Tools everywhere, no shared foundation
ChatGPT Team here, Copilot there, Notion AI somewhere else. Each one needs a fresh briefing, knows a fraction of your reality, shares nothing with the others.
Every team has AI. None of it makes the company smarter. This is the layer that does.
Can you analyze our Q4 revenue data and identify the top 3 growth drivers?
Based on the Q4 data, the three primary growth drivers were:
1. Enterprise expansion (+34%) — 12 new accounts
2. Self-serve upgrades (+22%) — driven by the new tier
3. DACH region (+18%) — strong Mittelstand adoption
Great — can you break down the enterprise segment by region?
The problem
Marketing uses ChatGPT. HR tries Copilot. Sales buys Gemini. Everyone solves their own problem on their own account. Knowledge stays with the person, brand consistency drops, costs spread across ten invoices — and the company is no smarter for it.
ChatGPT Team here, Copilot there, Notion AI somewhere else. Each one needs a fresh briefing, knows a fraction of your reality, shares nothing with the others.
Generic AI gives generic answers. Without your brand, your decks and your CRM, every text reads like every other company. Employees rewrite by hand.
What one person figures out, they keep. Nobody sees who uses which model for what, what it costs, whether it is compliant. AI adoption without governance is shadow IT at premium prices.
Features
Brand, knowledge, tools and permissions live once in the workspace. Every area uses them automatically; every team works from the same state.
Donna is the chief of staff who knows your company and runs the work. On hard questions, she pulls in the right council member — CFO, Lawyer, Risk Officer, CMO or Devil’s Advocate. Curated, eval-tested, anti-sycophancy by default.
Slack, Gmail, Google Workspace, Outlook, Confluence, Notion, HubSpot, Jira, Asana, Shopware, LinkedIn, Meta, Google Ads. Your data stays where it lives — OpenBase reads through secure OAuth connections with a full audit trail.
Upload brand guidelines, decks, contracts and notes — or index connected sources. Answers come with source references and in your tone, configured per language.
Each connector ships its own mandates — inbox triage, mentions watch, calendar brief. Active on connect, toggle off individually when noisy. External actions still require explicit approval.
Full marketing projects from briefing to social post, live dashboards from your operational data, images in your brand style with identity and composition control. All versioned, approved, in the workspace.
Per-user and per-model usage and cost analytics, model whitelisting, full audit log, custom council personas on request. One central place instead of five shadow accounts.
Donna & the council
Donna knows your brand, your data and your permissions — and runs the work without you having to brief from scratch every time. When the question gets hard (investment, contract, irreversible move), she pulls in the right council member automatically. Ten curated personas with eval-tested prompts and anti-sycophancy by default.
Every connector you grant Donna brings its own mandates: inbox triage with Gmail, mentions watch with Slack, daily brief with Calendar. Named, individually revocable, with explicit approval for any external action.
Knowledge & connectors
Upload brand guidelines, pitch decks, contracts and notes directly — or connect Slack, Gmail, Drive, Confluence, Notion, HubSpot, Jira, Asana and Shopware. Donna and the council all draw from the same sources; every answer comes with source references.
How it works
No setup, no week-long onboarding. The workspace is ready after the first sign-in. As soon as your tools are connected and your brand is calibrated, OpenBase runs with the real context of your company.
Google Workspace or Microsoft Entra ID. Your email domain is mapped to your workspace automatically. New domain? Workspace provisions in seconds.
Slack, Gmail, Drive, Confluence, HubSpot, Jira, Asana — connected via OAuth with a full audit trail. Upload brand guidelines, decks and notes directly, or have connected sources indexed.
Marketing writes in your brand voice. HR finds the Confluence answer that actually applies. Operations runs routines, IT sees every action in the audit log. No more tool sprawl.
Your workspace environment
Identity, knowledge, tools and rules live once — every area and every team works on top.
Brand voice, knowledge base and connectors live once in the workspace. Marketing, HR, Sales and Operations work from the same state — no briefing ping-pong between tools.
Google Workspace or Microsoft Entra ID. Sign in, you are in. No password vault, no invitation links, no provisioning tickets.
EU hosting in Frankfurt, tenant isolation at the database level, full audit log. There so OpenBase can be deployed everywhere in the company — not what we sell on.
Who is this for?
Brand voice baked in, image generation in your visual style, creative briefings in the same workspace. The CMO from the council reviews the headline before it ships. No more ChatGPT outputs that do not sound like you.
A knowledge base that actually finds what is in Confluence. Donna writes reports, summarizes reviews, runs routines — with approval workflows for anything that goes outside.
One central platform instead of five shadow tools. Per-user and per-model usage and cost analytics, model whitelisting, full audit log. You can see exactly where your data lives — IT does not have to sign off begrudgingly, IT finally gets visibility.

FAQ
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.
The difference is context. OpenBase knows your brand, your data and your permissions. Donna runs the work, the council pushes back when it should — curated, eval-tested, with anti-sycophancy by default.
One platform for every team in your company, not one chatbot per department. Decisions get captured. Outputs sound like you. IT sees every action.
Sign in with your company account. Workspace is ready in seconds — no setup, no credit card.
Trial workspace — full product up to €15 of model usage. No credit card required.
