Documented cause
Atrium paired proprietary legal software with a full-service law firm under one roof, but 200 employees serving just 450 clients at $500–$1,500/month produced a unit-economics hole that more funding could only deepen. When the co-founders acknowledged the absence of product-market fit, no lean pivot existed — the two-sided business model made selective retreat impossible.
Lesson
“Combining software margins with professional-services headcount inherits the worst unit economics of both worlds before it can harvest the best of either.”
