Nothing. I haven’t built anything with a significant impact. I’ve made things that made a significant impact on businesses, but in the scheme of things, nothing exciting.

The thing I made which generated the most revenue was easily the most harmful, and likely the most impactful. Unfortunately. It was an ad exchange that did extremely well. The owners went from random guys with a gross idea to multimillionaires in a couple years. They both spend their days buying up startups.

I should have done better by now. I feel like I need to make up for building that exchange. I was young and had no idea what I was getting into until it was too late.
