PromptWatch

Promptwatch is an Amsterdam-based Generative Engine Optimisation platform that solves the growing visibility gap caused by the shift from traditional search engines to conversational artificial intelligence. Founded in 2025 by Gijs de Groot and Klaas Foppen, the platform aims to empower digital marketers to secure and maintain prominence within generated responses. As users increasingly bypass Google for platforms like ChatGPT and Perplexity, Promptwatch’s core mission is providing the critical infrastructure required to track, analyse, and optimise brand presence. The company operates from its Dutch headquarters with a clear vision to become the definitive industry standard for global visibility data management.

Promptwatch has rapidly established significant trust within the Generative Engine Optimisation market, demonstrating strong Experience, Expertise, Authoritativeness, and Trustworthiness. The company supports a diverse range of sectors, including higher education, finance, marketing, and recruitment. Notable clients such as Erasmus University, Independer, Monks, and Brunel utilise the platform to ensure their brands remain prominent in an evolving search landscape. This enterprise level adoption validates the platform’s data accuracy and strategic utility for large-scale marketing operations. Promptwatch currently monitors visibility for over five thousand seven hundred brands globally. To accelerate product development and expand its capabilities, the company successfully secured a critical one million, two hundred thousand Euro seed funding round led by Arches Capital. By providing highly transparent, citation level data and actionable intelligence, Promptwatch equips forward thinking marketing agencies and corporate teams with the verifiable insights required to dominate the next generation of artificial intelligence driven search and discovery ecosystems.

Promptwatch distinguishes itself from alternative visibility trackers through its unparalleled data depth and model coverage. While competitors often restrict specific language models to premium tiers, Promptwatch tracks over nine major artificial intelligence systems, including ChatGPT, Gemini, and Perplexity, across all subscription levels. Its standout competitive advantage lies in its proprietary crawler log analysis, which directly monitors how bots interact with a target website. Furthermore, the platform offers advanced geographic tracking down to the city level, alongside granular source tracking that identifies brand citations across Reddit threads and YouTube videos, delivering a completely comprehensive view of Answer Engine Optimisation marketing performance.
