Found verbatim in 'The data' section, in the paragraph after the pilot results. Intercom's own words.

Our Agent is strict. It won’t approve large PRs. If a change is too big, too complex, or too broad in scope, it flags it and requires it to be broken down. Creating a direct, positive incentive for engineers to ship smaller, more incremental, well-scoped changes.

We started with a controlled pilot of over 100 PRs through the AI approval pipeline. The results: zero reverts of AI-approved PRs, and a 6–16x improvement in time-to-approval at the 75th percentile. Since then, the system has scaled significantly. In the first four weeks of broader rollout, 497 PRs went fully autonomous, with Claude writing the code and our AI approval system reviewing, approving, and shipping to production.

Last year, our CTO Darragh Curran set an explicit goal: double the productivity of our entire R&D organization within 12 months. Because the faster we can build and ship, the faster our customers get the capabilities they need. Nine months later, we did it. The results have been significant across the board, but the number that matters most for this post: downtime from breaking code changes dropped 35%, even as our deployments doubled.

Our PR review Agent doesn’t treat code review as a single task. It decomposes it into separate sub-jobs, each handled by an independent sub-Agent. One assesses the quality of the problem description. Another checks whether the diff actually aligns with the stated intent. Another reviews for safety concerns. Another checks for logical correctness. Another reviews against best practices and known anti-patterns.
