I am the creator of Ruby on Rails, founder & CTO at Basecamp (formerly 37signals), best-selling author, Le Mans class-winning racing driver, public speaker, hobbyist photographer, and family man.

I tweet from @dhh and email from david@heinemeierhansson.com.

I write essays on Medium (via Signal vs Noise) and this site.

I share pictures on Instagram.

Creator of Ruby on Rails

Ruby on Rails is an open-source web framework that's optimized for programmer happiness and beautiful code. I created Rails in 2003 by extracting it from Basecamp and continue to lead the development.

Hundreds of thousands of programmers around the world have built amazing applications using Rails. Some of the more famous include Twitter, Shopify, 500px, and Github.

Founder & CTO at Basecamp

Basecamp is the world's #1 project management tool and has been used by more than 15 million people. It's the best way to make progress on projects together, and it's famously easy to use. We've been around for more than a decade. I run the company together with my business partner, Jason Fried, and our lovely team of 48 programmers, designers, supporters, and sysops.

We've just released an all-new version 3 that we're mighty excited about. Give it a look.

(We were formerly known as 37signals, but changed the name of the business in 2014.)

Best-selling author

REWORK is a New York Times, Wall Street Journal, and Sunday Times best seller with more than 300,000 copies sold around the world. It's a book about starting and running businesses a better way.

REMOTE: Office Not Required encapsulates all I've learned about working remotely for the past decade. It includes all the arguments for why the time is right for remote work to blossom, and for how you can navigate the pitfalls. It's in the same style as REWORK: Short, wonderfully illustrated, and to the point.

I also co-wrote Getting Real, the predecessor to REWORK, and Agile Web Development with Rails.

Finally, I've authored a couple of #1 Medium posts that you might also like: RECONSIDER, about the Unicorn-hysteria in the startup world, and The day I became a millionaire, about, well, becoming a millionaire!

Le Mans & WEC class-winning racing driver

After climbing the ladders of racing for five years, I won my class in the 82nd running of world's biggest endurance race: 24 hours of Le Mans. On top of that, I won my class in the World Endurance Championship. What a 2014 season!

This all happened with the wonderful Aston Martin Racing (Young Driver) team in our #95 Vantage V8 GTE-AM car, also known as "The Dane Train" (due to our all Danish driver line-up) together with drivers Kristian Poulsen and Nicki Thiim and team owner Jan Struve.

Aston Martin #95

In 2016, I'll contest my fifth season in WEC and at Le Mans in a Porsche 911 RSR with Abu Dhabi Proton in GTE-AM. I'll be driving alongside Patrick Long and Khaled Al Qubaisi. We start the season at the 6 hours of Silverstone in April.

ESM Racing HPD LMP2 car

In 2012, 2013, and 2015, I also drove in the WEC, but in the LMP2 class. I finished 2nd at Le Mans, 2nd in the championship in 2013 with OAK Racing driving alongside Alex Brundle and Oliver Pla.

As of 2015, I've won 4 races and been on the podium 15 times in the WEC. Additionally, I've finished on the podium three times at the 12 hours of Sebring and taken two class wins in the LMP2 class in the 2012 ALMS season.

I tweet about racing from @dhhracing.

Public speaker

I occasionally give talks on business and technology. My most popular talk is The Secret To Making Money Online, delivered at Startup School in 2008. It's about how you don't need to aim to be a billionaire or take lots of venture capital to have a successful startup (and life):

Along the same lines, I debated Jason Calcanis from This Week in Startups on business models, bubbles, capitalism, quality of life, market share vs. profit share, running a business vs. selling a business, and a variety of other related topics (fast-forward 47 minutes):

See also the follow-up debate with Calcanis from 2013 where we revisit some of the same topics as well as new ones. That same year, I told Stanford Business School how to Unlearn Your MBA.

I usually deliver the opening keynote at RailsConf every year as well.
