360 Security Technology

Zhou Hongyi, as founder, chairman, and CEO, retains ultimate authority over the firm's investment activity. There is no separately branded family office or independent investment committee operating at arm's length from the listed parent. The corporate venture arm, 360 Capital, houses a professional investment team that sources and executes early-stage deals, but material strategic acquisitions — such as the Nezha Auto stake — are driven directly by Zhou.

It is a publicly listed operating corporation on the Shanghai Stock Exchange, not a family office. However, Zhou Hongyi's controlling stake and the firm's pattern of using balance-sheet capital for strategic, long-dated bets give it some of the behavioral characteristics of a principal investor. No separate family office vehicle for Zhou's liquid wealth is publicly known to exist.

In 2021, 360 Security Technology invested RMB 2.9 billion for an approximately 16.6% stake in Nezha Auto, the Chinese electric vehicle maker. The deal positioned 360 as the second-largest shareholder and gave it a platform to integrate its in-vehicle security and connected-car operating systems into a mass-market EV brand. The investment reflects Zhou Hongyi's thesis that car cybersecurity will become a non-negotiable regulatory requirement in China's smart EV market.

Zhou transferred approximately 6.25% of 360's shares worth roughly RMB 9 billion to his ex-wife Hu Huan in April 2023 (per Reuters, April 2023). A separate voting rights agreement ensured Zhou retained voting control over the transferred shares, leaving his governance authority unchanged. The settlement diluted his direct economic ownership but did not create a new investment decision-maker or separate pool of family-office capital.

The firm employs a dual approach. 360 Capital functions as a typical corporate venture capital unit, writing checks from tens of millions to several hundred million RMB into early-to-growth stage technology startups. For strategically critical bets — such as the Nezha Auto stake or the separation and subsequent cybersecurity-focused joint ventures — the parent company invests directly from its treasury, often taking board seats and pursuing integration rather than purely financial returns.
