Agent3

London, W1W 7RT, United Kingdom

ABM and ABX programs at 1:1, 1:few, and 1:many scale

Formed in London in 2013, Agent3 was an early pioneer of Account-Based Marketing and has since worked with clients including Adobe, Splunk, Expereo, OutSystems, NTT DATA, LinkedIn, and Salesforce. The agency is built around ABM and ABX programs designed to run at different scales, from highly targeted 1:1 engagements to broader 1:few and 1:many campaigns, backed by more than 125 client successes over the past decade.

Services span ABM strategy, lead scoring and qualification, pipeline and forecast analytics, campaign management, creative concepting and production, media planning and buying, brand strategy and positioning, and content strategy. A global team combines insights and strategy work with creative development, demand generation, and RevTech capability, and much of the work runs through JourneyLab, Agent3's proprietary platform that brings together technology, insight, and expertise to support account-based programs from planning through execution.

Proof points include helping Adobe power C-suite engagement through behavioral customer insight, building a gamified engagement experience for Splunk called Mission Possible, and helping Expereo exceed its demand generation targets. OutSystems worked with Agent3 to achieve internal global alignment on its ABM approach, while NTT DATA used the agency's ABM work to reshape its relationship with a major European bank. When in-person events were not possible, a Virtual Book Club program drove executive engagement and pipeline, and the agency has also delivered data-driven creative work for LinkedIn and an intent-driven demand generation program for Salesforce.
