Our story
It started with our own work.
We start companies for a living. Every new product asks the same things of us: write the software, put it online, find the first customers, keep it running and decide what to improve next. AI changed how fast we could do all of it, and we used every model we could get our hands on.
Somewhere along the way we noticed a pattern. Each model has work it does best. One writes excellent code. Another thinks through a plan carefully. Another is quick and inexpensive for the simple jobs. The best results came when the right model did the right part of the work, and the next model took over where the last one left off.
So we built a stack for ourselves. It gives every task to the model that does it best, passes the work along, checks the result and runs what we build on the cloud that suits it. Our products shipped sooner, and the same work cost us a fraction of what it used to.
The model at the heart of that stack we named Maestro. We watched millions of real tasks go to real models, and every route, every check and every result went into one model. Maestro knows what each model does best, what it costs, and where it runs. It routes every task to the right model and the right cloud, checks the work, and tries again when it has to. That is ZB Stack: the best of every model, on the best cloud for each job, with Maestro finding the best way to get each task done. Every task we route makes it smarter. Maestro is an AI execution model: it gets every job done by the right models and the right agents, at the lowest cost.
Then a bigger thought took over. A student with an app idea. A nurse who knows exactly what a clinic needs. A shop owner ready to sell online. Each of them deserves the same stack we use, at a price that lets them start today.
That is why ZB Stack exists, and why we started the Zero Build Foundation beside it. The Foundation brings AI labs, cloud providers and companies together to sponsor models, so builders can use them free. ZB Stack earns 5% on the work that is not sponsored, and nothing else.
A good idea deserves a chance. We are building the stack that gives it one.
