Engagement Signal Half-Life

Engagement Signal Half-Life is the working assumption that any sales asset loses persuasive force on a predictable clock, and that enablement spend should be scheduled against that decay rather than against content production volume. Agencies typically bill for net-new assets while the deck, case study, or demo that actually closes deals quietly ages out of relevance. The framework asks one question per asset: how many days until a buyer's objection set changes enough that this piece stops answering it? That number sets the refresh interval. A digital sales room built in Arrows or a deal workspace in Dock is only as good as the content loaded into it, and stale rooms show measurable drop-off in buyer return visits. Pair the cadence with research automation like Aomni so account context refreshes alongside the assets. For retainers, this converts enablement from a one-time build into a recurring line item with a defensible trigger.
