Find CRM Contacts Who Switched Jobs
Detect which contacts in your CRM changed companies, find their new work emails, and add them to re-engagement campaigns. Past champions win at 37% vs 19% for cold outbound — nearly 2x the win rate (Champify, 230K champions analyzed).When to use
- Quarterly CRM hygiene — catch contacts who left their companies
- Win-back campaigns — re-engage churned contacts at their new companies
- Pipeline reactivation — find champions who moved to new accounts
How to run it
Uses the job-change-detector skill. Connect your CRM via MCP (HubSpot, Salesforce), then type in Claude Code:CLI commands (advanced)

Key rules
- Pilot first. Always test on 2 rows before running 1000+ contacts.
- LinkedIn URLs improve accuracy. If your CRM has them, use
crustdata_person_enrichmentwith LinkedIn URL for best results. - Data freshness. PDL/Crustdata data can be 1-3 months stale — cross-reference with LinkedIn for high-value contacts.
- Batch size. For large lists (1000+), process in batches of 200-500.
Why this matters
- 30% of B2B contacts switch jobs every year (Cognism)
- At 2.1% monthly data decay, a 10K-contact CRM loses ~210 valid emails per month (SMARTe)
- Past champions convert at 3x the rate of cold prospects (UserGems)
- The first seller to contact after a trigger event is 5x more likely to win (Autobound)
Common pitfalls
| Pitfall | Fix |
|---|---|
| Company name mismatch due to casing (“Ramp” vs “RAMP”) | Normalize to lowercase before comparing |
| False positives from acquisitions/rebrands | Check if domain also changed, not just company name |
| Missing LinkedIn URLs reduces accuracy | Enrich LinkedIn URLs first if not in CRM |
