An AI-backed electric school bus service running privatised school bus fleets with route optimisation and parent tracking.

Serving all 25 million-plus US students who ride school buses as districts' fleet operator beat a consumer ride-hailing service for individual families.

Product manager Ritu Narayan founded Zum in 2015 after her own children's school rides kept failing at pickup time — the same problem that had pushed her mother, a teacher in India, out of her career decades earlier.

Zum launched as a self-funded Uber-for-kids and caught on quickly with Bay Area parents. In 2019 schools offered to hand Zum their bus operation instead; Narayan took about eight months to decide, torn between the founding mission and the larger market, and took the risk.

The district market was an order of magnitude larger than direct-to-parent rides.

Fleet contracts meant recurring infrastructure revenue instead of one ride at a time.

Electric vehicles and tracking technology differentiated Zum from incumbent bus operators.

The founding mission transferred intact: the same children and parents, served at system scale.

When a bigger customer asks you to become their infrastructure, the founding story will fight the pivot — decide by who you still serve, not what you used to sell.

As of the February 2024 interview, Zum reported $1.5 billion in school contracts and a $1.3 billion valuation; both figures are self-reported by Narayan in the interview.
