HubSpot Deploys Sidekick To Accelerate Code Reviews
8.2
HubSpot’s Developer Experience AI team rolled out Sidekick, an LLM-driven code reviewer, across every pull request over the past six months, cutting engineer feedback latency by about 90% and peaking at a 99.76% reduction in September. They migrated from a Kubernetes/Claude-based Crucible to Aviator, an internal Java agent framework, and added a Judge Agent evaluator to filter noise and improve review quality.
