Case Study: EarnIn achieves governed AI code review at scale with CodeRabbit

EarnIn reviews 5,000+ pull requests with CodeRabbit and saves 12 weeks of reviewer effort

EarnIn, a provider of financial wellness products, faced a challenge as AI-assisted code creation increased the volume of pull requests across its hundreds of repositories. This surge required a consistent first-pass review process that would not divert senior reviewers from higher-order engineering concerns in their regulated financial services environment.

The company implemented CodeRabbit as a dedicated AI code review layer. The solution provided consistent first-pass coverage, governed by organization-wide standards and repository-specific configuration. As a result, CodeRabbit reviewed over 5,000 pull requests, achieved a 60% comment acceptance rate, and saved approximately 12 weeks of human reviewer effort over a 90-day period.
