An investor explains why he looks for founders who've sold something, even a lemonade stand. Sales teaches you to handle rejection and understand what customers actually want, skills most tech founders lack.
Even as an investor today, one of my litmus tests when I get pitched by a founder is, have you ever sold anything in your life? I don't care if it's a lemonade stand or in college you had a hustle. If you haven't put yourself out there, you haven't been rejected, you don't really know what it's like. And too many tech founders don't have that skill and aren't successful, even if they're building the very best thing that you can possibly imagine.
