In the fast-paced world of software development, Cubic stands out as an AI-powered code review platform that simplifies pull request workflows and boosts engineering productivity. Founded in early 2025 by Allis Yao and Paul Sanglé-Ferrière, Cubic is based in London and supported by Y Combinator’s Spring 2025 batch. The startup helps teams merge pull requests up to 40% faster while improving code quality across the board.
From Concept to Launch: A Data-Driven Debut
Cubic launched publicly on Product Hunt on April 28, 2025, earning the #1 spot for both the day and the week. Its flagship innovation, called “Cursor for code review,” uses machine learning to analyze coding patterns and deliver automated feedback on pull requests. In its first month, Cubic processed thousands of PRs. The platform’s AI suggested precise fixes that cut manual review time by an average of 40%. That number alone shows just how much time engineering teams can save.
The startup received early support from Y Combinator and backing from Nicolas Dessaigne, a notable partner and investor. From a lean founding team of two, Cubic has grown to about ten people. Engineers like Lorenzo B. and Bohdan Agarkov joined early, supporting the company’s drive for rapid development.
Intelligent Workflows for Modern Development Teams
Cubic’s strength lies in its visual workflow interface. It doesn’t just present code changes—it adds context and suggestions, helping developers review faster. The system learns from your project’s coding style and conventions. As a result, the feedback it gives is tailored, relevant, and consistent with your team’s standards.
Teams using Cubic are already seeing results. For instance, cal.com reduced post-merge bugs by 35%. Meanwhile, n8n reported saving two days per sprint. Even The Linux Foundation has added Cubic to its CI/CD pipelines, showing the tool’s ability to scale for large projects.
Competitive Edge: Why Cubic Stands Out
Cubic excels in three core areas: adaptive learning, integration, and ease of use. It learns from your repository’s history and applies that knowledge to future reviews. It fits seamlessly into existing Git workflows. And the platform’s interface presents changes step-by-step, making complex reviews easier to navigate.
This clear value proposition sets Cubic apart in the crowded developer tools market. It doesn’t just automate reviews; it improves them.
Looking Ahead: Growth and Market Adoption
Since its Y Combinator debut, Cubic has grown its user base to include startups and established teams alike. With headquarters in London, the company is reaching out to a global market of developers seeking speed and precision in their code reviews. A generous launch offer—two weeks free and 30% off for two months with code “YCLAUNCH”—has already driven a 50% rise in trial sign-ups.
So far, Cubic has not announced funding beyond its pre-seed Y Combinator backing. Still, with growing revenue from subscriptions and increasing adoption, the company appears financially steady. Its data-first strategy and seamless UX have struck a chord with modern developers.
Final Thoughts
Cubic isn’t just another code review tool. It’s part of a broader shift toward smart automation in software development. By studying codebase patterns and delivering visual, context-rich insights, Cubic enables teams to ship better code, faster. With 40% quicker PR merges and reduced bug rates, its approach is already making waves among teams like cal.com, n8n, and The Linux Foundation. As more teams look for AI-powered efficiency, Cubic is well-positioned to lead.
