Building a magical AI code editor used by over 1m developers in 4 months: Inside Windsurf

(instrumental music) A lot of the bets we're making inside the company are for things that are not, you know, three, four weeks away. We should be cannibalizing the existing state of our product every six to 12 months. Every six to 12 months, it should make our existing product look silly. It should almost make the form factor of our existing product look dumb.

How do you know when it's time to hire someone?

I wanted the company to almost be like this dehydrated entity. Every hire is, is like a little bit of water, and we only go back and hire someone when we're back to being dehydrated.

Any other skills you think people should be investing more in with the rise of AI building more and more of our products?

The engineers are now able to produce more technology. The ROI of building technology has actually gone up. This actually means you hire more. The best thing to do is just get your hands dirty with all of these products. You could be a force multiplier to your organization in ways in which they never even anticipated.

(instrumental music) Today, my guest is Varun Mohan. Varun is the co-founder and CEO of Windsurf, which has quickly become one of people's favorite AI coding tools, and is basically the main competitor to Cursor, with over one million users four months in. In our conversation, Varun shares what makes Windsurf unique, why they decided to invest heavily in enterprise sales very early in their history, why agency is gonna be the most important skill for engineers and product builders to build. Also, the story of how they started out as a GPU infrastructure company and realized there was a much bigger opportunity up the stack, and the two pivots that got them to where they are today. He also gives a live demo, advice for being successful at Windsurf, and so much more. There's so much to learn about where things are heading for engineers and product builders in general in this conversation, and I'm really excited to bring it to you.
