The problem

Intelligence is racing ahead. The physical world isn’t.

AI got 300× cheaper. Building didn’t.

Physical AI is outpaced by digital AI.

Not good enough

Robot AI isn’t ready for real work yet.

The models aren’t good enough.

75%is the best any model has done on a real robot. A production line needs 95% or more.

Why it’s stuck

Not enough real data, and it’s hard to make. That’s where B2A comes in.

There’s no easy way to scale robot training.

Today a robot learns from one of two places. Neither grows with demand.
01 · SimulationFast and cheap, but it doesn't carry over to a real robot.✕ Not real
02 · People, by handReal, but one person drives one robot through one try at a time.✕ Doesn't scale

The robot is the cheap part.

60%of a robot cell's cost isn't the robot: it's integration, programming, tooling and safety.

The solution

Rent a robot on-demand.

Put your hardware in our cell and run the same tasks and models as every other arm.

How it works From robot to report, over the internet.

  1. 01

    Pick a robot

    Choose an arm in our cell, or bring your own.

  2. 02

    Set it up

    Gripper, cameras, scene and task, plus the model you want to train or test.

  3. 03

    Run it

    Start now or book a slot. Watch every trial live.

  4. 04

    Get the report

    Success rate, failures and time per trial. Every run becomes training data.
