What Is Angel Investing?

Writing checks with your own money

An angel investor is an individual who invests their own capital directly into early-stage private companies, usually in exchange for equity. The word "angel" is inherited from Broadway, where wealthy patrons funded shows that couldn't get bank financing; the modern usage is the same idea applied to startups that are too early, too small, or too unproven for institutional capital. A typical angel check runs from $10,000 to $250,000, though both ends of that range stretch further depending on the investor and the deal.

What makes this a genuinely different job from venture capital or private equity isn't the size of the check, it's whose money it is. A VC or PE professional is deploying other people's capital: limited partners (LPs) who committed money to a fund, expecting it managed according to a mandate, reported on quarterly, and eventually returned with a profit. An angel is deploying their own. That single difference removes an entire layer of obligations, and replaces it with a different set of constraints.

What disappears, and what stays

No LPs means no fundraising cycle, no fund documents, no quarterly reporting, no management fee to justify, and no fund-level reserves math to plan around (Lesson 21 covers the individual-angel version of "saving capital for winners," which looks nothing like a fund's reserve model). There's also no carry, the 20% of profits a fund manager typically keeps as compensation, because there's no outside capital to be compensated for managing. Every dollar of return is the angel's own.

What doesn't disappear is the hard part: real due diligence, real judgment about founders and markets, and real portfolio-construction tradeoffs. If anything, a solo angel has less time, less specialized staff, and less negotiating leverage than a fund to do that work with, which is exactly why the rest of this course spends so much time on how to do diligence and construct a portfolio efficiently as one person, not a team.

What this course covers

This course follows the same backbone as the site's Venture Capital course, because the mechanics genuinely overlap: SAFEs, cap tables, term sheets, and the power-law return distribution all work the same way whether the check comes from a fund or a checkbook. What changes throughout is the seat you're sitting in: sourcing without a fund's brand (Lesson 10), negotiating without a fund's leverage (Lesson 18), and building a portfolio without a fund's reserves formula (Lessons 20-21). By Lesson 35, you'll work through a full deal evaluation from first look to a real decision.
