The one stop multi-layered destination to Reach the Unreached

OnionDev is a social marketing and technology company formed through a strategic partnership between Gram Vaani and the Life Impacting Services unit from OnMobile Global Ltd.

Our Mobile Vaani platform connects through measurable ways Corporates, Government Agencies, Non-Governmental Organizations, and Social Enterprises to consumers not touched by other media channels.

Gram Vaani does this by leveraging the latest mobile technology and its on-ground social marketing teams across various media dark and media-minimal areas. Our VAS partnerships with all major telecom operators gives us a unique edge to build Mobile Vaani into a marketplace for information services. Mobile Vaani has a presence is Bihar, Jharkhand, MP & Odisha with over 2 million users (and counting) as it continues to penetrate and scale across more states in the country.

How it works

Mobile Vani is driven by the twin engines of technology and human empathy. We believe that unless there is an understanding and grasp of the needs of a particular community, real change will remain elusive.

Top-down Vs. Bottom-up information models

Top-down information dissemination approaches which are typically followed are not empathetic to the specific needs of the beneficiary community. Information cannot be disseminated, it has to be contextualized.

The Mobile Vaani community powered media model does this through its three key pillars.

  1. First, our choice of the lowest common denominator technology of voice ensures that even poorly literate people are able to participate on Mobile Vaani
  2. Second, enabling people to create content for their communities and initiate discussions, ensures that the content is contextually relevant for them
  3. Third, our large offline network of community volunteers ensures that our users are trained and empowered, and take ownership of the platform to use it to transform their lives
