Before
AI-powered legal document review for small law firms
After
C+AI-powered legal document review for small law firms 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?
Firm size and task are clear, but practice area and buyer remain ambiguous.
What pain are they paying for today?
Identifies real cost pressure but conflates firm and client pain points.
Why now? What changed in the world?
Cost curve is real but doesn't explain why small firms buy now.
What's the V1 you can build in 4 weeks?
Tight scope, single document type, clear output, and brutally achievable in four weeks.
How will you reach the first 100 users?
Generic content marketing plan with no targeting, timeline, or proof of channel fit.
What does success look like at month 6?
Vanity metrics with no segment specificity, retention proof, or honest funnel math.
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.
