World representation
How agents can work with environments that change, persist, and respond over time.
PRIVATE TECHNICAL ACCESS
Intelligence that can act in the world.
Vivacity is building infrastructure for agents that need more than an answer. They need to understand changing conditions, take action, and stay grounded in what happens next.
∂W / ∂tHUMAN-DEFINED PHYSICSRUNTIME FOR NON-LIVING SYSTEMS01 / OUR THESIS
Language helped machines understand what we say. The next step is helping them understand what their actions change.
02 / ACTIVE RESEARCH
Building for the space between intent and consequence.
Our work focuses on the systems an agent needs to reason about an environment, make a choice, and learn from the result. We publish when the work is ready to be useful.

Research should become infrastructure. Infrastructure should disappear into the work.
03 / CONCEPTUAL INSTRUMENT
See the transition, not just the answer.
An agent proposes an action. Vivacity keeps the state, isolates possible outcomes, and preserves the evidence behind the path that follows. This instrument is conceptual, but the system boundary is the point.

04 / EXECUTABLE WORLDS
Between a world model and the world it is asked to predict.
Vivacity is designed around a hard boundary: state records what is true, action proposes a transition, and execution determines what can become true next.

05 / SELECT PARTNERS
Working closely with a small number of ambitious technical teams.
We partner with selected startups where the hard part is not generating an answer. It is building an agent that can operate inside a real, changing system.
Engagements are technical, focused, and shaped around the problem. If that sounds like your work, we should talk.
