Hyleen Capital

Hyleen Capital was founded in 2015 by Zhang Lei, the founder and CIO of Hillhouse Capital Group. The two firms share a founder but operate as legally distinct entities with separate investment mandates. Hyleen focuses on earlier-stage, concentrated venture and growth bets in China, while Hillhouse spans buyout, public equity, and multi-strategy allocations globally. The exact governance and deal-approval firewalls between the firms have not been publicly disclosed.

Hyleen deploys across seed, start-up, growth, and PIPE transactions, effectively covering the full Chinese private-company lifecycle from formation to pre-IPO. This full-stack approach allows the firm to follow winners from early venture rounds through later-stage capital raises. PIPE capability also provides a pathway into public markets when portfolio companies list in Hong Kong or mainland exchanges.

The portfolio concentrates on enterprise software, artificial intelligence and machine learning, healthcare services, and mobility — hard-tech and productivity themes rather than consumer internet or platform plays. Known positions include autonomous driving chipmaker Horizon Robotics, AI firm Megvii, and edtech platform Yuanfudao, all reflecting a thesis that China's next growth phase will be driven by automation and enterprise digitization.

No. Hyleen has never publicly disclosed assets under management, fund sizes, or aggregate deployment figures. The firm does not file a US 13F, has no SEC-registered affiliate, and has never appeared in a limited partner disclosure tracked by major data providers. The opacity is deliberate and consistent with mainland China's regulatory environment for private funds.

There is no public evidence that Hyleen participates in co-investment syndicates with external general partners or accepts capital from outside limited partners. The firm's deal structures appear to rely on direct equity and convertible instruments funded by proprietary capital. Whether that capital originates solely from Zhang Lei, from Hillhouse-affiliated entities, or from a discreet LP base remains undisclosed.

Zhang Lei is the founder and the named principal associated with Hyleen Capital. No investment committee members, partners, or senior professionals beyond Zhang have been publicly identified in connection with the firm. Whether Hyleen maintains a dedicated investment team or relies on shared resources with Hillhouse has not been disclosed by either entity.

Hyleen has maintained minimal public profile since 2023. Portfolio company Horizon Robotics filed for a Hong Kong IPO in 2024, and Yuanfudao underwent significant restructuring following China's 2021 crackdown on for-profit tutoring — both events materially affecting Hyleen's holdings. The firm has issued no press releases, disclosed no new fund closes, and announced no new deals in the past 24 months.
