Diligence you can check, in one place
When a seller sends you a Arrhis link, the numbers come straight from their Stripe, Mercury and Google Analytics accounts, each with its source and last sync time.

One login across deals
Every link a seller sends you lands in one buyer account, with your stage in each deal. No new password per data room.
Every number says where it came from
A brass seal means the figure was pulled from Stripe, Mercury or Google Analytics. An outline mark means the seller uploaded it.

You can see how fresh it is
Each source shows its last sync. A feed that stopped updating looks different from one that synced this morning.
Your NDA details, saved
Your legal name and firm stay on your account. The next NDA is review, tick, sign.
Verify your ID once, if you want
An optional passport or licence check, run by Stripe Identity. Sellers see a verified mark next to your name. The document never reaches us.
