What we are building
A home with Vision for questions and tasks, one place for what happened, and the tools a firm already uses, each with its state. Shown here as the current prototype.

Views of the current prototype, with Orsenne & Associés, a fictional example firm, and fictional data. Stackeo is not open yet.
Why one workspace.
One place to start
The home holds Vision’s composer and Today’s list: what to ask and what to do, nothing else.
One channel for attention
Events go to the bell, duties stay on the home, so reading a notification never hides a deadline.
Your tools, connected
Connectors are designed to bring mail, files and ledgers to Vision, and to say when they need you.
Three surfaces. In the current prototype.
Vision, on the home
Ask in your own words; choose Chat for an answer or Work for a task. Vision is designed to say what it read and to wait for your yes before acting.
- Sources beside each answer, by design
- An AI notice where you type
- The asker’s rights, never more (our rule)

The notification centre
What happened, grouped by day or by dossier, with filters for unread items, mentions and deadlines.
- Snooze, archive, undo
- Keyboard shortcuts and swipe, each also in a menu
- Each row led by its source

Connectors
Accounting, office, legal and public data sources in one catalogue, each card with its state and its last sync.
- Errors with the provider’s answer and the time
- Every change recorded with its author
- Monograms until each brand allows its logo
Moments we design for.
- Accounting
The VAT week
The home lists the returns due this week.
- Accounting
Missing documents
Vision prepares reminder drafts; a person reads and sends them.
- Both
A key refused
The connector says so, with the time and what to do.
- Law
A lease under review
Questions on a document, answered with its sources, by design.
- Law
Mentions and dates
A colleague’s question and a deadline in one notification centre.
- Both
Public data
Légifrance and INSEE SIRENE in the connector catalogue.
Your clients’ secrets come first.
Before any feature, the founders wrote the rules Stackeo must follow. They bind everyone who builds it:
Our rules for your data- Each firm isolatedNo firm may reach another’s data. In the version being built, every boundary has a test that tries to cross it.
- Vision with your rights, never moreVision must act with the permissions of the person asking; sensitive actions wait for a person’s yes.
- No access by our team by defaultSupport access must be explicit, limited and recorded. Running the platform never means reading your content.
- Sensitive actions recordedSensitive actions go to an audit log.
- AI under a business contractThe AI models that serve firms go through providers’ APIs or business agreements, never personal subscriptions.
- Hosting in Paris, being validatedOur current choice: Supabase on AWS, region Paris (eu-west-3). It is not final until the contracts are signed.
Questions, answered.
ContactWhat is the difference between Chat and Work?
In the prototype, Chat answers a question in the conversation; Work takes on a longer task and shows its progress.
Why both a bell and a « Today » list?
The bell lists what happened and clears once read. « Today » lists what must be done and never disappears by being read.
Is what we see the real product?
It is the current prototype, with a fictional firm and fictional data. Stackeo is not open yet.
