Why You Need a Thesis
An investment thesis forces you to be disciplined. Instead of chasing every shiny deal, you invest in the areas where you have an edge, whether that's domain expertise, network access, or signal interpretation.
GitDealFlow helps you operationalize your thesis: filter sectors you understand, track engineering momentum in your focus areas, and build a deal pipeline that aligns with your strategy.
Components of a Thesis
Sector focus: Which 1-3 sectors do you understand deeply enough to evaluate deals? Generalist angel investing underperforms sector-focused investing.
Stage preference: Pre-seed (higher risk, lower valuation, longer hold), seed (proven team, traction), or Series A (institutional-grade, lower returns).
Check size: $10-25K per deal for angels. Reserve 50% of capital for follow-ons.
Portfolio size: 20-30 companies over 5 years for meaningful diversification.
Value-add: What can you offer beyond capital? Network, expertise, operating experience.
Writing Your Thesis Down
Write it, share it with a trusted peer, and refine it. A written thesis prevents rationalization ('this deal is special').
Review your thesis quarterly. Markets change and your thesis should evolve. GitDealFlow's sector data can inform thesis evolution.
Context: Where This Fits
This explainer is part of a library built on a single dataset: public engineering activity across 350+ startup GitHub organizations, 15 sectors, refreshed weekly. The through-line is that deal flow signal is earliest in code: breakout teams appear 21 to 47 days before their round is public. Concepts on this page are defined precisely because imprecise vocabulary is what makes sourcing decisions unfalsifiable.

A practical read-through of How to Build an Investment Thesis for Angel Investing: 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 How to Build an Investment Thesis for Angel Investing 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.
Frequently Asked Questions
How specific should my thesis be?
'Fintech seed deals, $25K checks, 20-30 companies over 5 years, reserve 50% for follow-ons' is specific enough. 'Tech startups' is not a thesis.
Can I change my thesis?
Yes, but deliberately, not reactively. Review quarterly. GitDealFlow's sector momentum data can inform whether your thesis sectors are still active.
Do angels really need a thesis?
Angels without a thesis are tourists. They make 5-10 random investments and hope for the best. Angels with a thesis build systematic portfolios that produce consistent returns.
