Diffusion PR

Diffusion PR is based at Brownlow House in High Holborn, London, with additional offices in New York and Los Angeles, and access to an international PR agency network for work outside those locations. The team, numbering between 11 and 50 people, works with innovators and high-growth organisations across sectors including Science & Innovation, Climate & Cleantech, Purpose, Technology, Consumer & Lifestyle, and B2B Technology & Corporate. Clients referenced in its project examples include pharma intelligence, mapping, AI mental health, data centre heat, sustainable aviation fuel, and InsurTech businesses, indicating a focus on organisations introducing new technology, science-based products, or business models to the market. The agency's declared services span search engine optimization, branding, public relations, and social media marketing, delivered under an approach it describes as helping clients overcome strategic hurdles such as low awareness, lack of trust, or outdated brand perception before focusing on growth activities like winning new clients, securing funding, entering new markets, or attracting talent. It describes starting engagements by developing a clear narrative explaining a client's purpose, then building communications, brand, and marketing programmes around that story to support commercial outcomes. The agency also publishes research and reports, such as work on communicating trust in science, as part of its output for clients in its core sectors.
