K&S W Invest

Klaus and Susanne Würtenberger established K&S W Invest GmbH in 2011 to manage their investable wealth from Öhningen-Wangen in southern Germany. The capital base traces to Klaus Würtenberger's career spanning banking, medical technology leadership, and advisory services — a background that shapes the firm's preference for German-speaking life-science ventures. The office operates alongside LP Investment Partners Real Estate Projects, a mixed-use real estate vehicle based in Öhningen-Wangen. K&S W Invest pursues co-invested seed and early-stage stakes, entering deals alongside established lead investors rather than leading rounds. The firm's asset-class mix includes private equity, direct co-investments and SPVs, startups, real estate, and digital assets. Confirmed portfolio exposure includes neurotechnology company CorTec GmbH, where K&S W Invest appears as a co-investor alongside Santo Venture Capital (the Strüngmann family office), LBBW Venture Capital, and Mangold Invest. Geographic deployment centers on Germany, Austria, and Switzerland, with technology interests spanning biotech and Web3 applications within the life-science domain. The Würtenberger family office maintains a lean operating structure — Klaus Würtenberger serves as Managing Director, while Susanne Würtenberger acts as co-principal. Klaus Würtenberger also participates in the High-Tech Gründerfonds (HTGF) Coach Network as an accredited coach for high-tech startups, providing an additional sourcing channel into early-stage German innovation. The firm has no known additional offices beyond its Öhningen-Wangen headquarters. Altss research confirmed no recent operational events in the last 24 months beyond maintaining its existing portfolio profile. K&S W Invest sits at the intersection of a single-family office and an operating principal's network. Klaus Würtenberger's direct involvement in the HTGF coach network gives the firm a structured view into pre-vetted deal flow that most family offices of its size lack. The decision to co-invest exclusively alongside lead investors such as Santo Venture Capital and LBBW Venture Capital — rather than lead rounds — defines a capital-preservation posture that shifts due-diligence burden to institutional co-investors while maintaining access to venture-stage life-science returns.

Frequently asked questions

Who runs investment decisions at K&S W Invest?

Klaus Würtenberger serves as Managing Director of K&S W Invest GmbH, with Susanne Würtenberger as co-principal. Klaus Würtenberger's background in banking and medtech leadership informs the firm's investment direction. No additional investment committee members or external advisors are publicly disclosed.

How does K&S W Invest source proprietary deal flow?

The firm's sourcing model blends Klaus Würtenberger's personal network with structured access to early-stage opportunities. His role as an accredited coach in the High-Tech Gründerfonds (HTGF) Coach Network provides a direct channel into pre-vetted German high-tech startups. The HTGF connection exposes K&S W Invest to deal flow that typically reaches institutional co-investors, giving the family office an edge for a firm of its scale.

Does K&S W Invest participate in fund commitments or only direct deals?

K&S W Invest concentrates on direct co-investments and SPVs in seed and early-stage companies, rather than fund-of-funds commitments. The firm does not lead rounds; it enters alongside established institutional lead investors such as Santo Venture Capital and LBBW Venture Capital. This approach keeps exposure direct while shifting primary due-diligence responsibilities to the lead investor.

What investment stages does K&S W Invest typically target?

The firm targets seed and early-stage investments, with confirmed activity in mezzanine-stage instruments as well according to Altss research. Its co-investment in CorTec GmbH represents an early-stage life-science bet alongside institutional backers. K&S W Invest does not publicly disclose later-stage or growth-equity positions, consistent with its patient-capital mandate in German-speaking markets.

Which sectors does K&S W Invest explicitly avoid?

K&S W Invest has no publicly confirmed negative sector screen, but its confirmed activity clusters tightly around healthcare services, digital health, and industrial technology. The firm's portfolio and co-investor relationships suggest it avoids consumer internet, traditional energy, and heavy-industry sectors in favor of life-science and medtech applications within the DACH region.

Where does the underlying wealth come from?

The wealth managed by K&S W Invest originates from Klaus Würtenberger's career in banking, medical technology leadership, and advisory services. Susanne Würtenberger serves as co-principal. The family office has not publicly disclosed the specific businesses or liquidity events that generated the capital base, but the firm's investment focus mirrors Klaus Würtenberger's professional expertise.

Does K&S W Invest maintain philanthropic structures?

K&S W Invest has not disclosed a separate philanthropic foundation or donor-advised fund. Klaus Würtenberger's past civic involvement includes serving as 1st Chairman (Vorstand) of TuS Wangen from 2015 to 2017, which suggests a local community engagement pattern but does not indicate a structured philanthropic vehicle.
