Tushen Zhihe, an AI protein-design company, raises several hundred million yuan over two rounds, its Pre-A led by Shanghai Kechuang Group
The money goes first to the company's own drug candidates, and its own candidates are where an AI protein-design company has to show that its designs work as medicines. MegaRobo, a maker of lab automation, invested to link its automated labs to the company's design-and-test loop, and the Pre-A came from Shanghai's state-backed venture group, which calls AI for science in biomedicine one of its main investment directions.
What happened: Tushen Zhihe, founded in Wuxi in late 2023 by Yuguang Wang, an associate professor at Shanghai Jiao Tong University's Institute of Natural Sciences, closed two rounds totalling several hundred million yuan. Shanghai Kechuang Group led the Pre-A, joined by Zhongsheng Yinling, Zhoushan Tuyi and others; Jinding Capital, MegaRobo, Zero2IPO Holdings and others invested in the Pre-A+. The money is to take several of its own programmes toward IND filings, upgrade its ToursynClaw design platform and hire. Its previous round, in September 2025, was an angel+ of around ten million yuan.
Why it matters: The money goes first to the company's own drug candidates, and its own candidates are where an AI protein-design company has to show that its designs work as medicines. MegaRobo, a maker of lab automation, invested to link its automated labs to the company's design-and-test loop, and the Pre-A came from Shanghai's state-backed venture group, which calls AI for science in biomedicine one of its main investment directions.
Evidence and limits: The results are the company's own, in the round's announcement: more than 100 antibody-engineering projects checked in real experiments, one design-and-test round in 14 days, more than 5,000 experimental data points. No paper or partner-reported result was found, its programmes and targets are not named, and neither the split between the two rounds nor a valuation is disclosed.
