An intent spike is a sudden, significant increase in buying signal activity from a prospect account over a short period (days to weeks). Where an account might normally show one or two intent signals per month, a spike shows five to ten signals concentrated in one week. Intent spikes are the most reliable predictor of imminent purchase, signaling that a buying committee has mobilized and is actively evaluating solutions. ABM teams that detect and act on intent spikes can intercept deals in the critical evaluation window.
An intent spike is a quantitative jump in intent activity. Baseline might be "no detected activity." A spike is "account researched our solution category 5 times, visited competitor sites, attended 3 related webinars, and had 2 job postings in relevant roles this week." The volume and velocity of signals matter more than any single signal. A spike indicates organizational alignment: multiple people at the company are suddenly focused on solving a problem.
Baseline intent tells you an account is "somewhat interested." A spike tells you they're "actively buying right now." A company with months of steady, low-level intent might not buy for 6-12 months. The same company with an intent spike has likely already decided to solve a problem and is now in evaluation mode. Buying window is 30-90 days. Spikes compress the sales cycle and dramatically improve deal probability.
Intent freshness measures age of signals. Intent spike measures concentration and velocity of signals. An old account might have one 90-day-old signal (low-freshness, low-spike). An account with five 2-day-old signals (high-freshness, high-spike) is more valuable. The ideal is recent, concentrated signals: high freshness + spike = highest conversion.
Use intent platforms that aggregate activity and flag anomalies. Bombora, ZoomInfo Intent, and 6sense all offer spike detection. Set baseline: what's normal activity for your category? Then flag accounts that exceed baseline by 2x, 3x, or 5x. Configure alerts: when an account shows spike, immediately alert the assigned AE and marketing team. Some teams use threshold rules: "flag if account has 5+ signals in 7 days."
Speed matters. When a spike is detected, reach out within 24-48 hours with a high-value, insight-led message: "I noticed your team is evaluating [solution category]. Here's something 3 similar companies in your space found valuable." Multi-thread immediately: reach out to multiple stakeholders if possible. Offer to expedite conversation: "I know you're in evaluation mode, so I'd be happy to run a 30-min briefing with you and your [function] leader." Spikes represent the highest-value sales activity. Prioritize them above everything except active opportunities.
Some spikes are obvious: concentrated research activity. Others are subtle: technology adoption + job posting + news mention. Some spikes predict short sales cycles (2-3 weeks of spike, 30-day close). Others indicate long evaluation cycles (4 weeks of spike, 90-day close). Learn your patterns by analyzing won deals: when did spikes occur relative to opportunity creation and close?
Not every spike converts. Sometimes a company shows spike for internal reasons (product evaluation for themselves, not for a new vendor). Filter noise by looking for multiple signal types: research + technographic + job posting is more credible than research alone. Layering intent signals improves accuracy.
Intent spikes are the most reliable predictor of imminent deals. Detect them, alert reps immediately, and reach out with insights to intercept accounts during active buying windows.
