Zum extends CMX across LAUSD's in-house school bus fleet

Why it matters

LAUSD gives Zum a large-scale test of its software strategy: selling one coordination platform across district-owned and contractor-operated buses without requiring Zum to operate the entire fleet.

Ritu Narayan is turning Zum, the student transportation company she founded with her brothers, into the software layer connecting vehicles that Zum does and does not run. On September 22nd, Zum said Los Angeles Unified School District had begun deploying its CMX platform across the district's in-house bus fleet for the 2026-27 school year.

Zum's 2026-27 deployment extends CMX across LAUSD's district-operated buses, creating one technology layer across district- and Zum-operated vehicles. LAUSD's modernization materials say the upgrade includes GPS equipment, interior and exterior cameras, driver tablets, passenger counters and student ID scanners. Beginning in August 2026, students who ride district buses are expected to scan school-issued IDs when boarding and leaving, while families can follow bus locations through LAUSD's parent applications.

Zum describes CMX as an AI-powered operating system connecting routing, dispatch, drivers, schools, families, safety and fleet operations in real time. Drivers receive digital routes, navigation and live updates, while dispatchers get a common view of buses operated by Zum and LAUSD.

Narayan built Zum with her brothers, chief operating officer Vivek Garg and chief technology officer Abhishek Garg, after encountering the transportation problem as a working parent. She was an eBay product executive when unreliable rides for her two children repeatedly threatened to pull her away from her career, TechCrunch reported. Her mother had left an education career in India to raise four children, giving Narayan an earlier example of how care and transportation gaps can narrow a parent's choices.

Zum began with scheduled rides for individual families before concentrating on full-service district contracts. The LAUSD deployment carries that strategy one step further: Zum can sell the coordination layer even when district employees operate the vehicles.

The public contract is worth up to $20.8 million

LAUSD's board records identify Zum Services, Inc. as the contractor for a transportation management system covering GPS, routing, dispatch, cameras, student tracking, fleet diagnostics, hardware and software, with a five-year aggregate value of $20,791,648. The contract runs from June 5th, 2024 through June 4th, 2029 and includes two optional one-year extensions.

The procurement drew 11 proposals, according to the board materials. Four bidders qualified, and LAUSD identified Zum as the highest-rated proposer after evaluating technical approach, price and a product demonstration. The district also cited Zum's previous work with Oakland Unified, San Francisco Unified and Seattle Public Schools.

The Associated Press identified LAUSD as operating the country's second-largest school-bus fleet, behind New York City. LAUSD's 2024 sustainability report states that the district operates two vehicle fleets and that its Yellow Fleet consists of 1,300 school buses. Zum has not specified how many district vehicles have received CMX hardware and software so far, or provided a schedule for completing the deployment.

Abhishek Garg said the unified platform would give transportation staff "greater visibility, coordination and accountability." The harder task is making that visibility useful during the morning rush, when route changes, absent drivers, traffic and late student additions collide.

TPG's $100 million bet is moving into production

The LAUSD expansion follows a large financing built around the same strategy. On April 16th, Redwood City, California-based Zum announced a $100 million investment from TPG's Rise Funds. Zum said the transaction brought total funding to $430 million and valued Zum at $1.7 billion. TPG joined backers including GIC, Sequoia Capital, SoftBank and Spark Capital.

That financing followed a $140 million Series E announced in January 2024, led by GIC with participation from Climate Investment, Sequoia and SoftBank Vision Fund 2. Zum said that round valued it at $1.3 billion and brought total funding to $350 million. Fortune reported the following month that Zum had about 2,000 employees and served 4,000 US schools at the time.

Zum said the TPG money would fund CMX expansion, AI-driven coordination and infrastructure for large transportation systems. Extending the platform across LAUSD's own fleet is a direct use of that capital and a valuable reference deployment for selling software independently from operated transportation services.

Selling CMX into vehicles a district already operates gives Zum a path to software revenue without taking over every route. Zum has not broken out the share of its revenue generated by CMX software versus transportation operations, leaving investors without a clear measure of how far Zum has moved toward the software model.

That hybrid approach places Zum alongside several kinds of vendors. Via markets routing, GPS tracking and caregiver applications to districts operating existing fleets, while BusRight sells routing and driver-navigation software. Zum's pitch is that the same provider can operate contracted transportation and supply the coordination system used by a district's own buses.

Zum now says CMX serves more than 6,500 schools across 19 states. In April, Zum reported 4,500 schools in 17 states. The increase may include newly contracted schools, broader CMX deployments within existing districts or a change in how Zum counts coverage. Zum has not explained the difference.

Reliability remains the test

In an August 13th release, Zum said it averaged 98% on-time performance and had earned a 4.9 out of 5 parent rating across more than 1.7 million ratings. Those are company-supplied figures, and individual launches can produce a different result.

In August, KCTV reported complaints about late buses and tracking problems during Zum's first week operating in Kansas' Shawnee Mission School District. Zum acknowledged delays and said its on-time rates at that point were 98% for high school routes, 85% for elementary routes and 83% for middle school routes. Zum attributed the disruption partly to a three-tier bell schedule and 688 students being added after the school year began, then added routes and drivers.

The Kansas episode is separate from the LAUSD deployment, yet it shows the standard CMX must meet. A shared dashboard has limited value when parents cannot trust its location data or dispatchers cannot turn its alerts into an on-time bus.

Narayan started Zum to give parents certainty about a daily task that had become an obstacle to work. LAUSD is a larger version of that founding problem: hundreds of routes, multiple operators and a district-owned fleet. LAUSD's 2020 routing request identified MapNet as its routing software and said several other applications interfaced with it to support student transportation. Connecting those pieces through CMX gives Zum a chance to prove that its technology can coordinate a public transportation network without owning every bus inside it.
