Sosh
Sosh was a San Francisco-based social-discovery mobile app (founded 2010) that acted as a "social concierge," giving members a personalized collection of local activities, events, and places to do and share. It was backed by Battery Ventures and Khosla Ventures among others. Sosh was acqui-hired by on-demand delivery service Postmates in November 2015 and the consumer app was subsequently discontinued. Enrichment research (WebFetch) found no surviving product, developer portal, documentation, or public API; the sosh.com domain is now a parked "for sale" listing. There is no live API surface to enrich, so no API artifacts were produced.
Sosh is profiled on the APIs.io network. Tagged areas include Company, Defunct, Social Discovery, Local Activities, and Consumer Mobile App.
