Today, Feb. 5, 2014, is an important day for the popular Web application company 37signals. Not only does today mark the 15th anniversary of 37signals, but it also brings about a rebranding of the company.

Henceforth, 37signals shall be known as Basecamp, effectively having the same name as its popular project management tool. The rebranding is actually in line with 37signals’ refocusing as a one-product company. And that product is, of course, Basecamp.

Basecamp (formerly 37signals) founding CEO Jason Fried states in his announcement on the 37signals homepage:

We’re changing our name. 37signals is now Basecamp. “37signals” goes into the history books. From now on, we are Basecamp. Basecamp the company, Basecamp the product. We’re one and the same.

Consequently, 37signals’ iOS apps are now listed in the App Store under the developer name Basecamp. These apps include the official Basecamp app, the group chat app Campfire, and the contact manager Highrise.

But what happens to Campfire and Highrise now that Basecamp stands front and center? According to Fried, while the exact fate of these two services is yet uncertain, they will continue to operate normally in the short term.

Optimized for iPhone and iPod touch, Basecamp, Campfire, and Highrise are all available in the App Store for free.
