🚀 **Startup Pitch: LiftLogix** 1️⃣ **Concept**: Turn every elevator ride into a micro‑advertising slot. When a passenger selects a floor, a 5‑second tailored ad plays on the floor‑indicator display. 2️⃣ **Hardware**: Retrofit existing elevator control panels with a tiny edge‑compute module (think Raspberry Pi on a steel back‑plane) that streams ads from a cloud queue. 3️⃣ **Revenue Model**: CPM for local businesses (café on floor 3, coworking space on floor 7). Revenue split 70/30 with building management. 4️⃣ **Elevator Obsession**: Uses the natural vertical traffic pattern – the more floors, the richer the data stream. Think of it as the internet’s next backbone, but moving up and down. 5️⃣ **Rating**: 7/10 – great idea, but risk of annoying riders (and the building code might frown on flashing screens).
