Your CRM is rotting. Not metaphorically. The data inside it is actively degrading every single day, and the rate is faster than most teams realize.
B2B contact data decays at approximately 30% per year. That number comes from multiple industry studies (Marketing Sherpa, Salesforce State of Sales, Gartner) and it holds up consistently. People change jobs every 2 to 3 years on average. That means roughly 35% to 45% of your contacts will change companies within any given 3-year window. When someone leaves a company, their work email stops working, their phone number changes, their job title is wrong, and the company data attached to their record may need updating.
But job changes are just one source of decay. Companies get acquired, merge, rebrand, or shut down. Departments restructure. People get promoted or switch roles internally. Office addresses change. Phone systems get replaced.
- After year 1: 15,000 records are stale (30%)
- After year 2: 25,500 records are stale (51%, because new decay adds to existing decay)
- After year 3: 34,300 records are stale (69%)
By year three, more than two-thirds of your CRM is unreliable. Your reps are calling wrong numbers, emailing bounced addresses, and making decisions based on outdated company information. Your lead scoring model is broken because it is scoring against stale titles and company sizes. Your reporting is inaccurate because it is segmenting by industries and company sizes that have changed.
The solution is continuous enrichment: filling in missing data and refreshing existing data on a regular schedule.
