About
I'm a founder and technologist who builds software for complex, regulated environments.
I co-founded Realm (Y Combinator S11), a mobile database platform that reached billions of installations before our acquisition by MongoDB. We raised over $40M and built a global developer community.
I founded Cohera, an enterprise compliance platform for pharmaceutical, medical device, and life sciences organizations. Our flagship product BioWise helps companies manage quality documentation, supplier certificates, and regulatory compliance.
What I Write About
- Regulated Industries — Building software that meets 21 CFR Part 11, EU GMP Annex 11, and other compliance requirements
- Enterprise Architecture — Integration patterns, legacy system modernization, data modeling
- Database Systems — From mobile databases to distributed systems, offline-first architecture
- Founder Journey — Lessons from starting, funding, and scaling technology companies
Background
My career has focused on building technology for hard problems. At Realm, we tackled mobile data synchronization when the industry said it couldn't be done. At Cohera, we're connecting legacy enterprise systems that were never designed to work together.
I've navigated companies from founding through Y Combinator, Series A fundraising, international expansion, and acquisition. I've built teams across Copenhagen, San Francisco, and beyond.
Key technical areas: compliance technology architecture, database internals, distributed systems, AI in regulated environments, enterprise integration (Veeva, SAP, TrackWise).
Speaking
I speak at conferences and company events about building for regulated industries, database architecture, and lessons from founding technology companies. Topics include AI in enterprise compliance, connecting legacy systems, and navigating regulated markets.

Advisory
I occasionally advise companies working on compliance technology, enterprise software for regulated industries, and technical architecture challenges. I also support investors with technical due diligence in these domains.
If you're building something in this space, I'd enjoy hearing about it.
