About Langdock

Langdock was founded in 2023 in Berlin, Germany, by Jonas Beisswenger, Tobias Kemkes, and Lennard Schmidt, and was part of Y Combinator's Summer 2023 cohort. The company has raised $3.5M in seed funding led by General Catalyst and La Famiglia, and has grown to serve over 2,000 companies across Europe and beyond, including enterprise clients such as Merck. Langdock's core mission is enabling organisations to adopt generative AI securely and compliantly without compromising on data sovereignty. The platform provides three main product areas: a ChatGPT-like interface that connects employees to multiple LLMs (including GPT-4o, Claude 3.5 Sonnet, Gemini, Llama, and Mistral), a no-code assistant builder for creating custom AI assistants embedded with company knowledge and connected to enterprise data sources, and a workflow automation engine for building multi-step AI processes. This breadth makes Langdock a genuine all-in-one AI platform for enterprise teams rather than a single-purpose tool. Langdock's compliance posture is its primary differentiator for European enterprises. The platform is ISO 27001 certified, SOC 2 Type II audited, fully GDPR-compliant, and hosts all application data within the EU by default. Crucially, customer data is never used to train or improve any AI models, and model inference can be configured to run exclusively within EU infrastructure. Organisations can also bring their own API keys for LLM providers and optionally self-host the Langdock application within their own cloud infrastructure for maximum data control. Pricing is offered in EUR: the Business plan costs €25/user/month with SSO, SCIM, and SAML controls, while Enterprise plans are custom-priced and include dedicated infrastructure and security controls. A 7-day free trial is available. For European organisations — particularly those in regulated sectors such as pharmaceuticals, financial services, legal, and government — Langdock provides a uniquely strong combination of EU data residency, multiple LLM access, enterprise governance, and a genuinely GDPR-native architecture.
