Arc5 Ventures provides flat-fee technical due diligence for angel investors and small VCs evaluating AI and technical startups. You are moving fast on a deal. The founders sound sharp.

Small VCs
Sub-$100M funds without in-house technical staff on every deal.
Angel investors & angel groups
Writing checks into AI or technical companies and want a second set of eyes.
Syndicate leads
Need to back up your conviction with a credible technical memo for LPs.
Founders co-investing
You know product but want an independent read on the stack before committing.
Written report
1–2 page structured memo: findings, risk flags, and a plain-language verdict.
Live debrief
30–45 minute call to walk through findings and answer your specific questions.
Fast turnaround
48–72 hours from scoping call to delivered report. Most deals are in that window.
Flat fee per engagement. No retainer. No ongoing commitment.

Complex deals, larger checks, or situations where you need deeper evidence.
Recent diligence signal
Identified three undisclosed vendor dependencies in a $500K pre-seed round before close.
Real operator
Hands-on fractional CTO with active portfolio companies and production AI systems shipped. Not a consultant who theorizes from the sideline.
AI-native
Built and deployed AI systems across production environments. Knows what real AI infrastructure looks like versus a GPT wrapper with a polished demo.
Code-capable
Actually reads the code when it's accessible. Not just reviewing decks and talking to founders.
Investor mindset
Active angel investor. Knows what matters for returns, not just what's technically impressive.
Start asynchronously if you already have the deal in motion. If the fit is clear, we can scope quickly and move into diligence without adding calendar friction.
