Katie Hintz-Zambrano MOTHER Katie Hintz-Zambrano is the co-founder of Mother, a lifestyle site for modern moms. Immediately after having her first child, Katie noticed a gaping hole in the market for a full-service, style-centric parenting site, which lead to the birth of Mothermag.com in 2014. An S.F.-based journalist by way of NYC, her work has also appeared on Refinery29, Marie Claire, Vogue, Style.com, Elle, Nylon, i-D, New York Magazine, Details, and many others. In the fall of this year she will debut a smart + cool conference for mothers, based in the Bay Area.
