A lead asks for help
A contact form or email creates the client record and starts the onboarding workflow.
Your business back office — private, managed, in the EU
Run your whole business
on a private EU server
reserved for you alone.
Files, documents, clients, invoicing, automation and private AI over your own data — brought together on a dedicated EU server reserved for you, not a shared application tenant. We deploy it, secure it, back it up and keep it running. You get a URL and start working: no server to administer, a fixed price within the stated user limit, and portable formats with no lock-in.
Start with your private office, then add ready-made workflows for document intake, client folders, summaries, reminders, and reporting.
Only need email, storage and office tools? A conventional collaboration suite will often cost less. ReefOffice is for organisations that also need document management, business operations, automation and isolation.

How the managed workspace works
Nextcloud, Private AI & automation, and a full open-source stack.
☁️
Your private cloud
Under the hood ▸
Runs as a native NixOS service on your own VM — not a shared container — with Collabora CODE for office documents, Talk for chat and video, full-text search and notify_push for instant sync. Backed by PostgreSQL and Redis, with single sign-on through Authentik (OIDC). The declarative NixOS config keeps the whole setup reproducible and easy to roll back.
The name says it: Nextcloud is your cloud — and the ReefOffice ecosystem grows around it. Files, shared folders, calendar, contacts, an email client, collaborative documents, chat and light calls, tasks, notes and forms stay in your reserved environment.
Get the core of Drive, Docs and Calendar in an EU environment reserved for your organisation. Each authorised member has an account and can use a browser or the Nextcloud mobile app. The mail client connects your existing address; ReefOffice does not provide the mailbox.
Files & foldersCalendarContactsMailCollaborative docsChat & videoTasks & boardsNotesFormsMobile appTeam sharing
Nextcloud runs on 500,000+ servers worldwide and is trusted by serious organisations across Europe — including the German federal government, the city of Stuttgart, and EU public bodies.

Private AI & automation
Under the hood ▸
Open WebUI gives a private, ChatGPT-style chat. Hermes, the autonomous agent, runs on every plan — it uses a private ReefOffice GPU model (in Germany) on Private AI plans, or your own API key (Mistral, OpenAI, Claude…) on Private Office plans. Search runs on Qdrant with the local bge-m3 model, so indexing and retrieval never leave your server. Advanced automation is built in too, while the ReefOffice-maintained recipes run in a separate, operator-only runtime so they never expose their credentials.
Every plan uses a private AI model to turn your files, documents and notes into a knowledge base you can ask in plain language.
For written answers — summarise last month's invoices, find a clause in an old contract, or draft a proposal from your last one — connect your own AI key (for example Mistral · OpenAI · Anthropic), or use a Private AI plan to run powerful AI models on a ReefOffice GPU in Germany and use them through a chat interface (Open WebUI) or the ReefOffice AI agent (Hermes).
On top of that, a preinstalled, secure automation layer plus your own automations turn ReefOffice into your ultimate productivity workspace.

Everything included
Under the hood ▸
ReefOffice configures your selected applications declaratively on a VM reserved for your organisation. Authentik provides one sign-on for compatible apps, nginx handles automatically renewed HTTPS certificates, and encrypted Restic backups are stored with an EU provider. Each customer has a separate VM, while documented exports and open formats make moving away practical.

FAQ
Common questions
Do I need technical knowledge to use ReefOffice?
No. Setup is handled entirely by us — you receive a URL and a login, and your team can start using the services immediately. The dashboard lets you enable or disable services with a toggle. We manage updates, security patches, and backups in the background. You never need to touch a terminal.
What is the difference between the plans? Is anything shared?
Every plan gives you your own server in the EU — your machine, your storage, your data, isolated from all other clients. Solo plans are for freelancers; Team plans add collaboration tools. See the comparison table above for plan-by-plan details.
Do I need to pay extra for AI? What's the difference between Private Office and the Managed EU AI add-on?
Yes. On Private Office plans (€39–€99/mo), document search and the private chat interface are included, but written AI answers need your own API key from a provider such as Mistral, OpenAI, Anthropic or Gemini. You connect it in the dashboard, and only the text you explicitly send reaches that provider; your stored files remain on your ReefOffice server.
On Private AI plans (€99–€199/mo), Hermes is the default AI agent workspace and the AI runtime is included. No external key is needed for the normal workflow.
Simple rule: Private Office = bring your own AI key for written answers. Private AI = built-in AI with Hermes by default.

What happens if I want to leave?
You own your data. You can export everything from Nextcloud at any time (standard WebDAV + export tools), and we provide a docker-compose.yml so you can run the full stack on any server yourself. There is no proprietary format, no lock-in, and no exit fee.
Ready to make your data yours?
Your private office, running in the EU, managed for you.
🔒 Built for privacy — not just compliant with it
Your data lives on a server only you use. The disk is encrypted, backups are encrypted before they ever leave the server, and logging in requires 2FA (a second step beyond your password — like a one-time code from your phone). Every behind-the-scenes action used to manage your server is saved to a tamper-proof log. Normal backups let ReefOffice help you restore if something ever goes wrong; or you can choose to hold the only backup key yourself once we hand the server over to you. Hosted in the EU, GDPR by default.
