Engineering graduates Rahul Arepaka and George Mathew founded Harvested Labs in 2023 and built Rakshak, an AI-powered laser weeder that burns weeds instead of using pesticides. The tractor-mounted robot uses computer vision to detect weeds and has run pilots in farms. Mahindra University invested ₹20 lakh and the startup raised about ₹5 crore in pre-seed funding.
