How the Lab Works

From raw idea to hard data in three steps.

1. The Idea Roast

Input your raw problem and solution. Our AI Product Manager will brutally roast your concept to find the true Job-To-Be-Done.

2. Synthetic Personas

We instantly generate 5 distinct, highly-realistic AI personas from your target demographic, complete with budgets and biases.

3. Instant Interviews

Watch the platform interview your synthetic users concurrently to discover exact objections and output a beautiful PDF report.
