Introduction
taos is a European Business OS that brings chat, tasks, workflows, tickets, and CRM into one app. It helps teams keep context instead of jumping between separate tools.
What is taos?
taos is an all-in-one business app and European Business OS designed for teams that want fewer subscriptions and clearer work context. It combines chat, task management, workflows, tickets, calendar, and CRM in one place. The core idea is simple: a message can become a task, a deadline, a calendar event, or a company process in one click. Comments on that task then return to the original conversation, so the reasoning stays attached to the work.
This matters because many teams already use four to eight separate tools for communication, projects, support, and client records. Those tools often lose context between modules. taos is built to reduce that fragmentation. It is also European by jurisdiction: the platform is EU made and EU hosted, with data kept in the European Economic Area. This can matter for law firms, auditors, R&D institutes, public bodies, and other organisations that need GDPR-aligned software. An open preview makes every feature free for every team until 30 November 2026, with no credit card required.
Key Features of taos
Conversation-to-task conversion
Turn any message into a task with an owner, deadline, and milestone without leaving the chat. Task comments sync back to the channel, so team collaboration stays connected to the original discussion.
Calm notifications by default
taos alerts users only where action is genuinely needed. Availability schedules, automatic Do Not Disturb during recurring meetings, and per-channel rules help reduce notification overload.
Multi-organisation inbox
Switch between clients, companies, or workspaces without logging out. Chat, tasks, boards, tickets, and CRM notifications arrive in one list, which is useful for agencies and multi-client teams.
European hosting and compliance
The platform is EU made and EU hosted, with workspace data staying in the European Economic Area. It references GDPR, the EU AI Act, the EU Data Act, and eIDAS, and can simplify NIS2 and DORA supply-chain evidence.
Boards and shared calendar
Urgent and one-off items move onto Kanban boards where priorities and statuses change quickly. Every task with a deadline appears in the shared calendar and syncs both ways with Google Workspace and Microsoft 365.
Workflows and SOPs
Turn repeatable procedures into workflow templates with predefined steps, relative deadlines, and responsible departments. This supports workflow automation and makes it clear who owns the next move.
Announcements and engagement
Post company announcements and track who has acknowledged them. Feedback Friday, kudos, surveys, and pulse surveys sit inside the channels teams already use. Managers can also track eNPS, satisfaction, and alignment over time.
CRM in development
The Business OS plan includes CRM, currently listed as in development. This points to a future customer relationship management layer inside the same European Business OS.
Use Cases for taos
Agencies and client service teams
Agencies often manage several clients at once. taos lets teams switch organisations without logging out and keeps every notification in one inbox.
Law firms, auditors, and accountants
These teams may need EU data residency and clear audit trails. taos supports European hosting and structured workflows, tickets, and task management.
Operations and project teams
Operations teams can use boards for urgent work and workflows for repeatable processes. Calendar sync helps deadlines stay visible without a second diary.
HR and internal communications
HR teams can post announcements, collect acknowledgements, run pulse surveys, and measure engagement. This makes culture part of the daily workspace rather than a separate add-on.
Public bodies and R&D institutes
European hosting and compliance references can help public bodies and research teams meet internal requirements. taos also simplifies evidence for NIS2 and DORA supply-chain reviews.
