An operating platform since 2011 — own projects, investments, board mandates, and senior-advisor work.
Context
Founded in January 2011, at the moment of the move from corporate life to entrepreneur and in parallel with the first own start-up. Over the years, the original investment vehicle has evolved into a platform: ventures, angel investments, interim mandates, advisory engagements. Central back-office functions — finance, administration, operations — were consolidated at exigo and later offered to third parties as a service.
Contribution
Phase 1 (2011–2016) — Vehicle becomes platform
Three own ventures emerged in this phase, all structured through exigo: Bookletmobile (mobile micro-publishing, exited), paymy (mobile payment via SEPA direct debit), and GES Verlag (digital-only publishing). In parallel, two interim management mandates: Softgarden (interim CEO 2011–2012) and Vattenfall (Head of Network 2012–2016, originally planned as a six-month mandate, later extended to four years).
Phase 2 (2016–2025) — Builder and investor in parallel
The Sensorberg CEO phase (2016–2019) and the subsequent six executive-board years at Elia Group (2019–2025) ran alongside the exigo portfolio. The investments that today carry the investment strand of the endeavors page emerged in this period: Paretos (angel, since 2021, agentic AI for supply chain), w3.fund (founding LP, 2021), Sedisto (founding investor, 2022), and Cyberdesk (investor and advisor, 2023, identity-centric data security). Plus the first advisory mandates (Founders Foundation, ESMT Vali, Applysia, elevion green).
Phase 3 (from 2026) — Primary platform
With the conclusion of the executive-board role at Elia Group in December 2025, exigo becomes the primary platform: for topic work on agentic AI in enterprises and the security of critical infrastructure, for selective new investments, and for senior advisory mandates.
