Free lens
Put the signal where you already look.
The Chrome extension is not a paid tier. It is a free surface that drops GitDealFlow’s signal directly onto Crunchbase and Wellfound so you can spot momentum without opening another tab.

You have five minutes to keep this install session active before it resets.
Why this exists
If you already check Crunchbase or Wellfound, the signal should meet you there instead of asking you to remember one more dashboard.
What it does
- Shows the signal on Crunchbase and Wellfound profiles
- Lets you see momentum without changing workflow
- Acts as a free lens on top of the public web
- Keeps the surface lightweight and frictionless
Where it sits in the ladder
This is a bonus surface, not a conversion step. It helps you notice the signal in-context.
The conversion still happens on the apex. The free Sunday email is the main path.
The deeper proof still lives on signals.gitdealflow.com.
Why this matters
You get the output where you already work.
The extension turns deeper public engineering work into a simple, visible signal on the pages you already check.
Privacy and methodology
No account. No telemetry. No cookies. The extension checks the page URL, queries the public GitDealFlow surface, and renders the signal inline.

How it fits a full sourcing workflow: The 10 best Chrome extensions for VC deal flow (2026)
Why This Page Exists
GitDealFlow is a public deal flow signal dataset: 350+ startup GitHub organizations across 15 sectors, refreshed weekly, with breakout teams surfacing 21 to 47 days before their round is announced. This page makes one part of that system legible: what it measures, how it is computed, and how to use it in a live sourcing workflow. The method is published end to end and falsifiable by design, with the working paper on SSRN and the dataset downloadable under CC BY 4.0.
Start Here
A practical read-through of Put the signal where you already look.: the dataset behind this page refreshes weekly across 350+ organizations and 15 sectors, and every figure shown traces to a public GitHub REST API pull. That matters for two reasons. Reproducibility: any number here can be re-derived from primary sources, which is the standard the published methodology sets for itself. Timeliness: engineering acceleration precedes announcements, so this page follows the data cadence rather than the news cycle, and the freshness endpoint always reports the exact pull date.
If Put the signal where you already look. is your entry point, the fastest next steps are fixed: skim the glossary for the three or four terms that anchor the topic, open the research dataset to see the raw weekly snapshots behind the summary numbers, and run one live query against the free momentum checker with a company you already know well. Seeing the signal fire on a familiar name is the quickest way to judge whether code-side sourcing belongs in your own workflow.
