As the AI revolution gains momentum, many large corporations remain hesitant to commit fully to any single foundational model. The apprehension stems from concerns about being tied down to one platform prematurely. Recognizing this market need, Langdock has positioned itself as the intermediary between companies and large language models (LLMs), offering a solution that enables firms to navigate LLM selection without enduring long-term commitments.

Founded in Germany, Langdock has recently closed a $3 million seed round, spearheaded by General Catalyst, with participation from its European seed-stage partner, La Famiglia. Lennard Schmidt, co-founder and CEO of Langdock, emphasizes the importance of avoiding vendor lock-in, stating, “Companies don’t want to have a vendor lock-in on just one of those LLM providers.” Langdock’s chat interface abstracts this concern, empowering companies to select from various underlying models offered by different vendors.

In addition to enabling access to foundational models, open source alternatives, or proprietary models hosted internally, Langdock’s chat interface provides a versatile solution for businesses. Schmidt highlights, “Our interface allows a company to choose which of the underlying models from different vendors can be used by employees.

The funding round attracted backing from prominent entities such as Y Combinator, as well as notable German founders including Rolf Schrömgens (Trivago), Hanno Renner (Personio), Johannes Reck (GetYourGuide), and Erik Muttersbach (Forto), among others. This infusion of capital underscores the potential Langdock sees in addressing the European market’s demand for compliant and secure integration of LLMs.

Langdock’s emphasis on regulatory compliance resonates with European companies seeking to integrate LLMs safely within their operations. By operating within a controlled environment, employees gain the flexibility to develop prompt libraries, leverage multiple LLMs, and handle sensitive documents securely. Beyond its chat interface, Langdock offers comprehensive solutions spanning security, cloud, and on-premises deployment options.

The company boasts a growing roster of clients, including industry leaders like Merck, GetYourGuide, HeyJobs, and Forto. Merck, in particular, has embraced Langdock’s interface, deploying it to its workforce of 63,000 employees. Walid Mehanna, chief data and AI officer at Merck, praises Langdock’s platform, noting its transformative impact on employee productivity and effectiveness.

While Langdock leads the charge in addressing vendor lock-in concerns, it faces competition from players like Dust, headquartered in Paris. Dust, backed by €5 million in funding from Sequoia, offers a similar interface aimed at harnessing LLMs for diverse applications such as customer service, research, and internal reporting. However, Langdock distinguishes itself by offering a broader scope of use cases and catering to various staff levels within organizations.

Langdock’s successful funding round underscores its pivotal role in reshaping how companies approach LLM adoption, providing a flexible solution that empowers businesses to harness the transformative potential of AI while mitigating risks associated with vendor lock-in.


Langdock’s successful funding round and emphasis on addressing vendor lock-in signify a growing demand for flexible solutions in the AI market. By empowering companies to select and integrate LLMs without being tied down to a single provider, Langdock is poised to reshape how businesses leverage AI technologies. The competition in this space underscores the significance of offering comprehensive solutions that cater to diverse use cases and regulatory requirements.
