Stage is a code review platform for engineering teams working with both human and AI-generated code. It reorganizes the review process by grouping changes into logical 'chapters' and ordering them for a natural reading flow, which the company says lets teams review and merge pull requests up to 5x faster than GitHub. Stage also ships an open-source CLI tool. The company is part of Y Combinator's Spring 2026 batch and was founded by two Stanford CS graduates.
