Develop your idea.
Define the strategy and tools to build it.

Pinnlo helps founders develop ideas into structured product strategies through text or voice. It defines the problem, audience, scope and first release, alongside an AI toolbox for research and planning. Strategies can then be published as opportunities for delivery partners.

The problem

Turning an early idea into a practical product brief.

Founders need to define their audience, priorities and first release before they can commission development. Pinnlo guides that process through conversation and organises the results into a strategy they can review and share.

ConstraintKeep generated strategies grounded in the founder’s input and use automated evaluations to check the quality of the output.
What we built

Guided planning and an AI toolbox.

The conversation

A text or voice conversation guides the founder through the questions needed to define their product. Separate agent activities handle each stage of the discussion.

The strategy

The conversation becomes a structured strategy covering the problem, audience, scope, first release and success criteria. Each section links back to the input that informed it.
