SalesRabbit, a CRM platform for industries like roofing and pest control, faced significant challenges with a legacy codebase and high defect rates after acquiring multiple companies, including RoofLink. To address these issues, they adopted CodeRabbit, an AI tool that significantly improved their code quality and deployment velocity. This tool enabled SalesRabbit to reduce defects by 30% and increase deployment speed by 25%, by providing a consistent coding standard across multiple languages and alleviating the review burden. CodeRabbit was particularly effective in identifying bugs that junior engineers missed, enhancing the reliability of the system and aligning team coding practices. The engineers' enthusiasm for CodeRabbit led to its rapid adoption, and it contributed to a happier and more productive engineering team. The tool's ability to standardize coding styles and reduce review times was key in improving the overall efficiency and effectiveness of SalesRabbit’s development process.
