Pony.ai

Pony.ai is an autonomous driving company founded by CEO James Peng and CTO Tiancheng Lou that has pursued L4 Robotaxi technology since roughly 2016 . Unlike competitors such as Horizon Robotics that focus on L2辅助驾驶 for multiple automakers, Pony.ai has concentrated on building full self-driving taxi fleets where the autonomous system retains primary control .

The company's funding history traces back to at least 2017, when 5Y Capital partner Zhang Fei first met Peng at Pony.ai's Beijing office, with 5Y going on to co-lead the Series B in early 2018 and participate through subsequent C and D rounds . Toyota became a pivotal investor in 2020, contributing $400 million at a $3 billion valuation—double the prior round—and the partnership has since deepened into joint vehicle development . Other backers include NIO Capital, Eight Roads, and Ontario Teachers' Pension Plan .

Pony.ai's collaboration with Toyota began with pilot programs using Lexus RX vehicles in 2019 and progressed to co-developed production models, including sixth-generation systems unveiled at the 2022 China International Import Expo and seventh-generation Robotaxi vehicles announced in April 2025 . The company also secured a $100 million investment from Saudi Arabia's NEOM and NIF fund in October 2023, with both Peng and Lou attending the signing . Pony.ai went public on the Hong Kong Stock Exchange in November 2025, with Peng describing the moment as standing "at the eve of large-scale commercialization" after nearly nine years .
