Daxin Jiang
姜大昕
Daxin Jiang (姜大昕) is the founder and CEO of StepFun (阶跃星辰), the Chinese foundation-model company backed by Qiming Venture Partners . In Qiming's own coverage he appears frequently as the company's public voice — from a 2025 dialogue with Qiming managing partner Zhou Zhifeng on "exploring the uncharted territory of AI entrepreneurship" , to presenting to Xi Jinping during the April 2025 inspection of Shanghai's Model Speedway , to being named to NetEase's 2025 top-ten AI influencers list . As of January 2026 he still leads the company as CEO, working alongside Yin Qi (who took the chairman seat after StepFun's B+ round), chief scientist Zhang Xiangyu, and CTO Zhu Yibo on foundation-model R&D and an "AI + devices" commercial loop . Beyond his role at StepFun, elsewhere's corpus doesn't carry personal background — education, prior career, or age — so that's where the record stops.
