Merrill Lutsky (Co-founder & CEO of Graphite) joins Jay to discuss how AI code generation is breaking traditional development workflows and why code review has become the real bottleneck.

Merrill brings 12 years of engineering experience from Square, Oscar Health, and YC-backed startups, plus insights from building Graphite into the leading code review platform for AI-generated code.

The conversation explores how stacked pull requests - originally designed for thousand-engineer teams at Meta and Google - are now essential for every startup using AI agents that can generate code at unprecedented scale. Graphite combines deterministic workflows (merge queues, reviewer assignment) with their AI review agent "Diamond" that reviews every code change in seconds, handling the 10x increase in code volume from tools like Claude Code and Cursor.

Tune into the full episode to learn how stacked PRs can 10x your AI development workflow and why code review is becoming more important than code generation!
