Interesting you avoided calling them basecamp given the recent media fallout. Not saying you did it intentionally, but just rare anyone refers to them as 37Signals much anymore.
I forgot they had changed their name. They were 37Signals when they were HN's darling. This is the company everyone was in love with: https://37signals.com/manifesto
Eh it’s still how I think of them, fwiw. I haven’t seen as much from them since their name change.
It was my impression Basecamp is more associated with the product of the same name, rather than the group (37signals) associated with it. Correct me if I'm wrong, others may have a different opinion and I'm not the foremost expert on that.
They formerly renamed the company to Basecamp a few years ago and shut down / spun off other products (campfire and highrise).
