ZipDial

ZipDial was a Bangalore, India based mobile marketing and analytics startup founded in 2010 that pioneered "missed call" engagement, letting consumers interact with brands and campaigns by giving a toll-free number a missed call rather than paying for a call or SMS. It was acquired by Twitter in January 2015 and its standalone product was subsequently wound down. The company was backed by 500 Global (formerly 500 Startups) among other investors. As of this enrichment pass the original company is defunct and no longer operates a developer program or public API; the zipdial.com domain now resolves to an unrelated general-interest content/news aggregation site with no developer, documentation, or API surface. This profile is retained as a historical portfolio-company record.

ZipDial is profiled on the APIs.io network. Tagged areas include Company, Missed Call, Mobile Marketing, Mobile Engagement, and Analytics.
