At the core of many massive, profitable, global companies is an old idea executed exceptionally well. Facebook is just a better MySpace, and both are essentially digital meeting places. Taxis take people from point A to point B. Uber/Lyft just figured out how to make this service more convenient. None of these are billion-dollar ideas; rather, they’re billion-dollar executions of ideas. That’s why companies of one shouldn’t worry about sharing their ideas, as long as they’re taking care of execution and their ideas are not proprietary.
