"The vision behind Gram Vaani is to build technologies that empower people at the bottom of the pyramid," co-founder Aaditeshwar Seth, a computer scientist-turned-entrepreneur, said in aninterview. "People who currently do not have a voice, whose stories don't get told or profiled in mainstream media, they should actually be able to bring out their problems, their issues, their demands."

Mobile Vaani's simple, low-cost system allows users to post and receive social-media messages using voice, on basic mobile phones, allowing them to bypass the Internet. More than 90 percent of India's 833 millionrural populationlack access to the Internet andas many as 450 millionare illiterate. Mobile Vaani estimates that roughly 65 percent of the poorly-literate/low-income population in India is unlikely to have access to the internet in the next decade, but 40 percent of those already have access to mobile phones.

The widow of the deceased migrant worker is a case in point. Unsure of the whereabouts of her husband who had migrated to Delhi for work, she placed a call to the Mobile Vaani network and told her story. A person in Delhi reached out to her via Mobile Vaani to inform her of the details of her husband's death. The story, published on Mobile Vaani's network, reached the director of the state's Department of Labor, who prompted his government to pay the young widow the compensation she was due.

The idea for the firm was sparked in 2008 when Dr. Seth won a Knight Foundation competition for software that first-time users of community radio could easily operate. Gram Vaani received a $200,000 grant to prototype its solution.

In 2013 Gram Vaani raised a $500,000 equity investment round to expand its team, move into new markets and grow its call volume. Investors included the Indian Angel Network, which made its first social venture investment, and Digital News Ventures, the seed-stage equity fund of theMedia Development Investment Fund. One year later, theEconomic Times, India's leading business newspaper,命名Gram Vaani among 14 startups to watch in 2014.

Gram Vaani partners with non-government organizations, international development agencies, universities and corporations. Gram Vaani provides the technical infrastructure; its partners provide the content. It has worked with Merck and the White Ribbon Alliance for Safe Motherhood to allow women to use Gram Vaani's voiced-based platform to review the quality of care they get from clinics. Its campaign with Oxfam around violence against women in India reached 400,000 households and generated 400 messages from the community.

The Mobile Vaani platform has become the voice of rural Indians,according to local journalists. "Villagers, long neglected by the government and media alike, have finally got a platform where they can discuss issues regarding health, unemployment and education without fear and be reasonably confident of receiving a reply from the concerned authorities," wrote one reporter.

Investors and international partners recognize Gram Vaani's large potential user base and increasing ability to share their stories. With the investment round in hand, Sethstated, "We are touching 2 million users already but that is only the tip of the iceberg."
