After
C+A tool that helps solo founders track their weekly experiments so they don't lose context 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 and tool details are specific but the actual user behavior segment remains fuzzy.
What pain are they paying for today?
Specific cost and time quantified, but Notion is a workaround, not direct competition.
Why now? What changed in the world?
Real tailwind identified, but Notion AI as proof point cuts both ways here.
What's the V1 you can build in 4 weeks?
This is a Google Form plus ChatGPT, not a defensible product worth building.
How will you reach the first 100 users?
Channels are concrete but volume and conversion math don't add up to 100.
What does success look like at month 6?
Concrete metrics, but the retention bar and revenue absence make the pre-seed bridge shaky.
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.
