Langdock

What Is Langdock?

European compliance teams face an uncomfortable reality: the most capable AI assistants — ChatGPT, Copilot, Claude — process data through US-based infrastructure subject to CLOUD Act jurisdiction. For organisations bound by GDPR, financial regulations, or internal data governance policies, this creates a hard barrier to adoption. Langdock exists to remove that barrier.

Founded in 2023 by Jonas Beisswenger, Tobias Kemkes, and Lennard Schmidt, Langdock is a Berlin-based platform that provides enterprise teams with access to all major LLMs through a single GDPR-compliant interface. GPT-4, Claude, Mistral, Llama, Gemini — all accessible from one workspace, with all data processing happening exclusively on EU infrastructure. The platform reached $15 million in annual recurring revenue by December 2025, serving over 600 enterprise customers with a team of approximately 36 people.

Langdock graduated from Y Combinator and has positioned itself not as an AI model company, but as an AI access and governance layer. The platform covers three core capabilities: chat with AI assistants, automated multi-step workflows, and enterprise knowledge search across connected tools. Think of it as the compliance-friendly middle layer between your team and the world's best AI models.

Key Features

Multi-LLM Chat and Assistants

Langdock's core product gives every team member access to multiple AI models through a unified interface. Users can switch between GPT-4, Claude, Mistral, Llama, and Gemini within the same conversation — testing which model handles a specific task best without managing separate subscriptions. Custom assistants can be built with specific instructions, knowledge bases, and tool access, then shared across the organisation. The @ mention system lets users invoke integrations and data sources directly within conversations, pulling context from connected tools without leaving the chat interface.

Workflow Automation

Beyond conversational AI, Langdock offers a workflow engine for multi-step automated AI processes. Teams can build pipelines that chain together model calls, data transformations, and integration actions — automated document processing, report generation, customer inquiry routing, and similar operational tasks. The Business workflow tier supports up to 40,000 runs per month with unlimited steps per workflow. Each workflow maintains execution history and logs for auditability, which matters for regulated industries that need to demonstrate process governance.

Enterprise Knowledge Search

Langdock connects to 45+ enterprise tools via OAuth and API integrations, including Google Drive, Confluence, Notion, SharePoint, Slack, Salesforce, Jira, and HubSpot. Once connected, the AI can search across these data sources to ground responses in organisational knowledge rather than relying solely on its training data. This transforms Langdock from a generic AI chat tool into a knowledge-aware assistant that understands the company's specific context, documents, and processes.

Security Architecture

Every aspect of the platform is designed around EU data sovereignty. ISO 27001 certification and SOC 2 Type II attestation are independently verified, not self-declared. SSO, SCIM, and SAML support integrates with existing identity management. Role-based access control and audit logs give administrators visibility into who is using AI, with which models, and on what data. For organisations requiring even tighter control, dedicated hosting and on-premise deployment options are available.

Pricing

Langdock's pricing structure has three layers: Chat & Agents, Workflows, and API usage. The base Chat & Agents plan costs EUR 23 per user per month on annual billing (EUR 29 monthly), with all features included — there is no feature-gated tier ladder. Workflow automation is an add-on: the Pro tier at EUR 119 per workspace per month covers 2,500 runs, while the Business tier at EUR 449 per workspace per month supports 40,000 runs. API access incurs additional per-token charges that vary by model.

A 7-day free trial with no credit card required lowers the evaluation barrier. Enterprise pricing is custom and includes on-premise deployment, white-labelling, and dedicated account management.

For a team of 50 users on annual billing, the base cost is approximately EUR 1,150 per month before workflow and API charges. That compares favourably to 50 individual ChatGPT Plus subscriptions ($1,000/month) while adding EU compliance guarantees, centralised governance, and multi-model access. The workflow add-on pricing can add up quickly for high-volume automation use cases, though.

EU Compliance & Privacy

Langdock's compliance credentials are among the strongest in the enterprise AI category. As a German GmbH headquartered in Berlin, the company operates under German and EU data protection law. All data processing occurs on EU-only infrastructure with no transatlantic data transfers for core platform operations.

ISO 27001 certification covers the information security management system. SOC 2 Type II attestation verifies that security controls have been operating effectively over time, not just designed appropriately. These are independent third-party audits, not self-assessments.

The platform supports zero data retention configurations, meaning prompts and responses can be processed without being stored. For organisations in financial services or healthcare, this capability can be decisive for regulatory approval. SSO via SAML and SCIM integration ensures that AI access is managed through existing identity governance frameworks.

Who It's Best For

European enterprises needing AI adoption with compliance guarantees — particularly financial services, healthcare, legal, and public sector organisations where GDPR and data sovereignty are non-negotiable requirements.

Teams wanting multi-model access without vendor lock-in — the ability to switch between GPT-4, Claude, Mistral, and others from one interface avoids dependence on any single AI provider.

Organisations with rich internal knowledge bases in tools like Confluence, SharePoint, or Google Drive that want AI assistants grounded in company-specific context, not just generic model knowledge.

Not ideal for individual users, very small teams, or organisations primarily needing coding assistance. Langdock is built for broad enterprise AI adoption, not developer-specific workflows.

The Verdict

Langdock solves a specific and growing problem: how European enterprises can adopt AI assistants without compromising on data sovereignty or compliance. The multi-model approach is genuinely useful — no single LLM is best at everything, and the ability to switch providers without changing tools has strategic value. ISO 27001 and SOC 2 Type II certifications provide the audit trail that procurement teams require. The main caution is cost complexity: base subscription plus workflow add-ons plus per-token API charges can make total cost of ownership harder to predict than simpler per-seat models. For organisations where EU compliance is a hard requirement, Langdock is one of the strongest options available.
