We are making
reality programmable.

Software ate information. Physics is next.

$10.5B

invested into world models in twelve months.

The physical economy is the last thing software hasn't eaten.

Eighty-five trillion dollars of GDP comes from physical things. Built, designed, refined, transported. All of it has moved at the speed of human iteration. Weeks of CFD per blade. Decades per drug. Lifetimes per material.

World models collapse the loop. A simulation that used to take a day and the electricity of a small town runs on a single GPU in minutes. The cost of asking "what happens if" approaches zero. The rate of physical innovation goes from generational to weekly.

Whoever owns the world model owns the next fifty years.

Global state of the art. Against every incumbent.

We trained on weather. We tested on wind tunnels. It worked.

One model. One set of weights. Three different physics.

One agent. Three pieces of reality. Same architecture. Same weights.

01
Jua platform

The agent runs energy markets.

Across five continents, every hour. It queries the world model, prices moves, and surfaces what matters. Energy is the first physical market the agent touches at scale.

02
Jua employee quant fund

The agent wagers on reality.

Same agent, new objective, no rewriting. We pointed it at weather contracts on Polymarket. It made money from day one. The objective function is a parameter; the agent is universal.

03
Recursive

The agent improves itself.

Pointed at our cluster, the agent designs experiments, dispatches them, evaluates them, and trains the next world model. The recursion is closed.

We are going to design every physical thing.

A jet engine designed in a week.

A fusion reactor iterated in days, not decades.

New alloys discovered without a single experiment.

A power grid that never fails.

Aircraft with half the fuel burn.

A drug designed in months, not decades.

Built with ETH Zurich, Google Research, and the ETH AI Center. Backed by the founder of The Climate Corporation and executives from DeepMind and Meta.

Research from Jua and our team. Peer-reviewed at NeurIPS and ICLR.

Marvin Gabler
Marvin Gabler · Founder & CEO

It started with a kid who could not stop simulating worlds.

Marvin grew up in Germany modding games and building models of his home city. He studied biotech and computer science, dropped out of RWTH Aachen, and at 22 founded and sold his first company.

While later building simulations on classic supercomputers in his family business, one thing became obvious: if forward physics ever becomes cheap, everything physical gets redesigned. Every blade, every molecule, every material. Deeply inspired by Schmidhuber's Learning to Think, he waited for the hardware to catch up. When GPT-3 came out and chips were finally fast enough, he started Jua.

Six startups. Zero to ten million ARR. Then Jua.

Ben has spent the last decade scaling six different startups from zero to ten million ARR. When he is not in the office or at home with his wife and two boys, he is training for his next Ironman.

Roberto Molinaro
Lead Researcher

From the lab where AI for physics started.

Roberto did his PhD under Siddhartha Mishra at ETH Zurich, one of the people who pioneered AI for physics. He has published leading work on foundation models for partial differential equations — research that showed learned models can do for physics what LLMs did for text.

The foundation layer of the physical economy is being built now.

Whoever owns the world model owns the next fifty years. We are building it in Zurich.
