2014 - Highrise becomes a separate company to challenge SugarCRM

Early this year 37signals company announced that it's renaming from 37signals to Basecamp and slimming all product except one - Basecamp. Other products were going to be sold or spined off into stand-alone companies. So they decided to start with Highrise CRM - the second most popular app after Basecamp. Jason Fried, Basecamp CEO, says that they rejected a few deep-pocket buyers (including big software companies) because their plans included shuttering Highrise and rolling the customers into their existing product. At last they decided to spin off Highrise, so now it will run as its own company with its own CEO (Nathan Kontny), its own team, its own board, and its own budget (Highrise generates multi-million dollar annual profits). During the transition period, Highrise will lease some infrastructure and support agents from Basecamp, but ultimately it’ll be completely self-sufficient.
