Google has launched its Google Impact Challenge in India, asking the country's non-profit organizations how they would use technology to tackle social problems in India and around the world. The four submissions judged as the best will each receive Rs 3 crore and technical assistance from Google to help make their project a reality. Applications to the competition open today and Indian non-profits are invited to apply online by 5th September at g.co/indiachallenge. A team from Google will review applications and announce 10 finalists on October 21. The top 10 finalists will then be announced and the public will be able to cast a vote for their favourite projects.
