My Penn classmate Lucinda Bronwyn Duncalfe, serial boss at Philadelphia tech start-ups (city-backed Real Foods, ClickEquation, Infonautics, Destiny WebSolutions), tells how West Conshohocken-based, FirstRound Capital-backed Monetate helps QVC, Best Buy, Dick's Sporting Goods, Best Western, National Geographic, Aeropostale and other online marketers target consumers -- for example, Famous Footwear uses Monetate "to show boots to those of us who live in the Northeast and other cold states and boat shoes to those who live in the South" -- in this easy interview on Fox News. 

Duncalfe notes that, after years of growth, desktop/laptop retail purchases flatlined this Christmas shopping season. Mobile visits to retail sites continue to rise, but many mobile shoppers are just looking, not buying, she adds.
