What Definition Agency does

Definition Agency is a Leeds-based B2B communications agency that delivers an integrated portfolio of public relations, SEO, AI visibility, social media, content marketing, internal communications, and public affairs services. Founded in 2002 and operating as a privately held company with 11-50 employees, the firm positions itself as a specialist rather than generalist, serving enterprise clients across technology (including fintech, edtech, cleantech, healthtech, proptech, and SaaS), industrial (engineering, energy, maritime, logistics, transport, science), professional services (legal, accounting), and third sector (charity, education, healthcare) verticals. Named clients include Amazon, Xero, Honda, BNP Paribas, British Land, Bullhorn, Checkout.com, Soldo, and Innovate Finance, indicating enterprise-grade relationships across diverse sectors.

The agency's core technology proposition is the integration of traditionally separate communications disciplines — PR and media relations, SEO, AI visibility, social media (notably LinkedIn), and content marketing — into a unified digital-first service offering. It does not own a proprietary SaaS platform; rather, integrated service delivery is the differentiator, supported by a team that includes former national print and broadcast journalists and big-brand communications leaders. The agency has accumulated close to 100 national and international awards and is ranked among PRWeek's top 10 UK B2B PR agencies for 2026.

Definition generates revenue through professional services engagements with B2B enterprise and mid-market clients, using a sales-led go-to-market motion with direct client relationships and case study marketing. The firm executed an active rollup strategy, acquiring Words&Pictures (November 2020), Redhouse (November 2020), and TopLine Comms including TopLine Film (June 2021), expanding sector breadth and creative content capabilities. Pricing is quote-based and not publicly disclosed, consistent with bespoke B2B professional services. The firm remains privately owned with no disclosed parent company or external institutional investors.
