Momenta
Momenta is a Robotaxi / AV company founded in 2016 and based in Beijing, China.
Momenta was founded in 2016 by Cao Xudong, a former SenseTime R&D executive, to build autonomous-driving software through a "two-leg" strategy: scalable, mass-production assisted-driving software for production cars (its revenue engine) and a fully autonomous Level-4 robotaxi program. Its strategic investors span global automakers and tech giants including General Motors, Toyota, Mercedes-Benz, SAIC Motor, Bosch and Tencent; GM invested about $300 million in 2021 and the company completed Series C financing exceeding $1 billion that November. Momenta has partnered with Mercedes-Benz on a robotaxi fleet and in mid-2026 priced its Hong Kong IPO — roughly 19.9 million shares at HK$295.60, raising about $752 million at a valuation near $9 billion, with cornerstone investors including GIC, Fidelity, BlackRock and Mercedes-Benz — with trading set to begin around July 8, 2026. Its prospectus disclosed 2025 revenue of RMB 2.41 billion (up 82%) against a net loss of RMB 3.46 billion.
Momenta is the leading bet that mass-production driver-assistance revenue can fund the path to robotaxi, and a rare AV company backed simultaneously by GM, Toyota and Mercedes-Benz.
