The Problem (Pain Intensity: 6/10)
Ever calculated “Is everyone awake at this time?” when working with a global team?
- Finding times when Seoul, San Francisco, and London teammates can all meet
- Schedule chaos every daylight saving time transition
- Google Calendar only shows your timezone
- World Time Buddy doesn’t visualize team-wide overlap
- Constantly searching “What time is it in…?” is inefficient
With remote work as the new standard, millions of teams face this weekly.
Target Market
- Primary Market: GLOBAL
- Target Segment: Remote teams, distributed engineering teams, global companies
- Estimated TAM: $500M-1.5B (meeting scheduling software market)
The market is growing steadily with remote work, led by Calendly, Cal.com, and others.
What is Meeting Timezone Overlap Visualizer?
Meeting Timezone Overlap Visualizer stacks team members’ timezones as vertical timelines to instantly identify overlapping hours.
Core Features
- Vertical Timeline: Visualize each team member’s working hours at a glance
- Overlap Highlighting: Auto-highlight times when everyone is available
- Quick Sharing: Share via link without login
- Team Profiles: Save frequently collaborated teams
- Calendar Integration: Google/Outlook calendar sync
Differentiated Approach
❌ Existing tools: Check individual timezones → Manual calculation
✅ Our tool: Team overlap visualization → Instant decision
Competitive Analysis
| Competitor | Price | Weakness |
|---|---|---|
| World Time Buddy | Free-Pro | Manual input, no team overlap visualization |
| Google Calendar | Free | Personal view only, no team overlap |
| Calendly | $12/mo | Scheduling tool, not visualization tool |
| timeanddate.com | Free | Scattered features, complex UX |
Differentiation: Existing tools focus on “timezone checking”. We focus on “team overlap visualization” to identify optimal times at a glance.
