Know what you are building before you write code

Short guides for founders writing a PRD, checking an idea, and planning the first version.

• How to write a PRD for a startup

  Write a startup PRD before you build: user, problem, scope, non-goals, success metrics, and the technical constraints a builder needs.

• What an AI PRD generator does

  An AI PRD generator turns a startup idea into a product requirements document and a build plan. Generate your first PRD free with FounderBrief.

• Validate a startup idea before building

  Validate a startup idea by writing the user, the current workaround, the first-month outcome, and a one-page PRD before you build.

• MVP planning checklist

  An MVP planning checklist: the user, the one job, the steps, the non-goals, the success signal, and the build order — before you code.

• Tech stack for a SaaS MVP

  Choose a SaaS MVP stack after the PRD: app framework, database and auth, storage, and payments — matched to the scope, not the other way around.
