School Bus Unicorn Zum Notches $333 Million in Revenue

Zum Services Inc., a tech company that provides bus and transit technology to more than 4,000 schools, says it hit $333 million in revenue for 2025, up 35% from the year before.

The company’s platform helps route school buses and aims to make them run more efficiently. It also hires drivers and in some instances builds out electric bus fleets itself. As the company grows, it’s hoping to add more customers and eventually go public.
