Angel Investors: How to Find, Evaluate, and Work With Them

Angels are individual investors writing personal checks. The best angels transform the trajectory of a startup. Here's how to find and work.

Angel Investors for Startups

A great angel is a founder-friend with capital, opinions, and a network. A bad angel is a nuisance shareholder with strong opinions and no leverage. Choose deliberately — you can't rescind an angel investment once accepted.

Types of angels

Operator angels (current or former founders/executives — highest signal). Sector angels (deep domain experience, valuable for intros). Financial angels (accredited investors treating startups as an asset class — least strategic value). Super-angels (writing $50-500K checks systematically, quasi-VCs).

Typical check sizes and terms

Individual check: $10K-100K typical, occasionally $500K+. Pre-seed rounds often composed of 10-30 angels. Standard instruments: SAFE post-money (US), convertible note (international, older investors). Valuation caps typically 15-30% higher than institutional pre-seed.

How to find angels

Warm intros from other founders (highest quality). AngelList profiles filtered by sector. Twitter/X (many angels announce publicly). LinkedIn search for "angel investor" + your sector. Alumni networks from your school or previous companies.

How to evaluate an angel

Backchannel two founders they've invested in. Ask specifically: "How responsive are they to questions?" "Have they made intros?" "Have they created any drama?" One difficult angel out of 20 is manageable; three difficult angels is a cap table nightmare.

Frequently asked questions

How many angels is too many?
20+ becomes hard to communicate with. 30+ requires structured investor updates and creates cap-table complexity. Consider an angel syndicate if you'd otherwise take many small checks.
Should we take a small check from a big-name angel?
Almost always yes. Even $5K from a well-known angel provides signaling value that dwarfs the check size.
How to say no to an angel who wants in?
"We've closed the round; happy to keep you posted for the next one." Direct and short. Angels turned away often become the next round's easiest close.
