We believe your data belongs to you
Fil One was built by the team behind Filecoin, the world's largest decentralized storage network. We make cloud storage you can verify, access without egress fees, and leave anytime, because your data should belong to you.

Why we built
Fil One
If you store serious data in the cloud, you know the bargain: your provider promises eleven nines of durability and asks you to trust it, egress fees punish you for using your own data, and staying longer only makes leaving more expensive.
We built Fil One because that bargain is backwards. Every file gets a cryptographic fingerprint, verified independently, so durability is something you can check, not a claim you have to trust. Pricing is one flat rate with zero egress fees, and because everything is S3-compatible, moving to or from Fil One is an endpoint change, not a migration project.
Behind the product is the team behind Filecoin, the world’s largest decentralized storage network, live since 2020 with thousands of independent operators and exabytes of proven capacity. It’s the same infrastructure trusted by the Internet Archive and the Smithsonian, so your data never depends on any single company staying honest. Not even us.
The principles behind everything we build
Your data belongs to you
You hold the keys and set the rules. We're custodians of your data, never gatekeepers.
Trust is proven, not promised
Every object carries a fingerprint, verified independently: proof, not promises.
Leaving should always be free
No egress fees, no proprietary formats. The exit door always stays open.
The team
Fil One is led by a distributed team of infrastructure veterans, technologists, and policy experts.
