Source-derived summary

37signals (formerly Basecamp before reverting to its original name) is an American web software company based in Chicago, Illinois. The firm was co‑founded in 1999 by Jason Fried, Carlos Segura, and Ernest Kim as a web design company.

Since mid‑2004, the company's focus has shifted from web design to web application development. Its first commercial application was Basecamp, followed by Backpack, Campfire, and Highrise. The open source web application framework Ruby on Rails was initially created by David Heinemeier Hansson for internal use at 37signals, before being publicly released in 2004.

In February 2014, the company adopted a new strategy, focusing entirely on its flagship product, the software package also named Basecamp, and renaming the company from 37signals to Basecamp. Jason Fried and David Heinemeier Hansson have published several books under the 37signals name, and in May 2022, citing their present-day focus on both Basecamp and HEY, reverted to 37signals as their company name.

History

The company 37signals was originally named after the 37 extraterrestrial radio signals identified by astronomer Paul Horowitz as potential messages from extraterrestrial intelligence. Work on the company's first product, the project management application Basecamp, began in 2003.

By 2005, the company had moved away from consulting work to focus exclusively on its own web applications.

Editorial analysis

Why this record matters

The phrase “american business” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q2364173. VIAF identifies the subject as 155120605. The Library of Congress control number is no2004023968. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1999, 2004, 2014 and 2022.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
