Nearly every Denver business would probably jump at an opportunity for ultra-cheap advertising and direct marketing opportunities aimed at eager consumers.

Now they can.

Enter Moxie-Moms, a Boulder-based company that connects businesses with mothers and mothers-to-be.

For a $50 annual fee, mothers get a 15 percent discount at participating businesses and are eligible to attend frequent fitness, entertainment or other recreational outings.

Businesses, meanwhile, receive free advertising on the Moxie-Mom website, www.moxie-moms.com , as well as opportunities to hold functions at their stores.

The group has gathered momentum in Boulder, Longmont and Broomfield since it debuted in November 2003, and within the past month and a half ventured to Denver.

All told, the group has 665 members and 81 business partners in 26 Colorado cities.

"It's going well," said Brooke White, owner of Get Fired Up, a pottery store with three Denver-area locations. White hosted a pottery-painting session last week with about a dozen moms, hoping the night of fun would spur future sales.

"I'm sure they will come back and bring their kids," White said.

Other businesses have already reaped the benefits of partnering with the group.

"It has brought me some new clients," said Dan Groenwald, owner of Boulder's Little Mountain Outdoor Gear For Kids. "It's been significant."
