Company
Arcois
We build software that fixes the problems teams hit running S3 at scale, on the storage they already own.
What we build
Exera, an S3-compatible gateway that sits in front of the object storage you already run, and a tape archive service for long retention. Both come from the same experience: running S3 at scale is harder than it should be, and fixing it should not mean replacing the storage you already own.
We are engineers who have run large object stores for banks, telecoms and public bodies, and have met every problem on the home page in production.
Your data stays yours
Exera runs in your environment. Objects stay on your stores, metadata in your cluster. The product does not connect to Arcois: no telemetry, no update check. The only data that ever reaches us is a support bundle you choose to send.
Built for regulated buyers
Data residency rules ask for primary and secondary systems on your own ground and for a second copy that fails independently. Exera is designed to be deployed inside those rules, not around them.
How we sell
Commercial licence with support. A pilot comes with a joint install and a written runbook. Every number we publish is one you can reproduce on your own cluster.
