Company
The supply layer for physical-world AI.
Robots and embodied agents learn from real human task data, and that dependence is structural, not temporary. Motionstack operates the on-demand workforce that produces it: we begin with embodied AI and extend to any human task on the same infrastructure.
Our mission
AI learned everything the internet could teach it. The physical world was never online.
Physical competence cannot be acquired from text. A model has to observe real people performing real tasks, in real environments, with the physical motion attached. That data does not exist on the web; it has to be produced deliberately.
Motionstack produces it. We field contributors worldwide and capture the precise person and task a model needs, cleared for commercial training. Supply is the binding constraint on embodied AI today; removing it is the point.
At our core
A focused team building the data layer for physical-world AI, connected by curiosity, rigour, and a conviction that real intelligence is grounded in the real world.
Grounded in the real world
Embodied intelligence is learned from the physical world, not from the web. We build by capturing real people doing real tasks, because that is the data that transfers to a robot in a real home.
Consent is the foundation
Consent, ownership, and provenance are where we start, not paperwork added at the end. The only data worth producing is data that is clean to train on and clear to license.
We field, we do not wait
We do not post a request and hope it is filled. We go and produce exactly what is needed: the right people, doing the right tasks, in the right places, anywhere in the world.
Why teams choose us
Built around what your model needs.
Four reasons teams come to us instead of collecting the data themselves or settling for what already exists.
Data that generalises
01We field the same task across places, people, and conditions, so your policy learns the task rather than one room. Diversity is what holds up outside the lab.
Exactly your spec
02Name the task, the person, and the place. We source and dispatch the precise people you need, rather than waiting for the right contributor to appear. You get the dataset you specified, not the nearest match.
Delivered in about four weeks
03We run sourcing, capture, QA, and rights end to end. You get a production-grade dataset at volume, without standing up a collection operation of your own.
Clears your procurement
04Every clip is consented, owned, and auditable, with provenance and chain-of-title in the package. It passes legal review and drops straight into a commercial training pipeline.
How we operate
Procurement-grade from the first clip.
A senior team across sourcing operations, machine learning, and go-to-market, building the supply layer for physical-world AI. We treat rights and data handling as procurement requirements, not afterthoughts, so the data clears your pipeline on day one.
See trust & rightsConsent first
Every contributor signs a release. Everyone identifiable consents, or the clip does not ship.
Owned, not scraped
We own what we license. Broad, perpetual, sublicensable rights that clear downstream training.
Auditable provenance
Consent records and chain-of-title travel with every dataset. A package, not a black box.
