Bootstrapping allows you total creative freedom. For example, if you decide to approach your business in a certain way that makes it a two- or three-year process to get to your first product, you can do that, versus being rushed into it by investors.

In France, a hip replacement was captured using two GoPros in a stereoscopic 3D arrangement. Students can watch the surgery using a virtual reality headset.

My friends used to tease me 'cause I'd wear a CamelBak while I was working so I wouldn't have to get up if I was thirsty.

To get GoPro started, I moved back in with my parents and went to work seven days a week, 20 hours a day. I wrote off my personal life to make headway on it.

Dedicating myself to actually following through was my single biggest achievement.

I come into work late morning time and go at it until early evening, and I'm lucky that I'm at the point where I'm able to do that.

People are watching GoPro content not to decide whether they should buy it or not - they're watching it for the entertainment.

People don't go buy GoPro for the thing; they buy it for what the thing does.

A smartphone is a mobile computer in your pocket.

Viral word-of-mouth marketing for GoPro is massive. Video is really the conduit.

At Warby Parker, we ask ourselves a number of questions when deciding whether or not to partner up with a designer, or a nonprofit or brand. Is the potential collaboration new? Is it unexpected?

Asking for money can be especially intimidating.

If you don't plan to dive in and dedicate all of your time to your startup, you probably shouldn't be looking for funding. It's hard enough asking for money when you believe in an idea; asking for money to fund something you're iffy about is ten times more strenuous.

At the end of the day, an entrepreneurial journey is all about de-risking: How can you spend the least amount of time and money to accomplish your goal? The more information you can gather, the more comfortable you'll be investing time and money into a particular offering.

During times of plenty - when venture funding is abundant and startups multiply like rabbits - every business looks like a winner.

Regardless of what you plan to use it for, the goal should always be to raise money right before you need it. You don't want to get into a situation where you need cash and you're unable to raise it - or you're unable to raise it on favorable terms.

We've built our own technology platform in-house, which operates our website and powers our retail stores.

No matter what product or service your company offers, people have a way of finding out if you are genuinely providing value.

I previously worked as the director of VisionSpring, a non-profit dedicated to distributing glasses to people in need.
