Substrate / Company
Everyone is building models. We build the ground they stand on.
The last decade of software ran on cloud infrastructure nobody thinks about. The next decade of AI needs the same thing, and that is the only thing we build.
Infrastructure is a discipline, not a feature.
We started Substrate because the teams shipping the most interesting AI were spending most of their time not on AI, but on GPUs, kernels, and capacity. That work is real, and it is hard, and it should be somebody's whole company. It is ours.
We don't ship a model. We don't compete with your product. We do one unglamorous thing exceptionally well, and we intend to be the reason your inference just works, quietly, for a very long time.
Buttoned-up, on purpose.
Latency is a promise
A number on a slide is marketing. A number in production is a promise. We publish the ones we keep.
Boring is a feature
Infrastructure earns trust by not surprising you. We optimize for the absence of incidents, not the presence of headlines.
Own the hard layer
We build our own silicon and run our own fleet because the savings and the speed live there. Not in a wrapper.
Two decades of shipping infrastructure.
Dr. Renn Okafor
Built inference systems at hyperscale before founding Substrate. Believes the best infrastructure is invisible.
Mara Sølvberg
Twelve years designing accelerators. Leads the team that makes the chip do one thing perfectly.
Ilya Berestov
Ran reliability for a top-five cloud. Measures success in incidents that never happened.
Build the layer AI runs on.
We're hiring engineers who think infrastructure is the interesting part.
