Sandborn

Isabelle Siegrist, the founder, is the central investment decision-maker. Her background includes building companies at Startups.ch as CIO before launching Sandborn, and she personally takes board seats at portfolio companies. The firm does not disclose a formal investment committee beyond Siegrist.

Siegrist leverages a network built over a decade in the Swiss startup ecosystem, including her roles as an Innosuisse coach, university lecturer, and Forbes 30 Under 30 alumna. The firm also runs corporate innovation partnerships with institutions like Migros and Die Mobiliar that generate venture-building mandates.

Sandborn operates primarily as a company builder. It validates ideas, builds MVPs, and helps startups scale with operational support and direct investment. It also earns revenue through corporate advisory work, making it a hybrid between a venture studio and an innovation consultancy.

The firm's website describes making direct investments into portfolio companies, but does not disclose whether it manages a pooled third-party fund. It connects startups to its investor network, suggesting a co-investment or syndicate model rather than operating as a fund-of-funds.

Sandborn does not publish a negative sector list. Its disclosed portfolio and corporate projects cluster around digital business models in enterprise software, AI, proptech, agritech, mobility and media, indicating a focus on asset-light, scalable ventures rather than deep tech or capital-intensive infrastructure.

Sandborn's website lists both S2S Ventures and AI Launchpad as initiatives it contributes to, but does not clarify whether it manages them, co-owns them, or participates as a partner. The precise legal or operational connection is not publicly detailed.

There is no public disclosure of a philanthropic arm, foundation, or donor-advised fund. The firm's Academy and book publishing activities operate as commercial or educational extensions of the brand, not as charitable vehicles.
