I heard Marti Barletta speak twice today at the Marketing to Women conference in Chicago. Her first talk focused on her overall philosophy of marketing to women, and the second talk focused on "Prime Time Women." (The mature market)
Marti was, as expected, awesome. As can be read in her book, Marketing to Women or in her tompeters.com Cool Friend Interview, Marti has a keen grasp of both the market opportunity and the reasons most companies miss this opportunity. If you ever have a chance to hear her speak, don't miss it!
