Before
AI code review for junior developers that works like a senior engineer
After
C+AI code review for junior developers that works like a senior engineer 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?
Demographic is clear but the buyer, company stage, and trigger remain undefined.
What pain are they paying for today?
This describes a problem, not a paid solution anyone currently buys today.
Why now? What changed in the world?
Three real tailwinds named but each is asserted, not proven with specific evidence.
What's the V1 you can build in 4 weeks?
Clear scope and surface, but missing the core differentiator versus existing AI review tools.
How will you reach the first 100 users?
Channels are plausible but lack specificity, ownership, and conversion math to be credible.
What does success look like at month 6?
Numbers are concrete but feel disconnected from a clear underlying go-to-market motion.
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.
