The CRM for freelancers and small businesses
No more separate mail program, to-do list and timesheet. In Gatun Organizer everything hangs off your clients: mail, tasks, projects, files and hours.

Mail with the right client
Connect your mailbox and mail to and from your clients automatically lands with the right relation, by address or by domain. Mail that doesn’t belong anywhere yet goes to an existing or new relation in one click. Replying and scheduling mail to send later both happen in Gatun Organizer.
Let the AI read along (optional)
Turn on classification and a language model sorts new mail: default categories such as Invoice, Quote request and Support/question, which you can adjust yourself. If the model is unsure, it passes the mail to you to review; where it fits, it suggests a task. The model runs at Scaleway in Paris, stores nothing and does not train on your mail.
Rules that do the work
A rule turns an invoice email into a task for the bookkeeping, sends a colleague a notification, or clears out newsletters after a month. Company rules for everyone, and personal rules for each employee.
Tasks and projects
Tasks on a board with columns, deadlines, labels and comments. A project brings tasks, files and hours together, with a timeline and its progress.
Logging hours
Week sheet, single entry or timer — on a task, project or relation. Overviews per project (against the budget) and per relation (billable or not), which you can export to CSV or Excel.
Calendar
A shared calendar with invitations; colleagues’ private appointments only show as busy. Also in Outlook, Apple Calendar or on your phone. From an appointment you log your hours straight away.
Files
Folders per company, relation and project. Open a document straight in Word and save it there again. From your phone you share a photo or PDF straight to the right folder.
Working together
Invite colleagues as Admin or User. The Owner and Admins manage mailboxes, members and settings; everyone can use two-factor authentication.
Integrations
Let an AI assistant such as Claude work in your CRM on your behalf, or create an API token for your own scripts — always with only the permissions you choose.
