Graphite raises $52M and launches Diamond to reimagine code review for the age of AI

As of October 2025, Graphite has deprecated the Diamond name, integrating its AI code review functionalities under Graphite Agent, aiming to enhance the productivity of AI-native IDEs and autonomous development agents by incorporating AI in the review, testing, and deployment processes. Graphite's AI-powered code review platform provides developers with instant feedback on code changes, automatically summarizes pull requests, and offers actionable code suggestions, enabling a seamless code review experience akin to the workflows at Meta and Google. This platform is widely adopted by companies such as Shopify, Snowflake, and Figma, supporting fast-paced software teams. Graphite's recent $52 million Series B funding, led by Accel with contributions from Menlo Ventures, Shopify Ventures, and Figma Ventures, underscores its position as a leader in AI code review, with its standalone product, Diamond, offering customizable review features and universal GitHub integration, available for free for up to 100 pull requests per month. As AI continues to transform software development, Graphite is expanding its team, inviting talent to join its 30-person NYC-based team to further innovate in the field.
