I build blockchain products to empower individuals

After building a MiCA-compliant euro stablecoin and exiting to Paxos in 2024, I’m now helping individuals lead financially healthier lives by supporting DeFi & stablecoin products in their journey toward ubiquitous adoption.

My journey in blockchain spans the entire ecosystem — from running the Nordic’s largest non-Bitcoin mining operation to leading product in DeFi, from scaling institutional credit platforms to navigating European stablecoin regulation. This breadth gives me a unique perspective on market micro- and macrostructures and how to build succesful blockchain products.

Now

• CTO at Based: using economic design to elicit higher quality information from subjective topis in an era where the voice of real people is drowning in noise.
• Chairman of Cairn’s Point: fullstack legal & tech consultancy for MiCA Title II token issuance and admission to trading.
• Advisory for select blockchain projects, with a focus on product development & strategy. Find my contact details at the end of the page.

Previously

Membrane Finance (Co-founder, Head of Growth & Product): Led product and growth for Europe’s leading stablecoin issuer. We achieved MiCA compliance first in the EU and a successful exit to Paxos in 2024.

Tracer DAO (Head of Product): Directed product strategy for a decentralised derivatives protocol on Arbitrum. Managed an international team through complex DeFi challenges before our merger with Mycelium in 2022.

Tesseract (Head of Growth): Scaled one of Europe’s largest institutional crypto credit platforms, culminating in Finland’s largest Series A in 2021.

Nordmine Technologies (Operations): Built and operated the largest non-Bitcoin mining facility in the Nordics — an education in infrastructure, economics, and operational excellence.

Beyond Blockchain

My academic background combines Financial Economics (Erasmus University Rotterdam) and Computer Science (University of Helsinki).

In addition to blockchain, I have worked with structured products at Garantum, developed virtual environments for the Finnish Defence Forces, and optimised systems for Google and Amazon.
