Studio Northstar builds and runs its own products with ARCS, our agentic platform, the same one we bring to client work.

Our own products

Plens
Live · Open sign-up
Route-aware rain advice that compares nearby departure times and tells cyclists, runners and walkers when a small shift makes the trip drier.
How we built Plens
Attentico
Live · Early users
An AI gifting autopilot that remembers every date, picks a personal gift, and sends a handwritten card, always early.
How we built Attentico
FamAway
Live · In use on real trips
One trip, on everyone's phone, working offline: planning, bookings, real travel times per leg and a map that keeps working without signal.
How we built FamAway

ARCS and Northstar One are not products. They are the system the products are built and run with, and what we bring to client work.

ARCS
In use on every product
Seventeen specialist councils that review, build and re-check work, the system every other Studio Northstar product is built with.
How ARCS works
Northstar One
Serving internal workloads
Our own machines running our own models, so work with sensitive data or a 24/7 schedule never has to leave the building.
