What we do

We build games people enjoy, and tools that help companies carry their projects through to the end.

Game development

We also run a travel planner on the web, where AI builds your itinerary.

How we work

We pair 30 years of planning and leading IT projects with AI coding agents, so a small team can build large products quickly. People make the design decisions; AI handles repetitive implementation and checking.
