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.
Revnox applies exponential half-life decay. Each signal type has its own half-life based on how quickly the opportunity window closes.
| Signal type | Peak strength | Half-life |
|---|---|---|
| LinkedIn post (CEO) | 70 | 3 days |
| Funding round announced | 95 | 30 days |
| New VP Sales hired | 88 | 21 days |
| SDR job posting | 75 | 14 days |
| Tech stack change | 80 | 45 days |
| Product launch | 72 | 20 days |
| Competitor complaint | 65 | 7 days |
| C-suite departure | 78 | 30 days |
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 a correlation multiplier of 1.5-3x to the overall account score. Even if individual signals have decayed, correlations can still surface a company as high-priority.
You can adjust decay aggressiveness in Settings > Signal Preferences. "Fast decay" surfaces only the most recent signals. "Slow decay" keeps older signals visible longer, useful if your sales cycle is long.
