What's inside
1. VisionOne sentence — what does the product do, for whom, why now?
2. Target user (v1)First 100 users — who are they, what do they pay for, what value do they get?
3. Core workflowThe ONE workflow that creates value. Step-by-step.
4. The 5-question filterFor each feature: does it create value? Will first 100 users notice if missing? Can you fake it manually? Is there a free SaaS? Will it take more than 5 days?
5. In/out scopeCrisp lists. What's IN MVP, what's deferred to v2.
6. Success metricOne metric that decides MVP success. (e.g. 100 paying users in 90 days.)
7. Tech / infra notesStack assumptions, hosting, integrations.
8. Budget & timelineWhat you have. What you need.
