An investor explains why he only backs founders who have sold something, even a lemonade stand. Selling teaches you to handle rejection and understand customers. Many tech founders skip this step and fail because they can't acquire customers.
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 to 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.
