Dutch software startup LangWatch raises €1M pre-seed led by Passion Capital

Amesterdam-based startup LangWatch, which enhances LLM development through automated quality checks and optimization tools, has secured €1 million in pre-seed funding, led by Passion Capital, with additional backing from Volta Ventures and Antler.

  • Founded in 2023 by Manouk Draisma and Rogerio Chaves, LangWatch develops a platform designed to streamline and enhance the development of large language models (LLMs). 
  • The platform offers automated quality checks, continuous improvement tools, and an intuitive interface, enabling AI teams to test, evaluate, and optimize LLMs efficiently.
  • The startup integrates test-driven development practices to address issues of consistency, accuracy, and safety in generative AI, enabling organizations to deploy models more quickly, improve performance, and reduce costs.
  • According to LangWatch, their customers have been able to test, iterate, and ship approximately 10x faster by using the LangWatch platform.

Details of the deal

  • The pre-seed funding round was led by Passion Capital, a London-based venture capital firm that helps early-stage teams build outstanding digital media and technology companies. 
  • The round also saw participation from Volta Ventures, a Dutch VC supporting seed and early-stage internet and software startups in the Benelux region, as well as Antler, which recently closed its second Nordic fund, valued at approximately €100 million, aimed at supporting early-stage tech companies in Finland.
  • The startup will use the funds to expand its platform, improve AI deployment speed and reliability, and hire talent in areas like AI research, engineering, and GTM to drive growth.

"While this funding milestone is a major achievement, it’s just the beginning. LangWatch is dedicated to helping AI teams build world-class solutions for the toughest challenges. We’re expanding our platform across the evaluation stack and optimization studio to support faster, more reliable, and scalable AI deployments," claims Manouk Draisma, co-founder of LangWatch.
