Wire the signal to the moment, not the quarter
A perfect signal that arrives three weeks late is a worse asset than a rough one that arrives the same day. The strongest expansion conversations happen within hours or days of the triggering moment, because the closer the outreach is to the moment of adoption, the more natural it feels (Lusha). When you reach out the afternoon a customer's tenth seat went active, you are responding to something they just lived; reach out six weeks later and you are reciting a stale data point they have forgotten. This is why the latency from detection to outreach is a metric you track as carefully as the conversion itself, and why compressing it is what drops time-to-expansion from 145 days to 67 (Saber).
The architecture that wins is push, not pull. A signal that crosses its threshold should fire an event the same hour, into the surface where the owning human already works, a Slack channel, the CRM record, the account manager's task queue, whatever they look at daily. Do not make anyone remember to open a dashboard and scan a list; the dashboard is where signals go to be ignored. Decide up front who the signal routes to and on what surface, then make the routing automatic.
A 95-percent seat alert on a named account should land as a task on that account's owner with the context attached: which seats, how long saturated, what the next tier costs. The human's job is to judge the relationship and have the conversation, not to discover the signal exists. Build the plumbing once and every future signal rides the same rails. For running this end to end without a dedicated team, see run customer success without a CS team, and for handing the detection itself to automation, upsell and cross-sell triggers run by AI agents.
