Winnie is a San Francisco-based childcare marketplace that connects millions of parents with licensed daycare centers, preschools, and early education providers across the United States. Founded in 2016 by Sara Mauskopf and Anne Halsall - two former Google and Postmates engineers who were also parents - Winnie has grown from a local San Francisco app into a national platform covering 200,000+ licensed providers in over 7,000 cities. The platform combines comprehensive data (tuition costs, licensing status, inspection reports, availability) with community reviews and a SaaS layer for providers called Winnie Pro. Ranked #177 on the 2023 Inc. 5000 list and #1 in Consumer Services, Winnie sits at the intersection of a 500-billion-dollar childcare crisis and a generation of parents who expect the same search experience for daycares that they get for restaurants.
