How Promptwatch is Powering the Best End-to-End AI Search Optimization Platform

Promptwatch, the analytics platform that helps brands understand and improve how they appear in AI-driven searches and conversations, led by Klaas Foppen and Gijs de Groot, has raised a €6 million seed round led by Seed + Speed Ventures after surpassing €2 million in ARR in May 2026, just 12 months after its launch, demonstrating a rapid and capital-efficient growth with only €1.2 million in pre-seed funding. The round also included participation from Blum Ventures, while Arches Capital doubled down on its pre-seed investment made in September 2025.

The New Era of Agentic AI Search.

AI Search Optimization (also known as GEO) has rapidly emerged as a critical marketing category as AI-driven search and buying behaviors evolve. Organizations must continuously adapt to remain visible across AI platforms where customers increasingly discover information and make decisions.

Promptwatch enables organizations to monitor and optimize their AI visibility through a proprietary dataset of 100,000,000+ daily AI interaction data points, including prompts, responses, citations, model updates, agent traffic, and content performance.

This foundation powers Promptwatch’s next generation of AI Search Optimization: Agentic AI Search Optimization, allowing organizations to connect their websites and automate AI visibility improvements through intelligent agents.

"In less than a year, Promptwatch has developed advanced AI Search Optimization capabilities, including Content Agent, Actions, and MCP, enabling organizations to connect directly with AI tools like ChatGPT and Claude. Agentic AI Search Optimization is the next step toward scaling AI Search strategies through automation."
