In a country like India that has a vast but higly scattered NGO sector, lack of reliable information is a serious bottleneck for philanthropy to grow. As an aggregator of NGO information, GuideStar India is playing a vital role in building the ecosystem for a philanthropy marketplace. GuideStar India pursues a ground up model to collect information from NGOs. It also receives data from Government bodies like CAPART, the Planning Commission, the National Trust of the Ministry of Social Justice and Empowerment and YASHADA. This data is often historic and incomplete. GuideStar India persistenly follows up with NGOs to clean up and update the data, while also educating NGOs to embrace transparency by consenting to put their information in the public domain. Verified information is made available in the public domain and is also fed back to the source including government sources.
