PHYSICAL.AI: The Agentic Ad Space Marketplace — Revolutionizing Real-World Advertisements

---

The Problem

Ad Spaces are everywhere, but finding and booking them is stuck in the 1990s.

• Discovery is broken — No centralized platform to find available ad spaces
• Pricing is opaque — Advertisers can't compare costs or value
• No data — Zero insight into traffic, impressions, or ROI
• High barriers — Small businesses can't access outdoor advertising

---

Our Solution

Physical.AI is the analytic platform for ad spaces — powered by real-time traffic data and AI.
