Langdock is a Germany-based startup that builds a chat interface sitting between companies and large language models to prevent vendor lock-in. The interface lets companies tap foundational models, open-source models or host their own models, and supports prompt libraries and the addition of sensitive documents. Langdock also offers security, cloud and on-premises deployment options. The company is positioning itself for European customers, emphasizing secure and compliant integrations to meet EU regulation. It lists customers including Merck, GetYourGuide, HeyJobs and Forto; Merck has rolled out the interface to 63,000 employees. Langdock raised a $3M seed round led by General Catalyst and La Famiglia, with participation from Y Combinator, noted German founders and around 25 angel investors. The company is “going heavy” on its European play to help firms safely and securely integrate LLMs without locking into a single provider.
