WHAT IT IS
ABM inverts the conventional demand-gen funnel. Instead of casting a wide net for leads, ABM starts with a defined set of strategic accounts, maps the buying committee inside each, and orchestrates outreach, content, and advertising against those people by name. The ITSMA/Momentum framework codifies three tiers: 1:1 (bespoke per account), 1:few (clusters of similar accounts), and 1:many (hundreds of named accounts at scale).
HOW IT WORKS
Programs blend firmographic and intent signals (often via platforms like 6sense or Demandbase) with CRM data, then deliver tier-appropriate plays — executive outreach, industry campaigns, content hubs, or intent-triggered ad rotations. Measurement is pipeline- and revenue-based: target-account pipeline coverage, opportunity velocity, and win rate versus a non-target control.
WHEN TO USE
ABM fits when deal sizes are large, buying committees are complex, and sales cycles justify the orchestration cost. It underperforms when the ICP is broad, undifferentiated, or low-consideration.
