How we built it

• React + Vite frontend, deployed instantly on Vercel
• Supabase for real-time group state and status sync
• Pre-scraped Web Summit Vancouver event data loaded client-side (no API dependency, works on flaky venue WiFi)
• Claude API for AI-powered group event recommendations based on member interests
• Built end-to-end in 3 hours at Web Summit Vancouver

Challenges we ran into

• Indoor location tracking is an unsolved problem — GPS doesn't work reliably inside large venues, so we designed around it with a manual zone-selection approach
• Keeping real-time group sync snappy on conference WiFi required caching static event data locally
• Scoping aggressively to ship a working demo in 3 hours

Accomplishments that we're proud of

• The overlap view — seeing which talks your group collectively wants to attend is immediately useful and didn't exist anywhere before
• Using real Web Summit Vancouver event data makes the demo feel like a product, not a prototype
• The AI group match feature surfaces talks none of your group would have found individually

What we learned

• The best conference tools are invisible — they reduce friction rather than add features
• Real-time sync is table stakes; the hard part is deciding what state actually needs to be shared
• A focused single-feature app demoes better than a broad one that half-works

What's next for Pack Coordinator

• Vision-based indoor positioning — point your camera at venue signage to auto-pin your location on the group map
• Integration with other major conference apps and event platforms
• Public launch
