Products
Four products, one loop, one network.
Nexa is the body. Nexus, NexCap, and NexSim are the model, data, and simulation systems that make Nexa possible. NexNet connects them into a human-governed network for shared tasks and learning, while every Nexa remains safe and capable locally.
The body
Nexa
A synthetic body built to human specification
Skeleton, actuation, face, skin and whole-body sensing, all held to human-level structure — a body that can be scored layer by layer. This is what we ultimately deliver.
ReadThe mind
Nexus
A foundation model whose subject is the person
Mainstream world models predict the physical environment. Nexus predicts the human — their state, their intent, their limits. It is the precondition for an android that can be around people.
ReadThe simulation
NexSim
Where Nexa learns before it acts
Physiologically accurate simulation of a real biofidelic body, fast enough to train at scale. A rigid-body simulator trains real intuitions about force and balance — just not ours. This one trains against a body that pulls rather than pushes, so the training transfers to one.
ReadThe data
NexCap
Human behaviour, turned into trainable data
Large-scale capture of real human touch, motion, physiology and interaction — feeding Nexus training and Nexa evaluation from one dataset. The more data, and the more real it is, the closer the body gets.

Why these are one company
Capture feeds the model, the model drives the body, the body is measured, and the measurement decides what to capture next. Break the loop anywhere and the other pieces stop improving.
- 01CaptureNexCapReal human behaviour becomes synchronised, structured, trainable data.
- 02SimulateNexSimCaptured human data trains a physiologically accurate body in simulation before it acts in the world.
- 03ModelNexusThat data trains a foundation model whose subject is the person — state, intent, boundaries.
- 04EmbodyNexaThe model drives a body built to human-level structure, motion and sensing.
- 05MeasureBiofidelity BenchmarkThe result is scored layer by layer, and the gaps point back at the next capture round.
Make the built indistinguishable from the born.
The net
NexNet: one network, under human authority.
NexNet connects many Nexa bodies without centralising safety. People define goals, permissions and boundaries; the network coordinates tasks and shared learning; each Nexa keeps the perception, planning and safety systems it needs to act safely on its own.
- 01
Nexa
Local autonomy and safety
Each body maintains local perception, motion planning, collision avoidance, safe stop and task execution. Critical control never depends on a stable cloud connection.
- 02
Nexa Edge
Coordination at the site
An edge node coordinates the Nexa bodies sharing a home, hospital, factory or worksite: local maps, shared space, low-latency collaboration and continued operation during disconnection.
- 03
Nexa Control
Tasks, permissions and global state
The control layer turns human goals into bounded tasks, matches them to available Nexa bodies and maintains permissions, oversight, scheduling and an auditable system view.
- 04
Nexa Knowledge
Validated memory and learning
Experience, skills, models and data become shared knowledge only after training, simulation, safety validation and staged release - so one failure cannot become a network-wide behaviour.
- 01Human goals, authority and vetoes remain explicit.
- 02Local safety takes priority over every remote instruction.
- 03Access is scoped by person, organisation, body, place and task.
- 04Knowledge is validated and released gradually, never broadcast blindly.
