Is this the next feature worth building?
Bring a real question. We’ll scope the audience, evidence and study together.

The decision you face
From research to a decision
A build, revise or investigate decision
Keep the question, the evidence and the next action connected.
Ask
Would a guided setup solve a bigger customer problem than another dashboard?
Examine
Explore the task customers are trying to finish and compare the value of each direction. Keep uncertainty visible where the audience evidence is thin.
Act

A few useful answers
Before your first study.
Bring what you have and be clear about the gaps. Audience suitability depends on the evidence available; discuss the scope before relying on a study for a build decision.
You can start the conversation with a single feature, onboarding or positioning question. Book a call to agree the audience, study scope and pricing for your needs.
Sunzu creates audience characters grounded in customer evidence and enriched with a behavioural corpus. They are simulations. Use findings to explore directions and sharpen questions; lived experience, unexpected behaviour and consequential decisions still need research with real people.
