Led by Rebekah Campbell, CEO, Posse provides a social search engine that allows users to find things to do and places to explore at a local level (bars, restaurants, gyms, shops, etc.) according to people within their social network and experts (celebrities, chefs, designers, musicians and politicians).
Posse also enables stores to grow by encouraging customers to spread the word. Zara, TopShop and Starbucks have joined the service, which is present in NYC and San Francisco.
