One model, many hands
A single cross-embodiment policy runs across grippers and humanoid hands.
The manipulation layer for robots
Human-level grasping for any robot hand
GripSim gives any gripper or hand reliable grasping and in-hand reorientation. One cross-embodiment model, trained on a data flywheel, that gets smarter with every grasp.

Why GripSim
Everything a robot needs to grasp
Hardware stopped being the bottleneck. Manipulation is. We ship the layer that fixes it.
Touch + vision
Tactyl predicts slip and force before the robot commits to a grasp.
Closed-loop control
Reactive, in-hand control instead of brittle open-loop scripts.
Source-grade integration
Drop-in policy, runtime, and skill API for your robot stack.
100+ object types
Trained on deformable, occluded, and novel objects in simulation.
Experts standing by
Robotics engineers help you pilot, fine-tune, and ship.
What's new
A data flywheel competitors can't clone
Every deployed hand logs real contact data that sharpens the shared policy. Each new customer starts ahead of the last.
- Cross-embodiment dataset that compounds
- Morphology-transfer to new grippers fast
- Sim-to-real bootstrapped by Simdex
How it works
From hardware to dexterity in four steps
1
Connect your hand
Register your gripper or hand and its sensors with Dextra.
2
Fine-tune
Adapt the pretrained policy to your cell with a small dataset.
3
Deploy to the edge
Reflex runs the policy on Jetson at control-loop latency.
4
Sequence tasks
Sequa chains grasps into full jobs and recovers on failure.

From bin-picking to humanoid hands
Start where the payoff is daily — warehouse picking and machine tending — then expand to humanoid, service, and medical manipulation.

The GripSim stack
Five products, one manipulation brain
Each product is a component of the same idea — the manipulation layer for robots.
Dextra
Cross-embodiment VLA manipulation foundation model + fine-tuning toolkit.
Tactyl
Tactile-and-vision contact world model that predicts grasp outcomes.
Reflex
On-robot edge runtime for low-latency closed-loop manipulation.
Simdex
Domain-randomized manipulation simulation + data-generation engine.
Sequa
Agentic skill API that sequences and recovers grasps into tasks.
200k+
Grasp episodes simulated (target)
50k+
Object variations in training

From the field
What robotics teams say
“Manipulation was our blocker for two years. GripSim gave us a policy that just works across our grippers.”
“The data flywheel is the real moat. Every cell we add makes the next one easier.”
“Reflex on Jetson hit our cycle-time budget on the first try.”
Questions
Frequently asked
Do you build robots?
No. We build the manipulation layer — model, runtime, and skill API — for the robots you already build or operate.
Which hands are supported?
Dextra is cross-embodiment and supports many gripper and hand morphologies; new hands are added via morphology-transfer adapters.
Does it run on the robot?
Yes. Reflex runs the policy on NVIDIA Jetson at control-loop latency, with fleet OTA updates.
How do you train without lots of real data?
Simdex generates domain-randomized contact-rich data in NVIDIA Isaac Sim, then the flywheel adds real data per deployment.
Why GripSim
Built for production robotics
The manipulation layer teams ship with, not a research demo.
Cross-embodiment by design
One policy runs across many grippers and hands — no per-robot rewrite.
Closed-loop with touch
Tactyl predicts slip and force so grasps react before they fail.
Runs on the robot
Reflex executes on Jetson at control-loop latency, with safety limits.
A moat that compounds
Every deployment feeds the shared model through the data flywheel.
