Angels are individuals who invest their own money — usually $10K–$250K per check. They move faster than VCs and are often the first money in.
Where to find them: AngelList, your network, customers. Best angels are operators in your industry — they bring intros and pattern-recognition.
Treat them like co-founders. Update them monthly.
