Hong Kong-based Monolith Management, a prominent AI-focused investment firm in China operating across venture capital (VC) and hedge fund strategies, has secured a commitment of 1.5 billion yuan ($223.5 million) from Zhihu Inc for its new RMB-denominated, early- to mid-stage artificial intelligence (AI) fund.
Co-founded in late 2021 by former Boyu Capital partner Tim Wang and Cao Xi (曹曦), who became the youngest partner at VC giant HSG (previously Sequoia China) at age 36 after just eight years with the firm, Monolith has assembled a portfolio of highly sought-after Chinese AI champions, including DeepSeek and Moonshot AI.
In a September 6 stock exchange filing, the popular Q&A-inspired online content platform Zhihu, often described as the Chinese equivalent of Quora, disclosed its cash commitment to the blind-pool RMB vehicle, named “Tianjin Lisi Xingshen Equity Investment Partnership (Limited Partnership) 天津砺思星深股权投资合伙企业（有限合伙）,” to become a limited partner (LP) in this fund incorporated in May this year.
Zhihu said that its 1.5-billion-yuan commitment will represent no more than 30% of total fund interests, according to the filing. This implies a fund target of at least 5 billion yuan ($745.1 million).
The AI-focused RMB vehicle will feature a seven-year fund life, extendable by Monolith for up to two consecutive periods of one year each—with its LPs paying “a mid-single-digit percentage” management fee on paid-up capital contribution. It will operate with a four-year investment window starting from the first closing date, the filing shows.
The fund’s focus on foundation models, AI infrastructure, robotics, and AI applications aligns with Zhihu’s ongoing efforts to integrate AI across its ecosystem. Key initiatives include expert data solutions, AI-enabled content and IP operations, and Zhihu Zhida, an AI-powered search and answer engine launched in mid-2024, according to the filing.
This LP commitment is expected to broaden Zhihu’s access to investment opportunities in high-quality AI and tech enterprises and deepen its understanding of the development of AI tech, products, and business models for potential synergies with existing AI-related offerings, said Zhihu.
The deal comes at a pivotal moment for Zhihu as the 15-year-old Chinese content platform grapples with persistent monetisation challenges, despite raising $523 million in its 2021 US listing and an additional $106.3 million through a dual-primary Hong Kong listing in 2022.
The company reported total revenues of 1.34 billion yuan ($199.7 million) in the first half of 2026, down 7.25% year-over-year (YoY). Adjusted net profit dropped to 6.9 million yuan (approximately $1 million), versus 98.3 million yuan ($14.6 million) in the same period last year.
