Eulogy
Justin Kan founded Atrium in 2017 to do to legal services what software had done to everything else: a law firm with real engineers, better tooling, and startups as clients. It raised $75.5 million. On 3 March 2020 it shut down, laid off just over 100 people, and returned some capital to investors including Series B lead Andreessen Horowitz. The affiliated law firm carried on without the software company. Kan's own summary afterwards was blunt: don't build a services company.
Lessons for the living
The founder's own postmortem: don't build a services company. Software margins don't survive contact with billable hours.
