I’m Dennis, a Switzerland-based entrepreneur who’s lived the startup journey—from bootstrapping through sleepless nights to successfully creating a global business at scale. I co-founded and led as CEO a vertical SaaS company, built it from scratch, raised $40m venture capital and grew it from zero to a team of >300 people. No handouts, no shortcuts—just hardcore execution. Now, I’m here to help ambitious early-stage founders like you survive the grind and come out on top.
“Starting a company is like eating glass and staring into the abyss of death.” Bill Lee - Craft Ventures

I’m your sparring partner, someone who’s been in the trenches and can challenge your thinking, sharpen your strategy, and keep you moving forward. Whether you’re wrestling with product-market fit, plotting your next raise, or scaling your team, I’ve got your back with real-world know-how:
- Mentoring: Tailored guidance for ambitious founders
- Strategic Soundboard: Pressure-test your ideas with someone who’s done it
- Execution Edge: Practical moves to crush it
What I Bring to the Table

- Functional Expertise: Product Management, Finance, Go-to-Market
