Most enterprise AI platforms promise adoption. Langdock is measuring it. The Berlin-based platform hit 100,000 monthly active users exchanging over 10 million messages per month – and that number reflects real, daily usage across organizations, not just license counts. For teams evaluating enterprise AI assistants right now, those figures matter.
Langdock launched in September 2023. By October 2024, it reached $1M ARR. A year later, in September 2025, it crossed $10M ARR. By December 2025, that figure had grown to $15M. The trajectory is fast and consistent – all while staying lean at 30 team members as of January 2026.
That kind of growth, especially in the European enterprise market, reflects genuine product-market fit around one specific problem: getting AI safely into the hands of every employee.
One Platform, Not Five Tools:
The pitch for Langdock is consolidation. Instead of running separate tools for AI chat, workflow automation, and internal knowledge search, companies can handle all of it inside a single platform.
The core product is a model-agnostic AI assistant that works for every employee in the company. Teams use it the same way they’d use any chat tool – for drafting, summarizing, researching, or answering quick questions. The key difference is that it connects to the company’s actual knowledge base, not just the open web.
On top of chat, Langdock includes workflow automation for multi-step AI tasks, custom AI agents built for recurring processes, and an API layer for embedding AI into existing applications. Everything runs inside one admin-controlled environment, which is what enterprise IT teams need before they say yes to any new deployment.
Security and GDPR Built in:
For European companies, GDPR compliance is a prerequisite, not a feature. Langdock is fully GDPR-compliant and hosted in Europe, which removes one of the most common blockers for enterprise AI adoption in German-speaking markets and across the EU.
The platform also gives admins centralized governance controls. Admins can see who’s using what, manage integrations, and configure access without needing to involve engineering. That matters for compliance-heavy sectors like pharmaceuticals or financial services – sectors where Langdock already has customers like Merck.
Data handling is transparent enough that Langdock maintains a public trust center for detailed security documentation. For operators doing AI vendor due diligence, that kind of transparency shortens the evaluation cycle.
Who Uses it:
Langdock is trusted by over 4,000 companies. That list includes Merck, Personio, Babbel, SumUp, Der Spiegel, The Economist, UNICEF, and Süddeutsche Zeitung – a spread across pharmaceuticals, media, HR tech, and consumer apps.
Merck’s internal deployment, branded as “myGPT Suite,” runs on Langdock and serves 33,000 monthly active users inside one company alone. That single data point illustrates the platform’s ability to scale inside large, regulated organizations – not just small teams running experiments.
For founders and operators evaluating AI platforms for team deployment, the customer list answers the “who else is doing this” question clearly.
Pricing and Access:
Langdock is priced at €23.20 per user per month. There’s a free trial available without needing to contact sales, which makes it straightforward for smaller teams to test before committing.
For larger deployments – 1,000 seats or more – enterprise-specific options include custom deployment, on-premise hosting, and white-labeling. The Merck “myGPT Suite” branding is a visible example of what the enterprise customization layer looks like in practice.
What to Focus on Next:
Langdock’s AI adoption playbook is publicly available on the website – a practical guide built from supporting hundreds of real rollouts. For any operator planning a company-wide AI deployment, it’s worth reading before writing the procurement brief.
The platform also supports MCP (Model Context Protocol) and open standards for custom agents and tools, which matters for developer teams building on top of Langdock rather than just using it off the shelf.
If your company is evaluating enterprise AI chat platforms with GDPR compliance and centralized admin controls, Langdock’s current scale – $15M ARR, 100K+ monthly active users, and 4,000+ customers by February 2026 – makes it a strong reference point for what mature AI adoption looks like in European enterprise.
