Cosmos Brands is a UK-registered performance marketing agency based in London. We work exclusively with e-commerce brands and consumer businesses that want to move fast, scale hard, and outperform their competition through paid social, Shopify optimisation, and conversion-focused funnels.
We don't do retainer work that looks busy but moves slowly. We take ownership of execution, report on real numbers, and scale what works. Every client gets the same level of attention — we keep our roster focused on purpose.
If you're building something real and need a team that gets it done — we should talk.
