## AI overview

HubSpot describes a six-month evolution of its automated code review system. The system uses AI to review pull requests, provide feedback grounded in HubSpot-specific norms, and reduce the time engineers wait for feedback. The article says Sidekick reduced feedback time by 90%, with a peak reduction of 99.76% in September, and traces a shift from a Kubernetes-based system powered by Claude Code toward a framework native to HubSpot's Java stack.

## Source excerpt

As HubSpot engineers have increasingly started writing more and more of their code with both local and cloud coding agents, we've noticed that now more than ever, code review is taking up a large portion of cycle time on new changes.
