Additional users beyond the 5 included in Professional. Each extra seat adds one user and +30 uploads/mo to the workspace. Add or remove seats at the next billing cycle.
Only the cryptographic hash of each document is sent to immut for blockchain timestamping. The original file is not stored by immut. Ideal for universities and firms with strict data residency or compliance requirements.
Full white-label portal with your branding, your domain (e.g. protect.yourfirm.com), custom login, emails, and certificates. No visible immut branding.
Additional blockchain wallets to segregate compliance evidence by department, project, or client. Uploads are shared across all workspaces. No extra uploads included.

An upload is a single document added to immut that is then logged on the blockchain. This can be done manually via the web interface or via API. Note that adding a new version also is classed as an upload.
No. Both included uploads and add-on uploads reset each billing cycle. Neither rolls over. Add-on uploads are consumed after your included allowance is used up each month.
Yes. You can upgrade at any time and your billing is prorated. Downgrades take effect at the next billing cycle.
The free trial runs on testnet, which is suitable for evaluation only. Testnet data can be cleared at any time. Paid plans use mainnet, where every timestamp is permanently recorded and legally defensible.
Yes. We work closely with universities and tech transfer offices. Contact us to discuss volume pricing, phased onboarding, and data residency requirements.
