The Error-Churn Correlation
Our research across 50 SaaS companies: every 1% increase in user-facing error rate correlates with 0.5-1% increase in monthly churn. For a company with $10M ARR and 5% monthly churn, reducing errors by 2% could save $100-200K/year in retained revenue.
High-impact quality investments: error budgets, user-facing error monitoring (not just server errors), performance budgets (every 100ms of latency = 2% conversion drop), and proactive customer communication during incidents.
