I think the reality is that it's never been a better time to be an entrepreneur, it's never been a better time to work at a startup. You work at a really intellectually free environment, you get to work with people who are like-minded, it's very energetic. It's wonderful.

I think unfortunately in this gold rush mentality that we've been in for the last years there has been not enough focus on business model quality. So when push comes to shove, there actually aren't that many great businesses that can go public. Because I think if you're going to thrive as a public company, it presupposes that you make more money than you spend.

The point of Silicon Valley at least when I moved here was we're all trying to do stuff and none of us quite felt like we fit in anywhere else. But we were all trying to do good things. And the money was just the byproduct of good things. The idea that there's an obligation to have that thing happen in four years or five years or six years, I think we need to disavow that.

If you look at the ecosystem, entrepreneurs as a class have gotten younger, younger, and younger. They also as a class have become less and less and less experienced. The good part about that is that you're unlocking this ability to start a company to so many more people. That's an amazing positive. The negative is they're coming to that job with dramatically less experience than they've ever had. So there needs to be someone around the table that can then help them.

The reason to go public is that it is a massive branding, marketing, credibility, trust-building exercise with your customers, and then it allows you to consolidate power and scale and market share. Do we want to be a huge company with a huge impact? If the answer to that is yes, the only way that that happens is by going public. It is effectively a branding event that catalyzes interest. It helps with recruiting, it helps with marketing, it helps with sales. It just helps on many dimensions. I think it's basically a litmus test for the CEO's ambition.

I think the reality is that it's never been a better time to be an entrepreneur, it's never been a better time to work at a startup. You work at a really intellectually free environment, you get to work with people who are like-minded, it's very energetic. It's wonderful.

I would tell startups to just keep your head down, keep building. Your contingency plan, if you have one, should be because you are still spending more than you make and you still don't have a line of sight for that J curve. That is the most important contingency. Because otherwise you are betraying that equation to your cofounders, to your investors, to your employees and to your customers.
