About Decima
Company Overview: Decima puts enterprise-grade marketing intelligence directly into the hands of Small and Medium-Sized Enterprises (SMEs). Across the globe, SMEs spend hundreds of billions on digital advertising every year, yet the vast majority lack a reliable way to know which campaigns are actually driving business growth and which are wasting valuable budget. This level of sophisticated marketing analytics has historically been reserved for large corporations with dedicated in-house data teams or deep-pocketed agency partnerships. Decima closes this gap entirely.
The Problem We Solve: Most SMEs spending between £2k and £50k per month on digital channels like Meta and Google know their advertising is underperforming, but they lack the tools and specialised data expertise to fix it. Traditional marketing agencies are expensive, slow, and heavily reliant on surface-level metrics (clicks, impressions, CPC) that obscure the real truth about business growth. Meanwhile, traditional analytics tools require technical literacy that time-strapped founders don't possess, and standard AI tools operate as opaque "black boxes" that demand blind trust.
Our Solution & The Explainable AI Difference: Built on rigorous PhD research from the Alan Turing Institute (the UK's national institute for data science and AI) alongside Oxford Saïd MBA-level commercial experience, Decima is categorically different. We use Explainable AI to automatically identify which campaigns work, scale up the ones that do, and immediately cut the ones that don't. Unlike black-box tools that silently reallocate budgets based on hidden algorithms, Decima translates complex analytics into transparent, actionable strategic insights. Our platform operates quietly in the background as an intuitive, transparent marketing partner, giving SMEs enterprise-grade intelligence without the data overhead or operational pull.
