Problem Statement
"Founders frequently spend tens of thousands of dollars developing complex AI models before verifying whether users actually need automated outputs or are willing to pay for them."
Section 3 Excerpt: Minimum Viable Model Scoping
Do not build custom model training pipelines for your v1.0 MVP. Utilize commercial APIs (OpenAI, Anthropic) or pre-trained open-weight models (Llama 3) connected via simple RAG.
Your primary objective during validation is measuring user retention and workflow accuracy requirements, not optimizing server-side latency or per-token infrastructure costs.
Validation Stage Milestones
| Stage | Primary Focus | Key Metric | Target Timeline |
|---|---|---|---|
| Concierge Trial | Manual Output Testing | User Acceptance Rate | Week 1-2 |
| Interactive MVP | API Core Workflow | Weekly Active Engagement | Week 3-6 |
| Scale & Optimize | Cost & Latency Reduction | Gross Margin % | Month 3+ |
