Smart India Hackathon is a nationwide initiative to provide students with a platform to solve some of the pressing problems we face in our daily lives, and thus inculcate a culture of product innovation and a mindset of problem-solving. The first four editions SIH2017, SIH2018, SIH2019, SIH2020 and SIH2022 proved to be extremely successful in promoting innovation out-of-the-box thinking in young minds, especially engineering students from across India.
