A company brain is a store of what your business knows, kept outside the chat window. The facts pulled from your systems, where each fact came from, the rules you have taught it, and the record of what was approved and sent. The AI reads from it. It does not own it.
That is the part of Harness that is not about invoices: a business brain that works with the AI you already pay for, and you are early to it. Chasing is the first job it does. The memory is what makes the second and third job cheap.
Invoices, payments, quotes, threads and contacts, read from the apps you connect. Every fact carries the app it came from and the date it was read, so you can check it rather than trust it.
Who never gets chased. Which account the finance director handles personally. What tone you use with a client of ten years against a new one. Written once, applied every night.
Which person belongs to which account, who pays, who signs off, and what was last said to them. So a chase reads like it came from someone who knows them.
What was drafted, who approved it, when it went out and what came back. That is the record you need when somebody says they never heard from you.
ChatGPT and Claude both remember things now. That memory sits with one account and one history. It is fed by whatever somebody typed, it has no source you can check, and it leaves with the person who owns the login.
A company brain is fed from your accounting software and your inbox instead. Every fact has a source. The same memory answers the owner, the office manager and the bookkeeper, and it stays when somebody leaves.
You do not re-explain your business every morning. You do not paste the same customer history into a new chat. And when you ask why a chase was worded that way, there is an answer with a date on it.
Harness sits between your apps and the AI. It is not another model. The facts, the sources, the rules and the approval log live in Harness, so moving between supported ChatGPT and Claude connections does not start that memory again. You connect the new chat through MCP and carry on.
Two buttons keep it yours. Export my memory gives you everything Harness holds about your company as one file. Disconnect and forget removes everything it learned from a mailbox or from your books. You can see the switch working for yourself on the trust page.
The AI reads and drafts. It has no send button. Whichever model is answering, drafts wait for you to approve, edit or skip.
A company brain, or business brain, is a store of what your business knows, kept outside the chat window. It holds the facts pulled from your systems, where each fact came from, the rules you have taught it, and a record of what was approved and sent. The AI reads from it. It does not own it.
ChatGPT memory belongs to one account and one chat history, and it disappears if you change tool or the person leaves. A company brain belongs to the company. It is fed from your accounting software and your inbox rather than from what somebody happened to type, every fact carries its source, and the same memory answers whoever asks.
Facts read from your connected apps, such as invoices, payments, quotes and threads, each with the app and date it came from. The rules you set, such as who never gets chased and what tone to use. Relationships, meaning which contact belongs to which account and what was last said to them. And the approval log: what was drafted, who approved it, and what went out.
The memory stays. Harness sits between your apps and the AI, so the facts, sources, rules and approval log live in Harness rather than in ChatGPT or Claude. You connect the new chat through MCP and carry on. Export my memory gives you the whole of it back as one file, and Disconnect and forget removes what was learned from a mailbox or from your books.
No. The AI reads the memory and drafts. Anything that leaves the building waits in a queue for a person to approve. That rule does not change with the model you pick.
In the UK, in Heoka's own hosting, and it is not used to train anyone's model. If a customer contract of yours says data may not leave the UK, tell us before you connect anything and we will go through it with you.
Connect Xero and your email. Harness works out overnight who is overdue and by how long, drafts the chase in your tone, and queues it for you. Everything it learns doing that is the start of the company brain.
