I sat down with Brian Scanlan to explore what “AI-first” development actually looks like inside Intercom’s 15-year-old Rails monolith.

They’re generating over 95% of their code with Claude Code… and it’s not just engineers. Teams across the company are involved.

We got into how this is reshaping code review, who’s running production queries, and how they’re building guardrails to keep things from drifting. The part that stuck with me… knowing when to disengage the autopilot.
