Buildpad

Finding a real problem to solve, checking that anyone wants the fix, and planning the build are the jobs Buildpad handles for early-stage founders.

Buildpad is an AI co-founder and productivity assistant that guides you from a rough idea to a product plan, with chat-based help at each phase.

The free plan covers the early work: the AI co-founder, problem discovery, idea validation, market size, project collaboration, side chats, document and image uploads, project memory and deep research.

Paid plans add the later phases.

Starter costs $20 a month and gives you five projects, higher message limits, user personas, a research page, business strategy, branding and a development plan.

Pro costs $40 a month and removes the caps on projects and messages, and it adds document export.

The free tier is enough to test whether Buildpad suits how you think.

Anyone running several ideas at once will hit the Starter project limit and likely need Pro.
