It all began in 2016, in the serene hills of Dehradun, where a small team with a big dream came together, not in a boardroom, but in a R&D lab nestled in the Himalayas.
We were united by one powerful belief: no life should ever be lost just because medical help wasn’t close enough.
Our mission has always been clear: to make medical diagnostics accessible, affordable, and truly life-saving, even in the most remote corners of India.
That vision found national recognition when our work was celebrated on Shark Tank India Season 1, where we earned an All-Shark investment, a proud reminder that what started as a quiet dream in the mountains is now a movement with real momentum.
