London-based geoSurge has raised an oversubscribed $12 million seed round led by AlbionVC, with participation from Play Ventures, Octopus Ventures, Celero Ventures, Boost Capital, existing investors Passion Capital and Tuesday Capital, as well as angel investors from Google DeepMind, Microsoft AI and Signal AI.

Founded to help brands assess and improve how they are represented within large language models, geoSurge is positioning itself around a growing concern for companies as AI-generated answers play a larger role in search, discovery and purchasing decisions.

The company said the new funding will be used to expand its research and engineering teams, invest in AI infrastructure and compute capacity, and accelerate development of its Corpus Engineering discipline and wider AI visibility capabilities.

The round highlights investor interest in startups building tools for the emerging layer between brands and AI systems, as businesses look for ways to understand how they appear inside platforms such as ChatGPT, Gemini and Claude.
