Around 2011, 37signals switched from Interstate to Whitney for their company logo and the logos of their newly launched suite of services: Basecamp, Campfire, and Highrise.
The first 37signals logotype was designed by Carlos Segura using Interstate. The accompanying mark — which survives today — was designed by Ammon Haggerty.
