What a credible process considers
These elements keep the analysis tied to live use.
- qualification rate
- appointment rate
- assignment alignment
- appointment win rate
- contract value
- cancellation rate
Create more revenue from demand already being generated.
Improve revenue per lead by separating qualification, appointment creation, assignment quality, sales conversion, and contract value.
Strategy guideUse your own evidence
Start with historical appointments, realistic eligibility rules, and outcomes that have had time to mature.
Your Opportunity
How can a company improve revenue per lead without buying more leads?
Revenue per lead can improve by raising the share of qualified leads that become appointments, assigning appointments to better-matched eligible reps, improving sales execution, and reducing leakage after the sale. Lithium Six focuses on the assignment decision.
What matters most
- qualification rate
- appointment rate
- assignment alignment
- appointment win rate
Build the analysis around the decision
The useful prediction is not merely whether an opportunity will close. The system must estimate how the expected outcome changes across the eligible representative choices, using only context available at assignment time.
The ranking becomes an operational policy only after eligibility, capacity, territory, and workflow requirements are applied.
Common analytical mistakes
These shortcuts can make model performance look better than it is.
- treating every lead as equally qualified
- measuring only cost per lead
- ignoring no-shows
- mixing sales and marketing attribution
- claiming all lift comes from assignment
How to evaluate the result
| Measurement | Why it matters | How to use it |
|---|---|---|
| Held-out log loss | Tests whether the method is accurate, stable, calibrated, and economically useful. | Compare appointments that have had enough time to reach an outcome |
| Brier score | Tests whether the method is accurate, stable, calibrated, and economically useful. | Compare similar periods, lead sources, and assignment approaches |
| Precision-recall performance | Tests whether the method is accurate, stable, calibrated, and economically useful. | Compare appointments assigned to recommended representatives |
| Recommendation alignment | Tests whether the method is accurate, stable, calibrated, and economically useful. | Review prediction accuracy alongside actual sales and revenue |
| Revenue per appointment | Tests whether the method is accurate, stable, calibrated, and economically useful. | Check for changes in lead mix and team performance before changing your approach |
From CRM history to a live, measurable decision
Connect your sales history
Isotope Labs organizes your appointments, representative assignments, and outcomes into a history we can evaluate, using information available before each assignment.
Test predictive accuracy
We test predictions against historical outcomes kept separate from model training to identify reliable matches between opportunities and sales representatives.
Backtest realistic assignments
We evaluate historical assignment scenarios that reflect representative eligibility, territories, availability, and workload limits.
Track adoption and sales results
See which recommendations your team uses and how those appointments perform, including close rate and revenue per appointment as outcomes become available.
Common questions
How can a company improve revenue per lead without buying more leads?
Revenue per lead can improve by raising the share of qualified leads that become appointments, assigning appointments to better-matched eligible reps, improving sales execution, and reducing leakage after the sale. Lithium Six focuses on the assignment decision.
What data should be used?
Use information known before assignment, a stable representative identifier, appointment date, and a mature won or lost outcome. Use reliable information that was available before the appointment was assigned.
How should performance be validated?
Use held-out data, compare against simple baselines, review ranking and probability metrics, and simulate the actual assignment constraints.
What should be monitored after launch?
Monitor recommendation coverage, alignment, mature win rate, revenue per appointment, calibration, agent capacity, and changes in source or opportunity mix.
