Groupon founder Andrew Mason launches Detour, an iPhone app for location-aware walking tours in cities, starting with San Francisco
Groupon's ex-CEO launches audio tour app in San Francisco — Audio tours, often associated with museum field trips, are taking to the streets.
Context & Ripple Effects
Andrew Mason is making his first consumer bet since leaving Groupon, taking the audio tour out of the museum and onto the street with GPS-triggered narration in one city, San Francisco. The corpus shows where the arc lands: three years on, Detour is acquired by Bose as Mason shifts to Descript, his a16z-backed tool for editing audio via its text transcription.
First-order effects
- San Francisco walkers get a phone-native replacement for the rented headset tour, and Mason's startup now competes for tourist time directly against guided walks and museum-style audio rentals.
Second-order effects
- Big platforms validate the category rather than cede it: Google follows into trip guidance with Trips and later its Area 120 activity-booking app Touring Bird, while Headout raises $10M to book last-minute tours across cities — pushing Detour to differentiate on produced narrative quality.
Third-order effects
- Bose's acquisition signals the endpoint for niche audio-tour startups: content gets absorbed by hardware or platform owners, while founders like Mason migrate up the stack to the tools layer, editing audio through text rather than producing it city by city.
The trend: City audio tours are consolidating from independent apps into features of travel platforms and audio-hardware companies, with the durable value migrating to audio-editing tooling.
