The course aims to create thoughtful angel investors who make informed decisions and build better relationships with the companies they invest in, and I invest when I get excited about a company, believing I can always help because I've seen so many companies over my thirteen years of angel investing.

Angel investors are individuals who invest their personal money in early-stage startups, typically writing smaller checks and often engaging in this as a side project rather than a full-time job.

Angels are typically wealthy individuals investing their own money, while VCs invest other people's money and have a different decision-making process.

Angel investors use their personal funds to invest in startups in exchange for equity, typically after the business has some validation but before it's ready for venture capital.

Even amateur angel investors can approach investing professionally by being organized, thinking about their portfolios, and recognizing that it's a long-term game.

It's important for new angel investors to meet with many founders and companies to make educated judgments about investments.

Understanding the investor's perspective is crucial; angel investors and venture capitalists have different priorities and expectations.

The goal of Investor School is to share knowledge from Y Combinator to help people become effective angel investors and avoid common pitfalls.
