Angel Copilot – open-source tool for assessing startup deals
Custom GPT wrapper that generates investment memos and ranks dealflow for angel investors.

AI due diligence for angels, but Carta, AngelList, and Pitchbook already own this.
Angel investors, early-stage deal makers

I built Brevoir after watching an angel investor I know closely make five figure decisions off a 15 minute pitch and a gut feeling. No research infrastructure, no analyst, just vibes and a deck. Turns out this is basically everyone's problem in early stage investing.
The individual investor market exploded over the last decade. The tooling never kept up. What exists was built for institutions with research teams and analyst budgets. Nobody built the infrastructure layer for the person writing their own checks.
Brevoir is that layer. Drop in a pitch deck or company URL and the platform runs a full due diligence report across 7 sections: founder background, market validation, competitor mapping, traction signals, risk flags, comparable analysis, and a Brevoir Score. Under 2 minutes. Parallel research agents, best in class OCR and web crawling, and a lot of investment specific logic built on top to make the output decision grade, not just a summary.
We also just shipped a full deal management platform on top of it. Kanban pipeline, deal rooms, tags, CSV import. Brevoir is the operating system for how an individual investor runs their entire deal flow from first look to decision.
First report is free, no credit card. Would love feedback from anyone who evaluates startups. brevoir.com
Custom GPT wrapper that generates investment memos and ranks dealflow for angel investors.
Type a company name or website and the tool claims to auto-identify the startup, pull 50+ signals, map your investment thesis to a scoring model, and return strategic-fit, market and risk breakdowns in ~60s without signup. Smart triage UX — great for rapid deal screening — but the methodology and source weighting are opaque, so this feels like a useful first-pass tool rather than anything you’d stake capital on without follow-up.
Finally, a portfolio tracker that handles private equity and SAFEs properly.
Early-stage IP auditor competing against manual audits and established security tools.
The thesis is timely: if AI shortens iteration cycles, angels need new heuristics, not slower due diligence. The Amazon listing itself offers nothing beyond the usual storefront metadata — no standalone landing page, no sample frameworks, and no quick, actionable checklists, which would have made the idea much easier to evaluate and share.
