You're targeting companies based on demographics, not buying behavior. Without knowing which tech they use, who they've churned from, and what their purchase patterns look like, your ABM lists are full of poor-fit accounts.
Campaigns fire based on page visits or ebook downloads, not real signs of intent like competitive evaluation, vendor renewals, or tech stack churn.
Even when companies are evaluating, you're often competing against sticky incumbents with long contract terms. Without knowing which competitive scenarios you typically win, you waste budget on deals you'll lose.
Identify companies actively trialing competitors, recently churned from incumbents, or approaching renewal windows. Launch campaigns when they're in active evaluation mode, not months before or after they're ready to buy.
Filter by ICP fit (based on tech stack and competitive overlap), purchase intent (trials, churn, renewals), and win probability (based on which competitive scenarios you historically win). Focus budget on opportunities with the highest conversion odds.
See when companies start trialing your competitors, often before the competitor's sales team even knows. Engage early with messaging tailored to their current vendor and evaluation context
MarketSizer shows which competitive scenarios you've historically won. Build ABM lists targeting companies in similar situations, using the same incumbent, same tech stack patterns, same evaluation behavior, so you replicate success instead of guessing.
