The half-life of companies is shrinking. So in the same ease in which you can start a company today to disrupt an incumbent, you have to also realize that somebody will do that to you as well just as easily. So if you're not just going to get on top but stay on top, that will require a real prepared mind across many companies.

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.

As you start the company, you start spending spending spending ahead of revenue but then you come out of it and very quickly you should become a company that spends less than it makes. And what I mean by very quickly, is that window of time should be in that 6 to 8 year time frame. And the reason is because if you build your business model correctly it's almost unavoidable.

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.

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 going public should not be a goal and the more that we make it a goal, the less it will be a goal. It's kind of like, I have three young children and when I tell them to eat vegetables, the last thing they will ever do is eat vegetables. I think it's just this weird thing where entrepreneurs have a reflexive negative reaction when people are pushing for it. I think you have to view going public for what it is, which is a transitional moment where you can consolidate mindshare and win at an even larger scale.

If you're trying to get to profitability by lowering costs as a startup then you are in a very precarious and difficult position. You need to grow through profitability.
