Section 06: MVP Roadmap & Feature Prioritization

MVP Definition & Core Value Proposition

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

Core Problem Solved: Lack of visibility into meeting costs leads to unproductive time waste, with users unable to quantify the $400+ expense of a single hour-long team meeting.

Must-Have Features:

  • Google Calendar integration for event parsing and attendee detection.
  • Basic cost calculation using role-based salary estimates.
  • Personal dashboard showing weekly meeting spend and trends.
  • Pre-meeting cost nudge in calendar events.
  • User authentication and basic permissions.

What's NOT in the MVP: Outlook/Zoom integrations, advanced team budgeting, AI-driven optimization insights, enterprise SSO, or custom salary imports—focus on individual validation first.

MVP Success Criteria:

  • User Success: Users see accurate cost breakdowns for 80% of their meetings and report 20% awareness increase via surveys.
  • Business Success: 100 beta users acquired in first month; 40% retention after 30 days; 15% conversion from free to $4/user/month Team plan.
  • Validation Goals: Test hypothesis that users value cost visibility (NPS > 30) and that nudges reduce meeting scheduling by 10%.
