Clear Channel Outdoor still rents rectangles beside roads and inside airports. But the more revealing business is the machinery behind them - audience data, automated buying and proof that a physical ad did something.
Reprompt builds AI agents for location data. Mapping companies like Foursquare, TomTom, and Radar use its agents to keep points-of-interest and business records current - verifying hours, status, ownership, and dozens of other attributes by cross-referencing web, social, government, and news sources. Founded in 2024 by ex-Mapbox and ex-Robinhood operators, the company turns work that once took weeks of manual research into runs that finish in under an hour.
VOYGR is a place-intelligence API that validates whether real-world businesses are actually operating and enriches their records with fresh web context - news, articles, hours, prices and events. Built by ex-Google Maps, Apple and Meta engineers, it is designed to give AI apps and agents map data they can trust, going beyond the 10-15 static attributes offered by traditional mapping APIs.

In 2025 it launched Synup OS (Agency OS), an operating system that adds CRM, sales pipeline, invoicing, and client-lifecycle tools so agencies can run their whole business - not just their clients' local presence - in a single platform.
Foursquare is a geospatial technology company that turns the physical world into structured, privacy-minded location data.

Onlife is a spatial-AI company that turns where people go into what they might do next. It began as the parent company behind Aglet, a location-based 'sneakerverse' game that had players walking real streets to collect virtual sneakers, then used the resulting movement data to build a Spatial Behavioral Engine and a consumer 'Smart Map' that fuses calendars, to-do lists and location into a self-organizing daily planner. Founded by former adidas trends director Ryan David Mullins, Onlife straddles the line between a playful consumer app and a serious geospatial-intelligence platform.
