Predictive Lead Scoring for B2B Sales: How Data Analytics Accelerates Conversions | Case Study

Learn how machine learning and survival analysis helped a B2B services firm predict which leads would close — and how fast — to prioritize sales efforts with confidence.

About the Client

A B2B professional services firm with a long sales cycle and a high-value consultative offering needed better visibility into which leads were likely to close — and how to close them faster.


The Challenge

The client’s CRM was full of data… but not insight.

They wanted to answer three big questions:

  1. Which contacts are most likely to convert?
  2. What behaviors predict success?
  3. How can we shorten the time it takes to close deals?

Their team was relying on gut instinct, ad hoc follow-up, and generalized engagement metrics — with no clear way to prioritize leads or refine strategy.


The Solution

We designed a custom analytics project combining:

  • Machine learning-based lead scoring (XGBoost model, 90.5% AUC)
  • Time-to-event (survival) analysis to model deal velocity
  • Ensemble modeling to identify hidden drivers of faster closes
  • CRM-ready scores, tiers, and confidence bands — prepared for seamless rollout

Each lead received a dynamic score and tier based on real-world conversion probability. We also uncovered the key behavioral signals that truly matter.

Key Findings

  • Lifecycle Stage was the strongest predictor of both conversion and speed to close.
  • Contact frequency (how often sales followed up) mattered more than job title.
  • Engagement scores helped qualification — but didn’t directly accelerate deals.
  • Lead scoring sharply separated lead quality:
    • 0% conversion in Low tier
    • 76.8% conversion in High tier
