The 10x Group
Felix Haas and three co-founders run The 10x Group, a dual-vehicle investment operation spanning early-stage tech and PE buyouts across Europe.
The 10x Group
The 10x Group operates from Santa Rosa, California, but its investment gravity is distinctly European. The four founders — serial entrepreneurs Felix Haas, Robert Wuttke, Andreas Etten, and Jan Becker — created the firm after building and exiting companies including events platform Amiando (sold to Xing) and identity-verification provider IDnow. Their personal liquidity events supply the core capital, deployed alongside Grey Corp, the co-investment vehicle used by Wuttke, Etten, and Becker. The group targets companies from seed through late-stage venture, with a generalist technology mandate that has led them into fintech, proptech, and enterprise software. Confirmed portfolio holdings include Upvest, a Berlin-based investment infrastructure API provider, and MYNE Homes, a fractionalized property ownership platform operating across Germany. The founders also launched FLEX Capital, a private equity fund that acquires profitable German software companies — a separate strategy that sometimes shares sourcing channels with the earlier-stage 10x Group vehicle. The geographic focus remains concentrated in German-speaking Europe, with Berlin as the operational nexus. Felix Haas brings additional institutional connectivity through his seat on the 'Young Digital Economy' advisory board to the German Federal Ministry of Economics and Technology. The four founders split attention between The 10x Group's direct tech investments and FLEX Capital's buyout activity, creating an unusual funnel where early-stage relationships can mature into private-equity candidates. The group does not publicly disclose AUM or headcount. The firm's central structural distinction is its dual-vehicle, generalist architecture. Most family-backed investment operations choose venture or buyout. The 10x Group runs both, with the same four principals, using separate legal structures. That creates a spanning capability — the team can write a seed check from the group vehicle and later acquire a similar company at scale through FLEX Capital. The model is rare for a four-founder, non-institutional shop.

Frequently asked questions
Who runs investment decisions at 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.
How is The 10x Group related to FLEX Capital?
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.
Does The 10x Group invest in Europe or North America?
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.
What is The 10x Group's typical check size or stage?
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.
Does The 10x Group accept outside capital?
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.
