Amsterdam, the Netherlands, July 14, 2026 – Today, we're excited to announce that Promptwatch 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
Over the past year, AI Search Optimization (also known as GEO) has emerged as one of the fastest-growing categories in marketing. As AI-driven search and buying behavior continue to evolve, organizations need to adapt continuously to remain visible where customers are increasingly making decisions.
At Promptwatch, we help organizations stay ahead of these changes every day.
Our platform is powered by more than 100,000,000+ data points collected every day from real AI interactions, including prompts, responses, citations, model updates, agent traffic, and content performance. Rather than relying solely on back-end APIs, we provide organizations with the ability to understand and control what AI says about their brand.
This proprietary dataset is what powers the next generation of Promptwatch: Agentic AI Search Optimization.
Companies are now able to connect their website and have Promptwatch's Agents continuously optimize their AI Visibility so they no longer need to manage it themselves
"In less than a year, we've built some of the industry's most advanced AI Search Optimization features, including our Content Agent, Actions, and MCP (Model Context Protocol), allowing organizations to connect Promptwatch directly with AI tools like ChatGPT and Claude. Today, we're taking the next step with Agentic AI Search Optimization, making it easier for organizations to scale their AI Search strategy through automated execution." - Gijs de Groot, CEO/Co-founder at Promptwatch.
