Northhaven Analytics | About

Built by a team
that gets it done.

We’re five people — quants, engineers, and developers — building synthetic data infrastructure and custom ML models for financial institutions, MedTech teams, and AI startups that operate in environments where precision isn’t optional. Founded in Warsaw in 2025. Remote-first from day one. No real data ever touches our systems.

Research-Driven Origins

„We proved that synthetic financial environments can accurately replicate real-world behaviour — without using a single piece of sensitive information.”

Northhaven Analytics was founded by Oleg Fyłypczuk and Gabriel Wiśniewski with a clear objective: to redefine how financial institutions access, test, and validate data in an era dominated by regulatory constraints and privacy rules.

What started as a research-driven experiment evolved into a specialised data company the moment we validated that hypothesis at scale. The result was a new class of infrastructure — one that lets quantitative teams move fast without compromising the integrity of production systems or the privacy of real clients.

Today, Northhaven operates at the intersection of synthetic data engineering, ML model development, and institutional risk simulation — building bespoke environments for private debt funds, enterprise banks, hedge funds, and fintech operators.
