cubic

cubic is an AI-powered code review platform that automatically reviews pull requests, learns a team's codebase patterns, flags bugs and suggests fixes to help engineering teams merge code faster with fewer defects. It is pitched as a 'Cursor for code review' and integrates into existing developer workflows. Founded in early 2025 by Allis Yao and Paul Sanglé-Ferrière, the London company went through Y Combinator's X25 batch and launched publicly in April 2025, reaching the top spot on Product Hunt. The company reports helping teams merge pull requests meaningfully faster; funding beyond its YC backing has not been disclosed.
