Israeli-founded AI-native software for public-transit planning. Amos Haggiag and Eitan Yanovsky, 2014. Bessemer/Insight/Tencent $107M Series C 2021 unicorn round; Series D $100M 2022 at $2B. Deployed across 5,000+ cities. Electrification tailwind.
Optibus is an Israeli-founded software platform that public-transit operators use to plan, schedule, and manage bus and rail networks. Its product replaces the spreadsheet-and-legacy-software workflow that has historically governed how a city decides which buses go where, at what time, driven by whom — a workflow whose inefficiency, at scale, is one of the largest hidden cost centers in public transportation globally. Optibus applies optimization algorithms and increasingly machine-learning models to that workflow and produces measurable reductions in operating cost, fuel consumption, and driver overtime.
The company was founded in 2014 by Amos Haggiag and Eitan Yanovsky, and is headquartered in Tel Aviv with regional offices across the U.S., U.K., Latin America, and Asia. Optibus reached unicorn valuation in May 2021 on a $107 million Series C led by Bessemer Venture Partners, Insight Partners, and Tencent — the round that formally established the category of AI-native public-transit planning software.
What the product actually does
Every day, a public-transit agency has to answer a series of questions that look simple and are not. Which vehicles will run which routes tomorrow? How do we sequence the routes so buses spend minimum time deadheading between them? Which driver is assigned to which shift, given union rules, mandatory breaks, seniority preferences, and skill requirements? What happens when a bus breaks down at 4:47 p.m. on a Tuesday during rush hour?
The traditional answer runs through legacy scheduling software developed in the 1980s and 1990s, layered on Excel and heuristic rules of thumb. Optibus's answer runs through a modern optimization engine that treats the network — routes, vehicles, drivers, depot capacity, regulatory constraints — as a single combinatorial problem and solves it in minutes rather than days. The measured result across operator deployments is meaningful reductions in vehicle miles, fuel consumption, and overtime pay.
The founders
Amos Haggiag — CEO and co-founder. Prior background in AI research and enterprise software; entered public transportation after concluding, through direct research, that the sector's software layer was one of the largest under-modernized commercial-technology markets globally.
Eitan Yanovsky — CTO and co-founder. Longtime Israeli engineering leader who built the original optimization engine and continues to run product architecture.
The founders' choice of public transit as their target category is unusual. Most Israeli founders of their generation with backgrounds in optimization and machine learning went into advertising technology, cybersecurity, or fintech. Optibus is one of the more prominent examples of Israeli engineering talent applied to legacy government-adjacent infrastructure.
Technology depth
Optibus's core is a set of combinatorial-optimization solvers tuned to the specific structural shape of public-transit scheduling problems. That shape is unusual in optimization terms. Route planning, vehicle scheduling, and crew scheduling are historically treated as three separate problems, each with its own solver. Optibus solves them jointly, which produces meaningfully better plans than pipeline architectures that solve them sequentially.
A second dimension is real-time adjustment. Static plans are one product surface; a separate product surface handles the day-of operations — vehicle breakdowns, driver call-outs, weather disruptions, traffic. The real-time layer runs against the same underlying solver infrastructure.
The third dimension is electrification. As transit agencies globally transition their bus fleets from diesel to electric, the planning problem changes shape: batteries have limited range, chargers have limited throughput, and each vehicle's usable duty cycle depends on time-of-day charging economics. Optibus has been one of the primary software beneficiaries of that transition, building modeling capacity for electric-fleet operations that legacy scheduling software cannot match.
The customer base
Optibus operates in more than 5,000 cities across the U.S., Europe, Latin America, and Asia-Pacific — a coverage footprint unusual for a company of its funding stage. Publicly disclosed operator relationships have included major U.S. transit agencies, European private operators such as Transdev and Keolis, and multiple Latin American municipal networks.
The commercial model runs through both direct sales to transit agencies and channel partnerships with the private operators that hold contracts to run public networks on behalf of municipal authorities.
Category position
Optibus competes primarily with Trapeze (owned by Constellation Software's Modaxo unit), Hastus (owned by GIRO), and legacy incumbents in transit-scheduling software — companies whose products were architected before the modern optimization or cloud eras. The competitive frame is one Optibus has been careful to state cleanly: this is a category-modernization play, not a category-creation play. Transit agencies have been buying scheduling software for forty years. The question is which vendor's software they buy next.
Adjacent competitors include the on-demand transit software category (Via, Optibus's fellow Israeli-founded transit-tech company on olam's coverage), micromobility platforms, and mobility-as-a-service integrators. Those adjacencies do not overlap Optibus's core buyer.
Funding trajectory
Optibus's funding history sits inside a small handful of Israeli unicorns that reached the milestone in the 2020–2022 window. The Series C in May 2021 was followed by a Series D of approximately $100 million in November 2022, led by Insight Partners with Bessemer, Blackstone Innovation Investments, Tencent, and Verizon Ventures participating. The Series D was reported at a valuation of approximately $2 billion, consolidating the company's position as the largest AI-native transit software business globally.
Position in the Israeli cohort
Optibus sits inside the small but growing Israeli mobility-and-transit cohort that also includes Via in on-demand shared transit, Otonomo (now part of Urgentiy) in connected-vehicle data, and Autofleet in fleet-orchestration. The shared characteristic is the application of Israeli algorithmic-optimization expertise to a mobility-industry software layer that had, until recently, been underexposed to modern engineering practice.
The pairing with Via is particularly natural: Via operates the transit service (the demand-side software), Optibus plans it (the supply-side software). Both companies emerged from Israel within a decade of each other and both grew commercially most quickly through partnerships with public transit agencies globally.
Current standing
Optibus is the largest AI-native transit-scheduling software company globally, with the deepest deployment footprint across public and private transit operators in most major markets. The electrification transition — every large transit agency in the developed world is either mid-transition or planning one — has produced a favorable structural tailwind for modern planning software that legacy vendors architected in earlier eras cannot easily match. Optibus's engineering base has remained in Tel Aviv through the growth cycle, and the company continues to expand geographic coverage rather than product category. The strategic frame is straightforward and has not shifted: public transit is a large, structurally under-modernized software market, and Optibus intends to be the vendor that captures the modernization cycle.
