## The 'Negative Churn' God Mode
Most businesses have a leaky bucket—customers leave, and they have to spend marketing dollars to replace them. Elite Enterprise SaaS companies have a bucket that mathematically overflows on its own. They sell 10 software seats to a client, wait 6 months, and upsell them 500 more seats.
### FAQ
**Q: Why do VCs care so much about NRR?**
A: Net Revenue Retention is the single most important metric for software valuation. If a company has 125% NRR, it means the SaaS product is so "Sticky" that they could theoretically fire their entire external Sales & Marketing department, acquire precisely ZERO new logos this year, and their company revenue would still grow by 25% purely from existing customers upgrading their plans.
