Qingdao Taiyi Investment Development

Cong Wei holds 80% of the firm and serves as Founder and Executive Director, making him the central investment authority. Supervisor Wang Jiancheng owns the remaining 20% but has no publicly documented role in deal selection. The investment process appears to rely on Cong Wei's personal network, as evidenced by repeat co-investments with Yuan Hao and Yao Xiaochao alongside Frees Fund.

The firm sources deals through a tight syndicate network centered on Frees Fund, a Beijing-based venture capital firm, and recurring individual co-investors Yuan Hao and Yao Xiaochao. This pattern suggests a relationship-driven origination model rather than a broad public intake or proprietary scouting platform. The Qingdao location also points to potential local Shandong provincial network access.

Qingdao Taiyi invests at the earliest stages of company formation — seed and start-up rounds. Its one confirmed portfolio holding, F=ma, was backed at these early stages alongside Frees Fund. The firm does not publicly disclose participating in growth-stage or later-round investments.

Legally registered as an asset manager, Qingdao Taiyi functions in practice as a closely held investment vehicle with an 80% single-owner concentration under Cong Wei. Its lean structure and repeat-syndicate co-investment pattern blur the line between a formal venture firm and a single-investor platform, though it makes no claim to managing family wealth.

Available evidence points to enterprise software, AI/ML, and industrial technology. The firm's one known investment, F=ma, builds AI-based physics simulation tools for industrial and scientific use cases. Broader sector focus can be inferred from its co-investment relationship with Frees Fund, which is active across deep tech and enterprise domains.
