What separates the businesses that get funded from the ones that don’t?

Angela Lee, a professor at Columbia Business School and founder of 37 Angels, has helped evaluate over 20,000 startups and knows exactly what makes investors say yes.

In this episode, Angela breaks down how to think like an investor, what metrics actually matter (hint: it’s not just revenue), and how to turn early traction into long-term growth. She shares practical frameworks – from the “triple, triple, double” growth model to scrappy experiments like landing page testing – that can help you validate your idea and scale with intention.

If you want to stop guessing what investors are looking for – and start building a business they can’t ignore – this episode is for you.
