About Glass Frog Ventures

Glass Frog Ventures is a group of four experienced entrepreneurs and business angels who joined forces to invest in early-stage growth companies. We know and trust each other very well, and we all have a wide range of experiences and learnings to share for your growth. We have led large corporates, started businesses, failed at some, built new products, invested in many and have an extensive network.

We have learned from experience that by combining funding with true engagement, we are able to ignite early-stage companies on their path to success.

We also aim to lead or contribute to follow-on investments in our successful portfolio companies.

Glass Frog Ventures participates in the Seed Business Angel scheme of the Dutch government.

What we are looking for

Early-stage innovative companies. Preferably headquartered in the Netherlands. Ticket size €50k – €500k.

Sure, we are looking for some existing revenue and an excellent, scalable business plan. But we are also looking for something special in you that resonates with us.

You can impress with

Team

You have an intuitive sense of problems as customers see them and focus strongly on solving these customer problems — this is your drive.

You have grit: you are the type of person who pushes projects forward without being told to do so — impatient, wanting to make things happen.

Sound self-reflection on strengths and weaknesses — great if we can add value to make the team even stronger.

Scalability

The business model is scalable.

You have a Grand Vision and a Big Hairy Audacious Goal (BHAG).

The founding team shows relentless ambition to achieve its BHAG.

Customer success

Your product or service addresses real customer demand and pain points. This has been proven through real customer interaction.

Financial & business plans

We prefer quality over quantity: realism is more important than enormous detail. Unit economics must be sound. The team's ability to execute is more important than a pumped-up business case.

How we work

  1. Share your deck

    Send your pitch deck via the form below or to info@glassfrogventures.com. A few pages covering the problem, your solution, the team and your traction are enough.

  2. First call

    If there is a potential fit, one of the partners reaches out for an online introduction — to get to know you, your ambitions and what drives you.

  3. Deep dive

    We meet in person and dig into the business together: market, product, plan and the numbers. You meet all four GFV partners.

  4. Term sheet

    If we are all enthusiastic, we put our proposal on paper: a clear term sheet setting out the investment and our role as equal business partners.

  5. Due diligence

    A focused check of the facts — legal, financial and the cap table — without unnecessary overhead for the team.

  6. Close

    We sign, the funding lands, and we get to work — side by side, from day one.

Know what you'll actually keep

When you raise, the terms — a liquidation preference, a convertible's cap and interest, an option pool — often shape your outcome more than the valuation does, and the effect only shows up at exit. Our free Founder Outcome Simulator lets you model your rounds, see what you would walk away with at any exit valuation, and lay two deals side by side to find the point where the better-looking one stops being better. No sign-up, and nothing is stored.

Team

Rolf Fouchier

Rolf Fouchier

I have many years of CEO-level experience focusing on growth and transitions. Years ago I turned my career towards becoming an entrepreneur, start-up builder and investor. No more suits and ties or fancy job titles — realizing true impact is what matters.

Together with a team, I love to bring positive change and drive results. Passion for renewable energy and innovation.

I like to engage in proposition building, sales and leadership development.

Since I was a small child I have always been intrigued by technology. I was constantly trying to find things out and building stuff.

I was privileged to continue to do so when I started my own company.

Now I have a passion for helping ambitious entrepreneurs achieve their goals.

Arnoud Kamerbeek

Arnoud Kamerbeek

I enjoy helping the companies we have invested in with advice and hands-on support that is rooted in practical experience. I am the CEO of AI scale-up Jungle, and there are many common challenges in the growth path of my own company and that of the companies we have invested in with GFV.

Before becoming an entrepreneur, I cut my teeth as an engineer, consultant, board member and finally the CEO of several large industrial companies. This has helped me build a strong network.

Curiosity, opportunism and improvisation have driven me throughout my personal and professional life and fostered a broad interest in science, finance & investment, economics, and entrepreneurship. I bring C-suite and leadership experience in various roles and in numerous sectors and companies.

As an informal investor I like to have skin in the game. I enjoy working side by side with talented entrepreneurs and helping to translate their innovative technologies into commercially viable businesses. Sustained funding, deal structuring, a good team and aligned interests are key success factors I can contribute to.

Glass Frog Trivia

A glass frog sitting on a leaf
  • The translucent skin of some species permits an observer to see the frog's beating heart.
  • The male frog guards the females' fertilized eggs placed on leaves until they hatch and the tadpoles fall into the water.
  • The glass frog can jump more than ten feet in one jump.
  • The glass frog lives high in the trees above mountainous streams during the dry season. When the rainy season comes, it climbs down to the stream level to mate.
  • Glass frogs live up to 14 years.
