Built by platform engineers. Governed by one rule.
Minns is agents for UK accounting practices. They keep the deadlines board, chase the records and prepare the VAT return and the accounts from the books. The platform underneath was built by people who have shipped production systems at global scale, around one rule: nothing is filed, sent or released without a named person approving it, and the record of that approval is kept.
We started with the memory: a database that keeps every fact with the dates it was true, so an agent can say what changed since last month and why. Accountants turned out to be the people who most needed an agent that remembers, shows its work and asks first.
The founders. You deal with us directly.

The controls are the product.
An agent with access to a practice's books and HMRC is an incident waiting to happen unless the controls are built in. These are the four we will not bend.
- Nothing is filed without a named person
- A return, a set of accounts, a chase, an answer to a client: each waits for a named approver. The approval is checked against the exact page and figures the approver saw, so nothing goes out on an old approval.
- Figures come from the engine, never the model
- VAT boxes, the trial balance and the accounts are computed by a double entry engine. The language model reads them and writes around them. It does not invent a number.
- The record is kept
- Every run is written down: what the agent read, what it did, who approved it and when. Facts are kept with their dates and never overwritten, so the firm can show what was true on the day it signed.
- Secrets stay out of the agent's reach
- HMRC tokens, Companies House keys and bookkeeping credentials are held in the control plane. They never reach an agent, a prompt or a workspace. Card numbers are hidden wherever they appear.
What a partner asks before anything else.
- Where it runs
- Minns runs your agents and holds your data on our infrastructure in London.
- Who you deal with
- The founders, directly. There is no sales team between you and the people who built it. [email protected] reaches both.
- Privacy
- [email protected], and the privacy policy says what we keep and for how long.
- Open source
- The memory engine, MinnsDB, is open source on GitHub.
We are looking for a few UK practices to tell us where we have got it wrong.
It is free. We set the agents up on the demo company first, then on your clients, and you tell us how it goes. The price after that is agreed with you up front, per client, before you pay anything.
