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?
"Man" is a demographic filter, not a customer with a real, named problem.
What pain are they paying for today?
"No girl" is loneliness as a category, not a paid behavior you can point to.
Why now? What changed in the world?
"Many" isn't an answer — it's a shrug dressed up as a thesis.
What's the V1 you can build in 4 weeks?
"Sure" isn't a V1 — it's agreement with a question you didn't actually answer.
How will you reach the first 100 users?
"Gogo" is enthusiasm, not a distribution plan, and distribution is the whole game here.
What does success look like at month 6?
"Girl" is a punchline, not a metric, and we're six questions in with nothing real.
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.
