BumbleB Trust’s first project is kalvi40 (கல்வி40), a free educational mobile application for Tamilnadu and Puducherry Government School Students. The Brand name Kalvi40 come from a Tamil Sangam literature Thirukkural ‘திருக்குறள் அதிகாரம் 40 – கல்வி’- as a sign of what Thiruvalluvar explained in his 40th chapter through his 10 verses about the importance of education in human life.

Project Kalvi40’s purpose is to uplift Government school rural students through EdTech, in a non-profit mode. Prem Kumar, founder of the BumbleB Trust designed the app with the goal of making students love education without making them to run behind marks. The mobile app is available on Google India playstore (45k+ installation) and 4500+ customized videos. Kalvi40’s backbone is our 500+ member volunteer group across 12+ countries; a mix of philanthropists, teachers, high school students, retired professionals, distributed worldwide.

Kalvi40 initiative is a classical example of how if citizens come together, the changes can be brought at grassroot level. Without any expectation, Kalvi40 volunteers have moulded a success story for the larger benefit of Government school students and Teachers.
