The First Money In

Angel investors are wealthy individuals who invest their own money (typically $25K-$250K) in early-stage startups in exchange for equity. They fill the gap between founder savings and institutional VC funding.

Who Are Angels?

  • Former founders: Exited their companies, now invest (e.g., Keith Rabois, Elad Gil)
  • Tech executives: Current/former C-suite at big tech (Google, Facebook execs)
  • Industry experts: Domain knowledge + capital (doctors investing in healthtech)
  • Professional angels: Full-time investors, 50-100 deals/year (Naval Ravikant, Jason Calacanis)

Typical Deal Structure

  • Check size: $25K-$100K per investor
  • Total round: $500K-$1M from 5-10 angels
  • Valuation: $2M-$5M post-money
  • Instrument: SAFE (Simple Agreement for Future Equity) or convertible note

Super Angels Era (2009-2012)

Twitter enabled professional angels to build brands and dealflow:

  • Naval Ravikant (@naval): AngelList founder, invested in Twitter, Uber
  • Ron Conway: Godfather of Silicon Valley, Google, Facebook, Airbnb
  • Chris Sacca (@sacca): Lowercase Capital, Twitter, Uber, Instagram
  • Dave Morin: Path founder, angel in dozens of unicorns
  • Keith Rabois: PayPal Mafia, angel then VC at Founders Fund

AngelList Revolution (2010)

Naval’s AngelList platform democratized angel investing via:

  • Online syndicates (pool money to invest together)
  • Searchable startup directory
  • Rolling funds (quarterly commits vs 10-year VC funds)

By 2020, anyone accredited ($200K income or $1M net worth) could angel invest via platforms.

The Risk-Reward

Reality: 50% of angel investments fail completely, 30% return 1-2x, 10% return 5-10x, 1-2% return 100x+. You need home runs to make money.

Tax benefits: QSBS (Qualified Small Business Stock) allows 0% capital gains tax on 10x+ returns if held 5+ years.
