37signals

37signals is the company behind Basecamp, HEY, and ONCE — tools built to be simple, opinionated, and profitable without venture capital. Founded by Jason Fried and David Heinemeier Hansson, the company has been a pioneer of remote work, calm company culture, and sustainable business practices since 1999. With a team of roughly 80 people and zero outside investors, 37signals distributes 10% of annual profits directly to employees. They pay top-of-market salaries regardless of location, cap the workweek at 40 hours, and offer paid sabbaticals. Their philosophy: great work comes from small teams, clear thinking, and treating people well.
