| Chicago-based Groupon, the Web-based daily deal service, has inspired
dozens of clones. Now the number of Groupon-like websites has spurred
growth in an ancillary industry: deal aggregators.

Chicago-based Dealradar.com announced Tuesday that it has renamed and
overhauled its site, which was launched in February as Local Offer
Lounge. Dealradar covers daily deals from more than 80 websites in about
60 cities, including Chicago. According to Dealradar, some cities have
so many competing services that their residents would have to read at
least 15 e-mails every day to keep current on all the daily local
offers.

“As the daily deal market evolves, we’re seeing more new sites, product categories and business models,” Dealradar co-founder Jason Kalish said in a statement. “Whether well-funded or bootstrapped, each one has to get in front of consumers looking for great values and new experiences.  Dealradar.com provides a platform for all sites to do that.”

Dealradar competes with other services that collect daily deals from multiple websites and organizes them so consumers can search for offers that appeal to them. Yipit Perch and 8coupons, both based in New York, are also aggregators.
