Nick Weaver, the co-founder and CEO of high-growth start-up eero, has had to quickly learn a lot about launching and running a company. No lesson has been more important for him than letting go of the idea that he will know exactly what he's doing.

"The biggest message is accepting that you don't need to have all the answers," Weaver tells CNBC. "You have to be curious, and you have to always be willing to learn how to do something new or do something differently."

Weaver and his two Stanford buddies, Amos Schallich and Nate Hardison, launched eero in the summer of 2014. It's a San Francisco-based hardware company that makes devices to improve home WiFi. If you have ever tried to watch a movie on Netflix and your streaming has stopped ad infinitum to "buffer" the signal, then you know the problem that eero is trying to solve.

Since launching the company in Weaver's living room, eero has raised $90 million in venture capital. It has 115 employees and is selling on Amazon and in more than 600 Best Buy locations around the U.S.

Being at the helm of a rapidly growing start-up means that your role is always changing, says Weaver.

"My job changes dramatically from month to month," he says. As the company grows, "you are managing a bigger team, the team is working on more things, you have more customers, [and] you are expanding distribution to more retail customers."

"Things grow really, really quickly, and it's pretty challenging," he adds.

A popular in-house mantra at eero is "stays new, gets better." Once the eero device is in the consumer's home, Weaver wants it to continue to improve via software updates, even without the consumer buying a new piece of equipment.

That's the same philosophy he brings to being a start-up CEO: You have to constantly keep an open mind and listen to feedback in order to get better, Weaver says.

"The job just changes so much, so rapidly, that if you don't do that, it's hard to keep growing with the company."
