Plocca was formed in 2020 by Thomas Dübendorfer, a former Google and Swisscom security architect turned angel investor, and David Senn, a software entrepreneur and early-stage backer. The Zurich-based multi-family office emerged from the pair's overlapping deal flow and a shared conviction that Swiss and European tech founders exiting their first companies needed a investment vehicle that spoke their language—one built by operators, not wealth managers. Unlike most Swiss multi-family offices that trace their roots to private banking, Plocca's founding team brought a decade of direct angel investing and startup operating experience. This shapes the firm's identity as a technology-first, rather than finance-first, allocator. The firm runs a concentrated equity strategy focused on pre-seed through Series A rounds across Europe, with deal sizes typically between CHF 250,000 and CHF 2 million. Its allocation mix spans enterprise SaaS, fintech infrastructure, and applied AI. Confirmed portfolio companies include Ledgy, the Zurich-based equity management platform (per the firm's official communications, 2021) and Yokoy, the AI-driven spend management company (per TechCrunch, 2022). Plocca also participates selectively in follow-on rounds and has co-invested alongside funds such as Speedinvest and Sequoia through SPV structures. The geographic emphasis remains Switzerland, Germany, and the Nordics, reflecting the firm's view that these markets remain under-allocated by pan-European venture funds chasing larger deal sizes in London and Paris. Plocca operates as a lean partnership with under 15 professionals, drawing its scale from the aggregated commitments of its member families rather than a single balance sheet. The firm does not disclose aggregate assets, and deployment is measured in deal volume rather than an AUM figure. In practice, the partnership commits approximately CHF 15–25 million annually into 15–20 new positions. August 2024: Co-founder David Senn joined the board of a Zurich-based AI governance startup backed by the firm (per the firm's official communications, August 2024). The office maintains a single location in Zurich and has no disclosed philanthropic vehicle, though individual principals have established donor-advised funds for Swiss educational and environmental causes. The structural differentiator is Plocca's club-deal architecture. The firm is not a pooled fund; each member family participates deal-by-deal through a dedicated investment committee that includes Dübendorfer and Senn alongside rotating family representatives. This gives the partnership the speed of an angel syndicate with the staying power of permanent capital. The governance model, which vests investment authority in the two co-founders as managing partners with a formal advisory council drawn from the member families, solves a common succession problem in operator-led family offices: it institutionalizes decision-making without requiring families to cede control to a third-party manager.

Frequently asked questions
Who runs investment decisions at Plocca?
Investment decisions are led by co-founders Thomas Dübendorfer and David Senn as managing partners. Dübendorfer brings a technical and security background from Google and Swisscom, while Senn contributes operating experience as a software founder. They work with a formal advisory council drawn from member families, but authority to commit capital rests with the two partners.
How does Plocca source proprietary deal flow?
Plocca sources primarily through the co-founders' personal networks built over a decade of angel investing across Swiss and German tech ecosystems. Dübendorfer's role as president of the Swiss ICT Investor Club and his visibility in cybersecurity circles provide early looks at deep-tech and infrastructure deals. The member families themselves, many of whom remain active operators, also surface opportunities from their own portfolio companies and peer networks.
Is Plocca structured as a single family office or a venture firm?
Plocca is a multi-family office that operates with the discipline of a venture syndicate. It is not a regulated fund manager and does not raise outside capital. Each member family commits capital on a deal-by-deal basis through special purpose vehicles, giving the partnership the flexibility of an angel network alongside the permanence and alignment of a family office.
Does Plocca participate in fund commitments or only direct deals?
Plocca deploys almost exclusively through direct equity investments in early-stage companies. The firm has occasionally participated in follow-on rounds alongside institutional venture funds through SPV structures, but it does not make primary commitments to third-party venture capital funds as a limited partner.
What investment stages does Plocca typically target?
Plocca targets pre-seed through Series A rounds, with initial check sizes typically between CHF 250,000 and CHF 2 million. The firm will selectively follow on in subsequent rounds and has demonstrated the capacity to lead or co-lead smaller pre-seed rounds where the co-founders' operating expertise is directly relevant to the founding team.
Where does the underlying wealth come from?
The member families' wealth originated primarily from exits in enterprise software, fintech, and cybersecurity—sectors the co-founders themselves operated in before forming Plocca. The firm has not publicly identified its member families, consistent with Swiss privacy norms, but several are known to be founders of companies with exits to US and European strategic acquirers.
Does Plocca maintain philanthropic structures, and how are they separated?
Plocca does not operate a centralized philanthropic vehicle. Individual principals have established donor-advised funds focused on Swiss educational and environmental causes, but these are maintained separately from the investment partnership and are not commingled with the firm's investment operations.
