About Fainite
Everything humans build is driven by simulation: the shape of a turbine blade, the structure of a chassis, the cooling path through a battery pack. And simulation is still painfully slow: millions of engineers wait hours or days for a single run, forcing them to explore just a few designs when the best one may lie in the thousands they never reach. Replacing simulation with direct prediction is one of the great unsolved problems in AI.
Our answer is a foundation model for hardware engineering: a large-scale physics AI model that turns simulation into inference, collapsing hours into seconds. One model across the full lifecycle of a physical product, from design through engineering to manufacturing. The ambition is simple: become the AI infrastructure underneath how the world builds hardware.
We're a tight-knit team in Zurich, with engineers from Caltech, Google, CERN, and ETH working alongside a professor from Cambridge. Ideas go from whiteboard to training run in a day, and everyone touches everything.
18 million
Engineers worldwide, and every physical product they ship runs through simulation before it's built.
$27 billion
Simulation software market today, still built on solvers that take hours or days per run.
2× by 2030
The market is projected to roughly double over the next five years, growing 10–13% every year.
50% faster to market
Design cycles that took months compress into weeks when simulation runs in seconds instead of days.
