Welcome to the Explorers Club

Greetings and Welcome Explorer,

I am glad that you found your way here. You deserve better than another routine day of drudgery aboard the Stellar Patrol Ship Feinstein. I think we want to work with you.

Detroit Labs is in the business of creating mobile apps. We do this by inviting the best and most interesting people to join our team, and asking them to solve the hard problems that go along with building and shipping software. Since you are reading this, you may be one of those people. I hope so!
