Superlocal CEO Alex Kehr on building an auto-logging location app and getting acquired by Foursquare
Jun 25, 2025 with Alex Kehr
Key Points
- Foursquare acquires Superlocal, an auto-logging location app that builds taste profiles from movement patterns, with CEO Alex Kehr staying on to grow the consumer product independently.
- Superlocal monetizes through place search affiliate deals with travel platforms like Expedia and subscription features driven by gamification, insulating it from AI inference cost pressures that plague higher-cadence products.
- A fog-of-war map feature revealing explored versus unexplored city areas, shipped before viral industry attention, emerged as an unexpected breakout built by an engineer over a weekend.
Summary
Alex Kehr, founder of Superlocal, has been acquired by Foursquare, with Kehr continuing to operate the consumer app independently post-deal. Kehr describes the outcome as a relief, noting the app is now being built without what he called "the constant fear of potentially always dying as a company."
Superlocal is a personalized mapping app that automatically logs visited locations without user input, builds a taste profile from movement patterns, and layers in manual check-in functionality reminiscent of original Foursquare. The app's AI-driven place search is designed to surface recommendations weighted against a user's established preferences.
On monetization, Kehr points to place search as a relatively clean revenue opportunity, citing affiliate-style arrangements with travel platforms like Expedia for hotel bookings. Subscription features have already shown traction, driven largely by gamification mechanics rather than AI features, which Kehr views as an incremental upside rather than a current driver.
AI inference costs are not a significant pressure on Superlocal's economics, because place search is an infrequent-use behavior, not a daily consumption loop. That structural difference insulates the app from the GPU cost dynamics pressuring higher-cadence AI products.
A fog-of-war map feature, which visually reveals explored versus unexplored areas of a city in the style of a video game, emerged as an unexpected breakout product built over a weekend by an engineer. Kehr notes Superlocal shipped it before a viral post on the concept drove broader industry attention to the idea.
Foursquare's core business remains B2B location data, and Kehr is explicit that he has limited visibility into that side of the operation. His mandate is consumer growth. He is relocating from Los Angeles to San Francisco.
