Meet the Founder

Succeeded. Failed. Learned it All.

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. I'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.

01 · Validating

You have an idea. You want to know if it's real.

For founders still testing the market, shaping the problem, or looking for the right people to build it with.

  • Idea Analysis

  • Customer Discovery
    Interviews, personas, pain points
  • Co-founder Search

02 · Building

You're heads-down getting the first version out.

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

  • MVP Development
    Roadmap, prioritisation, launch
  • Distribution & Growth
    Go-to-market, channels, growth
  • AI & Automation

  • Fundraising Strategy
    Outreach, due diligence, valuation
04 · Scaling

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

For founders with traction who are hitting the limits of what worked before: team, product, leadership, operations.

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