06: MVP Roadmap & Feature Prioritization

MVP Definition & Core Value Proposition

MVP: A web app that integrates with Google Calendar to automatically calculate and visualize the real-time cost of meetings for individuals and small teams.

Core Problem Solved: No visibility into meeting costs, leading to $400+ wasted per unnecessary hour-long meeting.

Must-Have Features (4 Core): Google Calendar integration, role-based cost calculation, personal dashboard, basic weekly cost report nudge.

What's NOT in MVP: Outlook/Zoom integrations, team hierarchies, advanced AI insights, enterprise SSO, mobile app.

User Success

  • Users see personalized meeting costs in <1 min after connect
  • Identify 20%+ wasteful meetings via dashboard
  • Receive weekly nudge email reducing meetings by 10%

Business Success

  • 100 users acquired in Month 1
  • 40% D30 retention
  • 15% free-to-paid conversion ($4/user/mo tier)

Validation Goals

Prove users connect calendars (80% rate), view dashboard weekly (3x/mo), and report 10%+ time savings.

Risk Management

🟡 Scope Creep: Lock MVP; parking lot ideas. Cont: Cut P2.
🔴 Tech Underest: 30% buffer; prototype Week 1. Cont: +2w timeline.
🟡 API Reliability: Cache Google API; fallbacks. Cont: Reduce deps.
🔴 Burnout: 1w buffers; outsource UI. Cont: Co-founder.
🔴 Low Adoption: Pre-build waitlist 500. Cont: Pivot to individuals.

Launch Strategy
