Your mentor

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
Starting a business is tough. Scaling is tougher. I’ve done it - and I can help you do it too. I mentor ambitious early-stage founders and help them navigate through the chaos, drawing on hands-on experience across every corner of building a high growth tech business.

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
- Industries I Know Inside Out: SaaS (incl. SMB SaaS, Vertical SaaS, AI-enabled SaaS, Insurtech-enabled SaaS, Fintech-enabled SaaS), Online Travel / Travel Tech, B2C Marketplaces
- Functional Expertise: Product Management, Finance, Go-to-Market
- Leadership in Action: CEO, Strategy, OKRs, People Management, Board Dynamics
- Fundraising: Angel Rounds, Seed to Series A-C rounds

Who I work with
Ambitious early-stage startup founders who:
- Build tech or digital products.
- Have the grit to push through the glass-eating phase.
- Want a mentor to talk to who’s done it, not just read the book.

Frequently asked questions

What exactly is a session?

A session is a focused one-on-one call with your mentor. Use it to get feedback, work through a specific problem, review your work, or get unstuck. You reserve up to 30 min of their time.

How do I pick a time?

After checkout you pick a slot from Dennis's live availability, and it's confirmed on the spot.

How does the session take place?

Sessions happen over video call. Your mentor shares the meeting link ahead of time, so all you need is a quiet spot and a stable connection.

Can I reschedule?

Yes, up to 24 hours before the session. Message your mentor and find a new time that works for both of you.
