What's coming

THE OS FOR
THE idea stage.

Every feature answers the question every pre-seed founder is really asking: is this real, and am I the right person to build it?

01

Idea Validator

Feed in your idea. Get a structured assessment of market size, existing competition, and the core assumption to test first. A verdict, not a score.

ICP Canvas

Hypothesis builder for your ideal customer. Who they are, what they are already using, and why they would switch. Before you talk to a single person.

Problem Interview Generator

Custom discovery questions based on your specific idea and target customer. Built from the best interview frameworks, adapted for your context.

This is for you if

SOUND LIKE
you?

1

You have an idea you believe in but have not committed to it yet. You are still in the "is this real?" phase.

2

You have been building on nights and weekends but are not sure if you are solving a real problem or one you imagined.

3

You want to talk to customers but do not know what to ask. You are worried you will either lead them or waste their time.

4

You need to know if this is worth quitting your job for. You want data, not encouragement.
