The Man Behind

David Kadavy is author of the #18 Amazon best-selling book, Design for Hackers: Reverse-Engineering Beauty. Prior to writing Design for Hackers, David founded the Design departments at two Silicon Valley startups, and freelanced for clients such as oDesk, PBworks, and UserVoice. David also launched numerous other projects on his own, none of which failed hard enough to be worthy of mention in this bio.

Since the debut of Design for Hackers, David has traveled the world, speaking about design and entrepreneurship, and mentoring startups, including those at 500 Startups.

David writes about Design, Productivity, and Entrepreneurship here, and has an awesome newsletter you can sign up for here (you’ll get free stuff if you do). He’s also very active on Twitter, so follow him.

Aside from writing and speaking about design, David is also an avid “Lifehacker,” and still gets all giddy when they cover one of his articles, or ask him How [He] Works.

David used to live in Silicon Valley, but he doesn’t anymore. Crazy, right? He left. I know. Yeah, we hear he’s hidden away on some street in Chicago lined with trees and brick buildings. Homeless? No, that’s not what we meant. He has a place. Also, when it gets too cold in Chicago, he usually runs off to South America for a couple of months.’s History has been around for awhile. David is so old that he still uses started as a bunch of Flash experiments that you can still find here. Nobody cares about them (or Flash, for that matter), but David insists that we keep them up.

The blog started on May 31, 2004 with this pointless blog post. I mean, it really sucks, doesn’t it? He even misspelled a word. Can you believe this guy wrote a book? What a joke!

How did that happen? Well, he just kept writing stuff. Like this one time he had a lump in his mouth and wrote about it, and it was so popular that an entire lump-mouthed community sprang out of it.

Then he was taking a shower one day (yeah, hot, right?) and he thought about 8 simple life hacks for health, wealth, and happiness, and that was the first time he had a post on Lifehacker.

Then he writes one stinkin’ blog post about design and gets a book deal. What a bunch of shit! I went to school for writing and here I am writing some friggen’ blogger’s about page. Where’s my book deal? on WPEngine has been hosted with numerous companies on numerous platforms, but is now happily served up on WPEngine. You can get a special deal on hosted WordPress if you use his special WPEngine free trial. They make it so damn easy. It’s great. No updating or getting hacked (knock on wood).

Saying “Kadavy”

It’s KAD-uh-VEE: “KAD” like “CAT,” “uh” like “duh,” “VEE” like “KNEE.” But, David’s not really too picky about what you call him, as long as it’s not “jerkface,” or something like that.

Common misspellings include cadavy, catavy, katavy, cadavey, and kadavey.
