Okay so the first customer was me, but still, I wanted to build a product that even I was willing to pay for!
In the next month I got my next two customers! I told my beta testers they could have the first 3 months for free (after we went into production), but one of them paid early! She also invited a friend, who converted after the 14 day trial! So pumped that my first customer was actually someone I didn't know 🎉
