Individual investors writing personal checks, often operators or former founders who add domain expertise alongside the money.
Angel investors are high-net-worth individuals who invest their own capital into early-stage startups. They write smaller checks than institutional seed funds but are typically faster to decide, lighter on diligence, and often bring direct operating experience or domain expertise. The best angels become long-term advisors who can make introductions, recruit early hires, and help navigate the next round.
$10K – $250K (super-angels occasionally write $500K-$1M)
Pre-seed and seed; occasionally Series A
0.5% – 5% at entry, usually via SAFE
Angels range from former founders and senior operators at scaled startups to industry executives and family-office principals investing on the side. Many angels invest through syndicate platforms (AngelList, Sweater) that pool individual checks into a single SPV, which simplifies cap-table management for the founder. Super-angels operate with venture-like cadence and write meaningfully larger checks than traditional angels.
Angels invest in people first. They want to back founders they would want to work with again, working on a problem they personally find interesting and credible. Domain fit between the angel and the company matters: an angel who has built a developer-tools company is much more likely to lean in on another developer-tools pitch. Many angels make decisions inside one or two meetings, with diligence consisting mostly of reference calls.
Most angel investments today are made on SAFEs (Simple Agreements for Future Equity) or convertible notes rather than priced rounds, with check sizes between $10K and $250K. Standard pre-money valuation caps are between $5M and $20M for a typical seed-stage company; super-angels may negotiate uncapped notes or priced rounds. Pro-rata rights are common but not universal; information rights are minimal.
Why am I the right angel for this round, what is the path to this becoming a multi-billion-dollar outcome, do I have time to be helpful, and is there a chance the company gets stuck between angel and Series A. Most angels also ask whether the company can be capital-efficient enough to reach default-alive status without a traditional venture round, since that protects their investment.
Keep the deck short — 10 to 12 slides — with high signal density on each. Open with the founder story and the problem, then move quickly to traction or evidence. Make the ask explicit about what role you want the angel to play beyond capital, and identify two or three other angels or institutional investors you are courting so the angel knows the round is real.
Decks that read like institutional pitches rather than founder-to-investor conversations, founders who cannot articulate why they personally are obsessed with the problem, and rounds with no other committed investors. Angels also screen out founders who treat the investment as transactional rather than relational — the best angels expect to be brought into hard decisions over the next several years.
