It is every entrepreneur’s dream: start a company, obtain millions of users, and then sell your company to Facebook for a cool $1 billion.

As you may know by now, that Cinderella story belongs to Instagram, the photo sharing app loved by over 30 million people. Say what you want about the company not having a business model, zero revenue, etc. The reality is that internet companies are not defined solely by how much money they’ve made so much as they are by their user base.

I was on Hacker News and I came across this video (embedded below) of a talk that Instagram Co-Founders Kevin Systrom and Mike Krieger gave at Stanford, months after launching their app. It doesn’t take very long to realize how ridiculously smart these two individuals are as they explain some of the things they’ve learned from their entrepreneurial experiences. Check out the video and see for yourself.
