OpenBase from €19 per user/month — Burst on demand

OpenBase is an operating system for the AI work in your company. ChatGPT Team gives every user a chat. Copilot lives in Office. OpenBase sits underneath: brand, knowledge, connectors and governance in one place, every team working on top — with Donna as chief of staff and the council as in-house experts.

Ten curated personas — CFO, Lawyer, Risk Officer, Engineer, Devil’s Advocate, Visionary, Optimist, Business Developer, CMO, Shipper. Each with an eval-tested prompt and anti-sycophancy. Donna pulls them in automatically when the domain calls for it; admins decide which personas are active in the workspace.

Slack, Gmail, Google Workspace/Drive, Outlook, Confluence, Notion, HubSpot, Jira, Asana, Shopware, LinkedIn, Meta and Google Ads. Connection via OAuth with full audit trail. Custom sources can be added on request.

Each connector you set up brings its own mandates — named proactive tasks Donna takes on (inbox triage, mentions watch, calendar brief). On Pro they are active on connect; on the trial workspace they start off and you opt in per mandate. If a mandate becomes too much, you toggle it off in the connector settings or directly on the Canvas item that produced it. The underlying tools remain available in chat.

OpenBase uses frontier models like Anthropic Claude Sonnet 4 and Haiku, OpenAI GPT-4o, Google Gemini 2.5 Pro and others — through routes we control. By default only providers with no-training guarantees on API inputs are enabled. Admins decide per workspace which models are available.

Donna understands and answers fluently in English, German and over twenty other languages. You can configure your brand voice per language.

Trial workspace free up to €15 of model usage — full product, no credit card. Pro: €19 per user/month — Donna, the council, connectors, knowledge base, mandates and hosting included, with fair inclusive limits for professional use. Heavy users enable Burst per seat; admins set a monthly cap per user. Enterprise with volume pricing, commit pricing and dedicated customer success.

Sign in with Google or Microsoft, the workspace is there. First connectors connected in two minutes. Brand voice calibrated in under ten minutes.

Workspace data (conversations, files, knowledge base) lives in Frankfurt, Germany, on Digital Ocean Managed PostgreSQL and object storage. Each workspace has an isolated schema, technically separated from every other tenant.

By default, no. The enabled AI providers run via commercial APIs without training rights. Admins can allow additional providers per workspace — the training policy of each provider is shown clearly when enabling it.

Google Workspace and Microsoft Entra ID (Azure AD) from day one. Custom SSO setups (e.g. SAML) on request on the Enterprise plan. Classic password login is not offered by design.

Full data export at any time. After cancellation, deletion within 30 days, on request with a deletion confirmation.
