I worked on a diet/fitness gamification startup for 2 years. Built an iPhone app and a website with a fleshed out back-end. Spent around $50k of my own money for design, and coding help. Even built a list of 5000 users before launching, but it still didn’t work out at the end. Prior to that, I hacked on a site that helped you outsource your shopping. Toiled for a few years, spent close to $25k of my own money, and made maybe $1 in total income.
