About Us

Diffusion is an independent PR, social and content driven agency helping clients win the relentless battle for relevance. Our mission is to bring to life what brands do, and then to go one step further and demonstrate why they really matter. In the 21st Century, we believe that’s the real key to earning influence, changing behaviour, and driving real business value. Our campaign approach always has an absolute focus on measurable business results.

A highly-ambitious mid-sized agency, Diffusion has offices in London and New York, as well as an extensive global network of agency partners. We provide our clients with the hunger and agility of a boutique agency but with the ability to operate at scale and expand campaigns internationally through access to the powerful networks that usually come with an established agency.
