LightGBM classifier · trained on 8,400 leads with 982 conversions · AUC 0.83 holdout · Brier 0.11 · isotonic calibration.
One classifier predicts the probability of closing within 30 days. A second regression predicts the customer's lifetime revenue, conditional on closing. Multiplied together, they yield expected revenue per lead — a single number with a heavy-tailed distribution. The top decile of leads is not ten percent more valuable than the median; it is roughly twenty times more valuable.
Probability that a lead converts within 30 days of form submission, given form responses, source, and session features.
Expected gross revenue from a customer over a 36-month horizon, conditional on conversion. Estimated from cohort retention curves and ticket history.
