRM. Fund-grade trackers like Affinity and Attio are paid.
How is GitDealFlow different from Crunchbase or PitchBook?
Crunchbase and PitchBook are databases that record a round after it happens. GitDealFlow is a leading-indicator tool that surfaces engineering acceleration 21 to 47 days before the round. They are complementary: use GitDealFlow to find, then a database to verify stage and ownership.
Do I need deal flow software as a solo angel?
Not as a fund does. A solo angel writing a handful of checks a year can run a free stack: a weekly signal digest for sourcing and a Notion or Airtable base for tracking. You graduate to a paid deal CRM when your pipeline outgrows a spreadsheet.
