Meet the Founder

Built It. Lost It. Learned Everything.

14 years, 4 startups, and every lesson that comes with them.

I've been doing this for 14 years now. Four companies of my own. Some worked out, some really didn't. But every founder I talk to is dealing with something I've already been through. That's not a pitch. That's just what happens when you've been in the trenches long enough.

4x Founder

Two B2B SaaS companies, a marketplace, and an agency. Bootstrapped and funded. Iโ€™ve seen both sides.

650+ Founders Helped

From founders with an idea to post-raise teams trying to scale, and everything in between.

Mentor & Workshop Leader

I mentor founders through programs around the world and run workshops and presentations for them.

"If you are a founder building something real and need sharp, straight-forward, transparent and strategic feedback, I definitely recommend speaking with him. He helped me rethink where I should focus, what really matters in my strategy, and how to properly validate my problem and solution before trying to scale. His advice was clear, honest and practical."

What I Help With

I Work Where You Are

Wherever you are in the journey, there's probably a version of you in here.

For founders shipping an MVP, chasing their first real customers, and figuring out what actually moves the needle.

    Roadmap, prioritisation, launch
  • Distribution & Growth
    Go-to-market, channels, growth

04 ยท Scaling

It's growing. And it's also starting to break.

  • PMF & Scaling
    Metrics, roadmap at scale
  • Team & Hiring
    Hiring, structure, culture

Real Help for Founders Still Pre-Raise

Pre-raise founders need expert input but can't justify a โ‚ฌ2,000/month advisor. I get it. Two ways to work with me that fit where you are: a free monthly mentoring call when you need a sounding board, or a focused 90-minute deep dive when you need to unstick a specific decision.

  • 90-minute deep diveโ‚ฌ750
For founders who've raised

A Partner for Post-Raise Founders

Post-raise is a different game. Every week there's a decision that could compound for years: what to hire for, what to say no to, how to manage investors, when to pivot. I work with funded teams on an ongoing basis, monthly or quarterly depending on the cadence you prefer.
