An angel investor is a high-net-worth individual who invests personal funds into early-stage companies, usually accepting high risk for potential outsized returns and strategic involvement.

How it works

Angels invest via SAFEs, convertible notes, or priced seed rounds—often alongside other angels in a rolling close. Many are former founders or operators investing in sectors they know. They may join as advisors, make customer intros, or syndicate co-investors through platforms.

Regulation requires most angels to be accredited investors in U.S. private offerings. Angels differ from VCs, who invest other people’s money from a fund with a formal LP structure and fee model.

Why it matters

• Founders: Curate angels for additive skills, not just logos. Cap table hygiene matters—too many small angels slows future rounds.
• Investors: Angel performance is portfolio-style; many bets, few winners. Syndicate leads scale angel economics with carry.
• Operators: Some angels take board observer seats; most stay informal mentors.

Common mistake

Taking every willing angel without checking value-add or signaling risk. A crowded angel cap table with unknown names can scare institutional leads.
