The team

Who we are

We’re a small, senior team spanning research, development and leadership. Between us, we’ve traded across asset classes, built trading infrastructure from the ground up, and run systematic strategies at hedge funds and proprietary trading firms. We keep the team lean and the feedback loops short. Everyone here researches, builds and ships.

What we value

Principles

A few principles we hold to.

Controlled risk

Risk is sized, limited and hedged systematically — never an afterthought.

Evidence over narrative

Every strategy earns its place through out-of-sample evidence.

Built to run

Research and production are one pipeline, engineered to ship and scale.
