circleheads

Born. Based. Brooklyn.

Two people who grew up around the same traffic circle, now building applied AI in production, keeping a short consulting bench, and shipping the odd game.

The circle

Bartel-Pritchard Square, where Prospect Park West meets Prospect Park Southwest. Chaotic, communal, and central. Traffic lights and all.

The name

We grew up around the circle, bartel-pritchard sq, where Park Slope meets Windsor Terrace. Our friend group got called the circleheads. It stuck.

How we build

We watch the work before we build, then ship a production system: the data it needs, the skills it uses, and approval gates that keep humans in control.

Who are the circleheads?

Ieuan and Blaise, friends since we were ten.

Blaise

A developer and creator working on open infrastructure for human-agent research coproduction: full-stack systems, agent tooling, and the verification and evaluation layers that keep outputs honest. Grounded in econometrics and causal inference.

Ieuan

A product designer and technical anthropologist working on the human side of applied AI: discovery, approval flows, and the interfaces that make agents legible and worth trusting. Plus the agent training, front-end, and procedural 3D work behind them.
