We were very, very lucky being in the first round of Y Combinator because that alone generated a lot of interest. A lot of readers of Paul Graham were just excited to see what was going to come up. And we were the first ones to launch.

You know that Estonia, based largely on how successful Skype was, built by Estonian developers, that was a tenth of the entire country's GDP when eBay bought it. That was like a decade ago, it was f****** Estonia, they were behind the Iron Curtain two decades earlier. They're now pushing for K-12 education in computer science in public schools. They've gotten the message. They know how much value that can bring.

I often think of a quote from entrepreneur Jim Rohn: 'You are the average of the five people you spend the most time with.' Surround yourself with people who are doing interesting things, who are thinking interesting thoughts, who challenge you to be better, and who come from a diverse set of backgrounds and experiences. That, combined with appropriate moments of 'me' time, provides the perfect breeding ground for great ideas. And whatever you do, don't get hung up on what competitors are doing. Be aware of what's going on in the industry, but don't let it dictate your own creative process.

If you look now, more than ever new entrants, new upstarts, are able to grow so much faster than they could before.

Having ideas and doing them - that's what entrepreneurship comes down to. That's something that makes you not just a great founder who I want to invest in, but also a great employee or someone I want to work with.

The stage of investing that I do is seed stage, so it's really early. Here's a pair of founders who maybe have a prototype. They have a little bit of traction, maybe one employee, tops. At that stage, you really, really can only evaluate a company based on those founders and what they've been able to build. It's very, very team driven.
