EndoBrain is a second brain for your whole company. You tell it what happened, the way you would tell a partner, and it keeps everything in one memory: clients, leads, money, invoices, promises, tax receipts. Today it tracks your money, prepares your VAT returns, writes invoices, reports and posts, and every morning brings you one move with the numbers behind it. Next it finds new clients and does the work on your word. You decide.

What it is
A second brain for the company you run.
Most of what keeps a company running lives in people’s heads. Who asked for a quote. Which invoice is still open. What you promised on Friday. Why you said no to that client in spring. Your tools each hold a piece of it. None of them holds all of it, and none of them thinks about it.
EndoBrain holds all of it. You tell it what happened in plain words, or send an invoice, a PDF or a link. It turns that into facts and links them into a map of your company: this client, that offer, this amount, that date. Every fact keeps the sentence or document it came from, so you can always ask where a thought came from.
Then it does what you have no time for. It looks at everything at once, notices what changed and comes back with the main thing, one move and at most one question. It never moves money or sends anything on its own. It proposes. You decide, and it remembers what you decided.

Tell it what happened.
After a call you write two lines, the way you would text a partner. No form, no fields, no categories to pick. A photo of an invoice, a PDF or a link works the same way.
You · 18:42
Called Atelier Weiss. They want the spring campaign, around €4,000. I promised to call back Friday.

18:43 · It connects
Every fact finds its place.
Client, offer, amount, promise, date. Each one becomes a point on the map of your company and links to what is already there: the earlier quote, last year’s invoice, the person you met. Ask why it knows something and it shows you this sentence.

02:00 · It thinks
While you sleep, it looks at everything at once.
It compares what it expected with what happened: money in and out, open invoices, leads, promises. What matches stays quiet. What doesn’t becomes a finding. A contradiction in its memory becomes a question for you. Nothing is deleted.

06:00 · It brings one move
One short brief. Then it gets out of your way.
The main thing in one sentence, one move with the numbers behind it, at most one question. If nothing changed, there is no brief at all. Anything overdue doesn’t wait for the morning: it reaches your phone as soon as it is due.
Morning brief06:00 · example
Main thing
Two September invoices are still open, €1,450 in total.
One move
Send Nordlicht a friendly reminder today. Last time, one reminder was enough.
One question
Is the spring campaign with Atelier Weiss still on for March?

Done, later or drop.
You make the call. Later brings it back in a week. Drop keeps it quiet. Every decision is remembered, with your reason if you give one, so months from now it can tell you that you turned this down once, and why.

Rules it cannot break
A business brain that can invent a number is worse than none.
Built so it can’t fool you
Numbers come from code
The model explains figures. It never writes one.
Held by A guard reads every brief. A figure the code didn’t supply sends the text back.
It proposes. You decide.
Nothing moves money, prices or messages without your yes.
Held by Every change starts as a draft with a button only you can press.
Every fact has a source
Ask why, and you get the sentence, the invoice or the page.
Held by Each point in the map stores where it came from and when.
It argues with you
When your plan contradicts your own numbers, it says so and shows them.
Held by Written into its constitution, the principles inside every thought.
Your memory stays yours
Your company’s memory is never mixed with anyone else’s.
Held by One company, one database, stored in the EU.
Who it is for
If your company runs on what people remember, it’s for you.
EndoBrain is built for any company, whatever it sells and however large it is: a one-person studio, a trade business, a practice, an online shop, a firm with departments and a board. The problem is the same at every size. What matters is spread across heads and tools, and nobody has the time to look at all of it at once.
You sell to clients and keep promises to them.
Money matters, but you don’t want to become an accountant.
You decide fast and want to see why.
Today it runs every day in one company: the web studio in Ulm where it is built. It opens to other companies one by one.
Now
Already running. Every day.
Not a concept. Everything below works today, inside the company it was built in.

Questions
What people ask first.
Is it a chatbot?
No. A chatbot answers and forgets. EndoBrain keeps every fact you give it in a map of your company, with its source, and thinks about your company when you aren’t asking. The chat is only the door you use to talk to it.
Can it act on its own?
It can remind, draft and ask. It cannot move money, change prices or send anything without your yes. That rule lives in the code, not in a promise.
Where is my data?
Each company gets its own database, stored in the EU. Tax books and receipts are kept in Ireland. Your memory is never mixed with another company’s.
Which AI does it use?
Google’s Gemini models, chosen for each task: fast ones for routine, slower ones when the stakes go up. The model reads and explains. Figures always come from code.
Does it replace my tax advisor?
No. It prepares and checks your VAT returns and flags what looks unusual. It gives no individual tax advice. You or your Steuerberater decide, and you can export everything for them.
Do I have to connect my bank?
No. Tell it about payments in chat, or import an N26 statement as a file and it reconciles the two. A direct bank connection is next.
Which languages does it speak?
The app speaks English, German and Russian. Tax forms and invoices stay German, the way the tax office expects them.
Can it be fitted to my company?
Yes. Every company gets the same core, and each early-access company is set up by hand: your offers, prices, clients and how you sell. What your company needs on top, such as your lead sources or the tools you already use, we build as a module and switch it on for you.
When can I use it?
It opens to a small circle of companies first, each set up by hand. Request early access and a person answers.
