I write about what leading a product means now that coding agents do the building: deciding what deserves to exist, who gets to decide it, and how a team carries those decisions all the way into what ships.

Grew IBM’s Watson Assistant past $75 million in four years, then took a Procore product past $10 million in nine months.

  • A card headed What and why, with four people beside it, above a dark panel headed How, with one person and plan mode on. An arrow runs from what and why down to how.

    Claude Code plan mode isn’t a full plan

    Plan mode in your coding agent plans how to build, not what you’re building or why. Don’t wing it in Claude Code or Cursor. Plan the what and the why first.

  • A feature PRD beside three project plans. Each project listed in the PRD leads to its own plan, made of outcomes, rules and UI.

    A PRD template for coding agents

    The typical PRD was written for a team that talks. For coding agents, keep it for the whole feature, then break it into small projects. PRD template included.

  • A feature in Grove holding a finished prototype, with two projects planned beside it.

    Prototypes are for learning, not for building

    We stopped writing specs and let prototypes define features. Bad idea. Here’s what broke, and the method we use instead.

  • An outline of strategy, its features and their projects, each marked with its owner. The founder or head of product owns the strategy and one feature. A product lead owns the other feature, and a product lead owns each project.

    The bottleneck isn’t the PM, it’s who gets to decide

    Coding agents moved the bottleneck from building to deciding. More product managers won’t clear it. Being clear about who decides what will.

  • The Grove mark above the line “Great ideas deserve to flourish” on a deep green gradient.

    Why we started Grove

    Coding agents made building fast. Deciding what to build, and checking it came out right, didn’t get faster. That’s why we started Grove.
