This is exactly what we're building at Out Of Office. We've built a database of free and bookable spaces to work, meet, take calls, or take a break. We've collected all sorts of data you might find useful, like the number of seats, number of outlets, noise level, and other different amenities that we've rolled up into an 11-point score for each venue.

We've scouted thousands of coffee shops, hotel lobbies, parks, libraries, coworking, and other public spaces.

Right now we're only operating in San Francisco, but looking to expand to other cities in the future.
