Decima2, a marketing startup, has raised £480,000 in a pre-seed round from Haatch, Y Combinator and Partner Nicolas Dessaigne. The funding includes £335,000 in equity investment and £125,000 in equity-free grant support, and was completed in December 2025. It will be used to further develop Decima2’s product and expand its AI optimisation capabilities.
Founders Alexix Monks and Torty Sivill met while studying computer science at the University of Bristol. Sivill holds a PhD in artificial intelligence from the Alan Turing Institute, and Decima2’s technology has received recognition from the Bristol Innovation Awards, Oxbridge AI Challenge, Technology for Marketing Awards, Women TechEU, and Tech Nation Rising Stars.
The platform is designed to eliminate wasted marketing spend for small and medium-sized businesses by helping them understand what genuinely drives growth across paid marketing channels. It uses causal modelling and generative AI to continually optimise Google Ads and high-converting landing pages, giving smaller teams access to analytical capabilities traditionally reserved for large enterprises.
