The Lede
A meeting gets cancelled. A company gets born.
The morning Ritu Narayan's calendar caved in for the third time in a week, the culprit wasn't a deadline. It was a school bus that didn't show. She was a Group Product Manager at eBay then. Two kids, dual career, the usual Bay Area juggle. The bus was decades-old technology run by hundreds of mom-and-pop operators on paper schedules, and when it slipped, her day went with it. She thought of her own mother, a teacher in India who had eventually walked away from the classroom to manage the same problem from the other side. The math hadn't moved in forty years.
Narayan spent fifteen years inside the engines of the consumer internet - IBM, Oracle, Yahoo, eBay - shipping product for places where reliability was a baseline expectation. She knew what an SLA felt like. She also knew that 27 million American children take this ride twice a day on a system that has no software layer worth the name. The arithmetic of a $50 billion market with no winners is not subtle. In 2015 she left eBay and started Zūm.
The first version was a concierge service. Vetted drivers, an app, parents who would pay for sanity. It worked. It also wasn't the business. In 2019 she walked into a handful of school districts hoping they would tell parents about her. The districts had a counter-offer: take over our buses. They were tired of the diesel, the no-shows, the missing data. Within weeks Zūm pivoted from a B2C ride service into the country's most aggressive school-bus operator. It is the rare founder who hears "you are doing the wrong thing" from a customer and ships the right thing by the next semester.
Today Zūm runs across more than 4,000 schools. Its electric buses serve Oakland Unified - the first US district to operate a fully electric school bus fleet - and the buses don't just move kids. When they park, they push power back into the grid through vehicle-to-grid hardware, turning a depreciating yellow asset into a distributed energy resource that pays the district. The boring bus, it turns out, is a battery on wheels with 180 stops a day.

The Long Arc
From PM to fleet operator, by way of not waiting.
If you draw the line through Narayan's career it isn't a vertical climb. It's a turn. She spent the 2000s inside large product orgs learning the discipline of consumer software at scale - the rituals of A/B testing, the patience of platform thinking, the politics of shipping. She finished a Sloan Fellowship at Stanford GSB while still inside that world. Then she left, and the company she chose to build did not look like anything she had ever shipped. School transportation is hardware, labor, regulation, weather, and a parent's patience, all on the same Tuesday morning.
The product instinct stayed. Zūm's interface is a parent app, a driver app, a dispatcher dashboard, and a district analytics layer. It is built like a B2B2C SaaS product on top of a logistics company. The technology stack reads more like a consumer internet startup than a school-bus operator - React on the frontend, Looker for analytics, Salesforce on the customer side, Amazon Kinesis moving telemetry off the buses, Geotab and Fleetio for the fleet, ChatGPT and Claude on the AI side. None of this was true of the school-bus industry in 2015. Most of it isn't true of the school-bus industry now, either. Zūm is the exception that is trying to become the rule.
The electrification thesis arrived in 2021, when the federal government began funding clean school buses at scale and California utilities began paying for grid-connected battery capacity. Most operators saw electric buses as a cost problem. Narayan saw a balance-sheet problem - one she could solve by turning every parked bus into a sellable kilowatt-hour. Oakland Unified became the proving ground. 74 electric buses. Vehicle-to-grid in production. The first district fleet of its kind in the country.
Her board-room argument since has been a quietly radical one. Run the math on a district that owns a fleet, and you find a $1M-per-school energy asset hiding in the parking lot every afternoon. Zūm's pitch is not "buy electric buses." It is "let us run them, and we'll send you a check from the grid."

Scrapbook
Three clippings from the cutting room floor.
The kitchen-table founding
The idea did not arrive at a board offsite. It arrived on a weekday at home, after a third bus failed to come, with a meeting waiting. The fix she would have wanted as a parent became the company she would build for other parents.
"Take over the buses"
She walked into school districts in 2019 with marketing in mind. The districts handed her the keys to their fleets instead. The pivot from concierge rides to bus operator happened in weeks.
Battery on wheels
Oakland's Zūm buses send energy back to the grid when parked. The yellow bus, recast as a distributed power plant that goes home at 3pm.

The Argument
Why student transportation is climate tech.
The Fleet
About 480,000 school buses operate in the US, more than every other form of mass transit combined. Most still run on diesel. Replacing them is the single biggest electrification opportunity hiding inside the education budget.
The Grid
School buses are parked from mid-afternoon until early morning, and all summer. That is exactly when utilities need stored energy. Vehicle-to-grid technology turns each bus into a 100+ kWh battery that earns its keep.
The Kids
The pitch only works if the ride still works. Real-time tracking for parents, RFID attendance, route optimization, driver scoring - the software stack exists so the headline can stay simple: the kid got there.
Our mission is to make student transportation safe, reliable and equitable for every child, family, driver and school.- Ritu Narayan, on Zūm's purpose
