## People and structure
The firm's general-partner chain runs through three entities: Keytone Partners, L.P. is the general partner of Keytone Ventures; Keytone Ltd is the general partner of Keytone Partners; and Zhixiong Joe Zhou is the sole member and director of Keytone Ltd.[3](https://www.sec.gov/Archives/edgar/data/1447985/000114420418007482/tv485511_sc13g.htm) Zhou signed the firm's 2018 Schedule 13G as attorney-in-fact for the reporting entities, and aggregator records list him as an executive officer across filings spanning 2011 to 2026.[3](https://www.sec.gov/Archives/edgar/data/1447985/000114420418007482/tv485511_sc13g.htm) • [4](https://aum13f.com/firm/keytone-ventures-hong-kong-advisers-limited)
According to the firm's own website, the founding team includes the former Founding Managing Partner at KPCB China and a former partner at IDG-Accel, positioning Keytone among the early generation of venture investors in China.[1](http://www.keytonevc.com/) This is a self-description; independent confirmation of the individual partners' names and histories does not appear in the sources consulted here.
## Funds raised
**Fund I (2009).** A Form D amendment for KEYTONE VENTURES LP filed on August 6, 2009 recorded $198,500,000 sold, under the Investment Company Act Section 3(c)(7) exclusion, with a $500,000 minimum investment and a duration of more than one year;[6](https://www.sec.gov/files/formd.pdf) these details are reproduced by a Form D aggregator rather than drawn from the SEC filing itself.[4](https://aum13f.com/firm/keytone-ventures-hong-kong-advisers-limited) Venture Capital Journal reported on July 12, 2009 that Keytone had raised $200 million for its first fund, consistent with the filing.[5](https://www.venturecapitaljournal.com/keytone-ventures-raises-200-million-for-first-fund/) Private Equity International lists Keytone Ventures I with a close date of July 2009.[2](https://www.privateequityinternational.com/institution-profiles/keytone-ventures.html)
**Fund II (2010).** A Form D for Keytone Ventures II, L.P. filed on August 5, 2010 declared a $300,000,000 offering with $300,000,000 shown as remaining, that is, nothing recorded as sold at the time of filing, along with the same $500,000 minimum and 3(c)(7) exemption and a finder's fee of $1,500,000; these details are likewise aggregator-reproduced.[4](https://aum13f.com/firm/keytone-ventures-hong-kong-advisers-limited) The same aggregator separately lists Fund II at $235.1 million in assets under management as of March 31, 2012, which implies later closings beyond what the initial filing shows.[4](https://aum13f.com/firm/keytone-ventures-hong-kong-advisers-limited)
**Later filings (2021–2024).** Forms D attributed to the manager show three additional vehicles: Fund CI, filed January 6, 2021 (about $40.8 million); Fund KIII, filed January 10, 2023 (about $45.2 million); and Fund CII, filed January 3, 2024 (about $31.1 million).[4](https://aum13f.com/firm/keytone-ventures-hong-kong-advisers-limited) Whether these filings represent active fundraising by the same organization or administrative activity is not established by independent reporting.[4](https://aum13f.com/firm/keytone-ventures-hong-kong-advisers-limited)
