Before
ai girlfriend
After
Cai girlfriend for a narrow first customer segment, packaged as a four-week V1 with one measurable pain, one acquisition channel, and a clear month-six success target.
Per-question score table
Who is this for, very specifically?
"Girlfriend" describes the product, not the customer — zero specificity about the user.
What pain are they paying for today?
This names a feeling, not a pain people are actively paying to solve.
Why now? What changed in the world?
No answer given; founder typed "dont" which signals zero conviction or thinking.
What's the V1 you can build in 4 weeks?
No answer provided — just keystrokes, no product scope, no plan.
How will you reach the first 100 users?
"df" is not an answer — there's no channel, no audience, no plan.
What does success look like at month 6?
No answer provided—just placeholder text with zero substance about goals or metrics.
Homework
Three concrete next steps before you run the next session.
- 1Interview 5 people in the exact customer segment and write down the words they use for the painful workflow.
- 2Build a clickable V1 outline that solves only the highest-friction step from those interviews.
- 3Send one concise outreach message to 20 likely first users and measure replies, not likes.
