Promptwatch raises €6M as brands chase AI-search visibility

Promptwatch has raised a €6M seed round to build analytics for a problem that barely existed a few years ago: how brands appear inside AI-generated answers.

What happened

The Amsterdam-based company’s round was led by Seed + Speed Ventures, with participation from Blum Ventures and Arches Capital. Promptwatch tracks how companies, products and competitors are mentioned across AI services such as ChatGPT and Claude, then helps marketing teams identify where their visibility or positioning may be weak.

The startup says it reached €2M in annual recurring revenue within 12 months of launch. Its product sits in an emerging category often called generative-engine optimisation, or GEO. Unlike conventional search optimisation, the goal is not simply to rank a webpage. It is to understand which sources an AI system appears to trust, how it describes a brand and whether that description changes across prompts or models.

Why it matters

Consumer discovery is beginning to move from lists of links toward direct answers. That creates a measurement problem for companies: AI systems are less transparent than search engines, outputs can vary between users, and there is no single public ranking page to monitor.

Promptwatch’s early revenue suggests brands are already willing to pay for visibility data, even though the category is still developing. The harder question is whether these platforms can recommend actions that reliably change model outputs rather than only report them.

The bigger picture

A new marketing-software layer is forming around AI interfaces. Analytics, content strategy, reputation monitoring and product-data management may all need to adapt as chatbots become gateways to purchasing decisions.

The category could become large if AI discovery keeps growing, but it also faces platform risk. Model providers can change their sources, interfaces or policies quickly, so successful GEO companies will need to work across multiple systems and prove measurable commercial impact.
