Student transportation startup Zum raises $130 million

• It's also a massive expense for school districts, second only to salaries. Zum is seeking to help in both areas, by reducing inefficiencies that can result in half-empty busses taking roundabout routes.

In addition to the technology, Zum provides several sizes of vehicles, from buses to vans and cars, and is moving toward having an all-electric fleet." — Cromwell Schubarth, SV Business Journal
