The 10x Group

The four co-founders — Felix Haas, Robert Wuttke, Andreas Etten, and Jan Becker — collectively manage investment decisions. Each brings operational experience from their prior companies, including Amiando and IDnow. The group does not publicly designate a single CIO or managing partner with ultimate decision authority.

FLEX Capital is a private equity fund founded by the same four partners. While The 10x Group focuses on early-stage to growth venture investments, FLEX Capital acquires profitable German software companies. The two entities share founders and likely some deal-flow sourcing channels, but operate as separate legal structures with distinct investment strategies.

The group is headquartered in Santa Rosa, California, but its disclosed portfolio companies — including MYNE Homes and Upvest — are based in Germany. Investment activity appears concentrated in German-speaking Europe, reflecting the founders' European network and prior company-building experience in Berlin and Munich.

The firm targets seed through growth-stage companies, based on its stated strategy. Specific check sizes are not publicly disclosed. The presence of a parallel PE vehicle, FLEX Capital, suggests the group can participate across a wide spectrum of company maturity without stage constraints.

The group deploys capital from the founders' own liquidity, supplemented by Grey Corp — a co-investment vehicle used by Wuttke, Etten, and Becker. It does not appear to operate as an open fund accepting third-party limited partners in the traditional sense, though the FLEX Capital entity may have a different structure.
