Amsterdam-based LangWatch, a startup building the “world’s first” LLMops (Large Language Model Operations) platform to monitor, evaluate and optimise LLM-powered applications, has raised a €1 million pre-Seed round.
Passion Capital, a European pre-Seed VC firm, led the funding round, with support from Volta Ventures and Antler. The €1 million pre-Seed round will be used to continue the platforms’ development and attract engineering talent to the company to ensure the platform is ready for enterprise customers.
Manouk Draisma, Co-founder of LangWatch, comments, “Enterprises worldwide are looking for solutions that provide deep insights, ensure high-quality results, and clearly demonstrate impact to upper management. LangWatch sets a new standard for AI optimization—equipping engineers with powerful tools, including DSPy-based optimizers, to not only quickly identify and resolve issues but also continuously improve quality. By integrating these frameworks, LangWatch enables teams to iterate faster and more reliably than ever, allowing companies to deploy competitive AI solutions to production with greater speed and confidence.”
Founded in 2023 by Manouk Draisma and Rogério Chaves, LangWatch’s mission is to provide the most intuitive platform to assess the quality of LLM applications while enabling techies and non-techies to improve their LLM-performance.
The Founders bring first hand experience of building and scaling AI agent deployments, together combining more than 25 years of experience in the software serving at companies like Booking.com & Lightspeed.
With innovations like DSPy-based optimisers, LangWatch allows AI engineers to automatically identify the optimal prompts and models for their use-cases, reducing costs by revealing the efficient models and facilitating transitions to cheaper or open-source alternatives.
LangWatch’s UX/UI bridges the gap between technical and non-technical teams, featuring tools like the ‘Annotation Inbox’—a streamlined interface for feedback.
According to figures provided by Passion Capital, the 2024 global LLM market was valued at approximately €5.4 billion, with projections estimating it will reach between €117 billion and €133 billion by 2034, growing at a CAGR of 35-40%.
However scarcity of AI engineering talent and lack of trust in the predictability of outputs are barriers to LLM and AI Agent adoption within enterprises.
LangWatch has built a platform that allows AI engineers to quality control AI-powered applications, addressing one of the biggest challenges facing teams working with LLMs – ensuring consistent performance, efficiency and adaptability as new models emerge.
Will Orde, Partner at Passion Capital, comments, “LangWatch stands out because they’ve built a platform that makes AI quality control accessible to every engineer and non-technical domain-experts. Their hybrid approach—combining LLM prompt optimization with an intuitive, low-code framework—removes a major barrier to deploying reliable AI applications at scale. We were particularly impressed by the founding team’s unique blend of deep technical expertise and commercial acumen, which gives them a distinct advantage in bridging the gap between AI research/development and real-world enterprise adoption.”
