Subprocessors
November 4, 2026
These are the companies we use to provide Kolophi. Only Google Cloud stores or processes your firm's records. All processing is in the United States.
| Company | What it does for us | What it receives |
|---|---|---|
| Google Cloud (Google LLC) | Hosts each firm's Kolophi install: its server, disks, backups and secrets. Runs the Claude model through Vertex AI. | Your firm's records and its users' details, stored in your install; the text of documents sent to the model |
| Anthropic, PBC | Makes the Claude model, which runs on Google Cloud's Vertex AI for us | Nothing from Kolophi directly. Kolophi uses Claude only through Google Cloud. |
| Microsoft Corporation | Kolophi's email, and the Microsoft sign-in your people use | Emails to and from Kolophi; sign-in requests. Not your records. |
| Stripe, Inc. | Takes payments and sends invoices | Your billing contact, billing address and payment details. Not your records. |
| Cloudflare, Inc. | Hosts kolophi.ai and the address records for each install | Visits to kolophi.ai. Traffic to your install doesn't pass through Cloudflare. |
Changes
We'll email your administrators at least 30 days before adding or replacing a subprocessor that would receive your firm's records. If you object, you may cancel before the change and we'll refund any fees paid for the time after it.
