For firms · one vault, never leaves the building

the case

An archive on someone else's machine is a tenancy, not a holding.

Your people are already pasting the firm’s work into machines you do not run. That is Shadow AI, and it is a leak. When someone leaves, what they knew leaves with them. That is corporate amnesia, and it is expensive. And if it ever came to it, could you prove a record has not been touched since the day it was made?

A vault on your own hardware answers all three. The knowledge stays when staff leave. The machine that reasons stays on your side of the wire. Every record is sealed the day it is made, and anyone you show it to can check it without us. Practices, chambers, advisers, family offices, agencies, clinics, libraries, orders: the firms with something worth keeping.

What you getone product · three records

№ 01the vault

The vault.

One vault for the whole firm, as plain files, on the firm’s own hardware.

what it isA folder of plain files on a machine the firm owns: a file server, or a Mac in the office. Each person installs the app on their own Mac and points it at that folder. Nothing of the firm’s passes through us, and we hold no copy.

each personMakes their own signing key on their own Mac. The seal on what they make says who made it. The firm’s key vouches for each person and puts the firm’s name on the seal.

you receiveThe shared vault, the firm’s key and the seals it vouches for, and the survey desk: a person reads it, a person answers.

todayNot shipped yet. The vault reads plain text and markdown. PDF, Word, mail and meeting transcripts come with the import. One vault opened by several people, the firm’s key, and the firm’s name on the seal are not built.

The seat.

£240 a seat a year. Two seats or more.

a seat isOne person who opens the firm’s vault with their own key. Everyone who opens it counts, reader or writer. Your own Macs are not seats. A practice, a household or two people who work together pay the same: one price, whoever buys.

the figures£240 a seat a year. The least a firm can buy is two seats, £480 a year. One invoice a year, paid in advance. No setup charge, and the same price for every firm at every size. Third ARK Limited is not registered for VAT, so no VAT is added. /pricing

the modelYou supply it. A local model costs nothing. A cloud model runs on your own key and your own bill.

when it endsEvery file stays where it is and stays readable. Each person carries on with the free vault. What stops is adding people and sealing in the firm’s name. Nothing is locked and nothing is deleted.

todayNot on sale yet. It goes on sale when two things ship: the import of PDF, Word, mail and meeting transcripts, and the vault shared by several people. We take no money until then.

№ 03the ten minutes

The ten minutes.

Before any seat is bought, in your boardroom.

what happensWe point ARK at one folder of your own documents, on a Mac in your room. A partner asks a question; the answer names the document. We turn the network off and ask again. We seal one record and break it.

the shapeNothing is sold in the room, and it costs nothing. If you want seats, we write the next day with what must ship first.

todayNot offered yet. We offer it when the import ships, so the folder in the room can be the one the firm already keeps.
