Company
— We run the GPUs so you don’t have to.
Training a model got easy. Running one did not. We started Arclight so that a team of five can serve a model to five million people without hiring anyone to babysit GPUs at 3 a.m.
How we got here
002
arc—light
2022
Three engineers and a rack
Ines, Jonah and Wei leave a large cloud to build the inference engine they wished they had, in a garage in Oakland.
2023
The first thousand teams
A public beta with one model and one region. A thousand teams sign up in the first month; most of them stay.
2024
Training and Guardrails
Fine-tuning with automatic resume, and the first policy engine that reads plain English. Series A, led by Foundry Lane.
2025
Four regions
Amsterdam and Oregon join Virginia, then Singapore. Enterprise customers bring their own clouds.
2026
Arc-7
Our own flagship model, served at 180 ms to the first token. Three thousand teams, 140 people, still answering support ourselves.
What we hold to
003
arc—light
Boring infrastructure
The best compliment we get is silence. We would rather be dull and up than clever and down.
Price on the page
Every price we charge is public. If a discount exists, everyone of your size gets it.
Your data is yours
We never train on what you send. Not in a default, not in a footnote, not ever.
Engineers answer
Support is staffed by the people who build the platform. There is no first line to get past.
