PullRequest

The firm's core business revolves around providing on-demand access to a network of vetted, senior-level developers who perform code reviews. This service integrates directly into clients' existing development workflows and tools such as GitHub, BitBucket, and Slack. PullRequest's business model combines artificial intelligence with human expertise. The platform's AI-driven tools perform initial automated checks for bugs, security vulnerabilities, and performance issues, after which a human reviewer provides in-depth feedback. This hybrid approach is intended to reduce the time in-house developers spend on code reviews, thereby accelerating the development lifecycle and lowering costs. Revenue is generated based on usage, with pricing per review credit under an annual contract.

Significant milestones for PullRequest include its participation in the Y Combinator accelerator program in the summer of 2017 and securing $10.4 million in funding over three rounds. A notable Series A round in April 2018, led by Google's Gradient Ventures, raised $8 million. In February 2020, PullRequest acquired Moonlight, a marketplace for remote software developers, to expand its network and capabilities toward automatically fixing identified code issues. Subsequently, in April 2022, HackerOne, a leader in human-powered security, acquired PullRequest to integrate its developer-first security testing solutions and expand its service offerings. Following the acquisition, the service was rebranded as HackerOne Code, continuing to serve thousands of organizations by embedding expert security reviewers into their software development lifecycles.
