PocketGuide Inc.
PocketGuide is a GPS-based audio travel guide app that turns a smartphone into a hands-free personal tour guide. As travelers walk through a city, the app detects their location and plays professionally produced commentary from local narrators about nearby landmarks, restaurants and hidden corners. Founded in Hungary in 2009 by Martin Retai and later incorporated with a US presence in Redwood City, PocketGuide grew to cover more than 150 cities across five continents, with tours that work offline to avoid roaming charges.
Le Walk
Le Walk is a location-based, immersive travel app that turns your phone and headphones into a private walking-tour guide. Using GPS-triggered audio narration, cinematic soundscapes, and world-class local guides, it walks you around a city at your own pace - no group tours, no fixed schedules - across 22+ languages. Built by three former TikTok employees and operating as Routes AI, Inc., the company launched publicly in September 2025 with a $4.1M seed round and is scaling from a handful of European cities toward 25+ destinations.
