In December 2015, The Lemelson Foundation, an organisation that believes that invention can solve many of the biggest economic and social challenges of our time, embarked on a major partnership with GMin by investing $ 766,100 (Ksh.76 million) in GMin for the period of 2016 to 2019. In partnership with The Lemelson Foundation over the next three years, GMin will launch three Innovation Labs and expand their Innovate Challenge program in Kenya, enabling young learners to develop problem-solving, collaboration, and critical thinking skills, and provide a model for learner centred, participatory, and project-based approach to education.
