1. What is Angel Investing?
Angel investing involves providing early-stage funding to startups in exchange for equity (ownership in the company). Unlike venture capitalists, angel investors typically invest their own money rather than managing external funds.
✔ Investment Amount: Ranges from $10,000 to $500,000+ per startup.
✔ Goal: Support high-growth startups and earn 10x+ returns if the company succeeds.
✔ Risk Factor: 90% of startups fail, so thorough evaluation is critical.

Track Record: Have they successfully built businesses before?

A startup must have a competitive edge to succeed.

Break-even Point: When will they become profitable?
❌ Red Flag: High burn rate & no clear path to profitability.

Acquisition Potential: Are big companies interested in this market?
IPO Potential: Could this startup eventually go public?
