Episode description:

In this episode we speak to Christian Greis, a Dermatologist at University Hospital Zürich and the Founder behind derma2go, a Swiss digital dermatology platform built to help patients get expert skin assessments faster through online photo-based consultations. Christian shares how his path from clinical medicine into entrepreneurship was shaped by real-world demand, and how he built derma2Go while staying close to the medical frontline.

Christian speaks about how derma2go creates a win-win through hybrid care - solving 75–80% of cases online and routing the remainder in-house - and what it takes to shift patient behavior from long waiting lists to digital-first care. Christian also breaks down the realities of operating a two-sided platform in healthcare and why the company pivoted toward a B2B2C model by partnering with hospitals and clinics.

Christian also goes deeper into his founder journey: the trade-offs of solo founding, why sidepreneurship can be a strategic advantage in regulated markets, and what Christian learned from Innosuisse training and coaching. Finally, he shares a pragmatic view on fundraising and why it’s important to stay lean and raise only what you need.
