Hot Lead Detection

Quick Definition

Hot lead detection is a multi-signal scoring model that ranks prospects by likelihood of converting in the near term (typically 7 days). The model combines confidence-scored opens, click velocity, reply sentiment, document engagement, and prospect attributes (title, account tier, prior interaction) to produce a hot-lead score per prospect. Reps use the score to prioritise outreach.

The buying-window signal in B2B is short and noisy. Hot lead detection compresses dozens of low-confidence signals into one ranked list.

What the model uses

  • Confidence-scored open count. Multi-open Tier 1 within 48 hours of a key send is a strong positive signal.
  • Click velocity. Multiple clicks on pricing, calendar, or product pages within minutes outweighs a slow single click on a generic link.
  • Reply sentiment trajectory. A neutral-then-positive reply pattern outweighs a single positive reply.
  • Document engagement. Time on tracked PDFs or proposals weighted by page.
  • Prospect attributes. Title seniority, account ARR tier, prior engagement decay.

How to use it

The score is most useful as a daily triage layer. The top 10 to 15 percent of prospects by score should be worked first, with the rest queued by the cadence engine. A score that swings up sharply (cold to hot within a day) is the moment to call rather than email.

Frequently asked questions

Does Outsolvi expose the score?+

Is the score a black box?+

Not entirely. The contributing factors and their weights are visible per prospect. The underlying model parameters are not exposed; they are tuned on aggregate cohort data.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi runs Tier 1 to 5 confidence scoring on every open, native in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
