Deel.io is an aggregator of coupon-based offers available on daily deals websites around the globe. It organizes and presents them overlapped on a geographical layer. In this way, users can discover the best deals around their current location from a central place.
The site offers integration with other services, such as Yelp (from which it imports ratings and reviews) and Facebook (for facilitating easy deal-sharing with friends).
The service originated initially in Seattle and expanded gradually to the entire US. Currently they are adding additional cities in the United States but they don’t track non-US deals.
Deelio has some serious search expertise behind it, being founded by Sanjay Mavinkurve and Vijay Boyapati, both former Google engineers. The company was founded in July 2011, is headquartered in Seattle, United States and towards the end of 2011 it had 4 employees.
