Every signal starts at a peak strength when first detected. Strength decays over time because buying intent is perishable, a company that raised money 6 months ago has already allocated that budget.
Each signal category decays in one of three ways. Exponential halves the strength every half-life. Linear falls in a straight line from the starting strength to 0 at the expiry age. Step holds the starting strength for the half-life, then drops to 30% of it. Every category is at 0 once it reaches its expiry age.
The signal types reference lists every category. Executive departures and layoffs decay too, but they are not buying signals: they are left out of the account's score, and recording one holds outreach to that company.
A funding round detected today starts at 95 strength. After 30 days it's at 47. After 60 days it's at 24, barely worth acting on.
This is why timing matters more than personalization. A mediocre email sent the day after a funding announcement will outperform a perfect email sent 6 weeks later.
When two or more signals align on the same company, Revnox applies the strongest matching pattern's multiplier, 1.6 to 3x by default, to the signal part of the account's score. Even if individual signals have decayed, correlations can still surface a company as high-priority.
Decay is the same for every workspace, and there is no setting for it. What admins and owners can change is how much each correlation pattern is worth to the workspace, under Settings > Signal weights.
