Key Recommendations

1. Stay Laser-Focused on MVP:

Resist scope creep. The MVP must prove one thing: teams will connect their calendars to see meeting costs. Everything else is Phase 2+.

2. Leverage Low-Code Extensively:

Use Clerk, Supabase, Stripe, and Vercel to build in 4-6 weeks instead of 10-12. Every day saved = faster validation.

3. Build Waitlist Before MVP:

Start building landing page and waitlist Week 1. Target 300-500 signups before launch to ensure immediate user feedback.

4. Phase 2 Depends on Phase 1 Metrics:

Only proceed to Outlook integration and monetization if Phase 1 shows >40% weekly retention and user engagement.
