Arjan van Eersel

Founder and Director

Synthonyx Group Ltd

Who I Am

I’m a software developer, systems thinker, and unapologetically anti-bureaucratic founder. Before Synthonyx, I spent years in corporate services, advising international companies on structure, compliance, and cross-border strategy. But I didn’t build Synthonyx to make things more complicated; I built it to make the right things simpler.

I believe the world doesn’t need more platforms, products, or pitch decks. It needs principled builders willing to solve the unsexy problems: compliance, business processes, and operational infrastructure. And to solve them well.

Why I created Synthonyx

Synthonyx Group Ltd is my holding company for building sovereign European technology. Not a fund. Not a consultancy. A holding company that builds products, participates in promising ventures, and co-founds companies where the mission matters.

I don’t “advise.” I participate.
I don’t chase funding rounds. I build systems that justify them.
I don’t believe in reinventing bureaucracy. I believe in engineering clarity.

Through Synthonyx, I bring execution, architecture, and skin in the game, for the right projects, with the right people.

What I bring to the table

• Full-stack development across Rust, Go, Dart/Flutter, and TypeScript/React Native
• Multi-sector experience: compliance tech, sovereign infrastructure, enterprise software, education, content, and AI
• Real-world delivery: from MVPs under pressure to investor-backed launches
• Deep involvement: I work alongside founders, not above or behind them

If you want a co-founder who understands infrastructure, not just interfaces, that’s where I come in.

What I’m looking for

I’m open to new ventures if:

• You’re serious about building something that matters
• You need a co-founder who’s as comfortable in the terminal as in a board meeting
• You value clarity, commitment, and execution over noise, pitch decks, or politics

If that’s you: Get in touch.

Technology encodes values. I build systems that encode sovereignty, precision, and digital independence.
