The Cozi family is getting bigger.
The Seattle company today announced that AOL and Working Mother will use its family calendar and communication platform, which should boost the site’s usage beyond its current 3 million members.
Cozi helped AOL’s MyDaily.com create the “MyDaily Family Organizer.” With Working Mother, it built a “Family Control Center” that connects to Cozi’s calendar, shopping list and journal applications.
The company also said it’s built a “Cozi Express” version of its service for Intel-based netbooks.
Cozi was started in 2005 by veterans of the Microsoft Money team.
