Ratan Tata, chairman emeritus at Tata Sons, invested an undisclosed amount in a pharmaceutical start-up Generic Aadhaar, in his personal capacity. The startup is run by 18-year-old Arjun Deshpande, who is the founder and CEO. The Mumbai-based teenager began his venture two years ago with an aim to bring affordable medicines to the masses. In the coming months, Deshpande plans to partner with 1,000 pharmacies on a franchisee-based model and expand his reach to cities like Gujarat, Tamil Nadu, Andhra Pradesh and New Delhi. Generic Aadhaar will provide all the support to the unorganized sector by bringing the right technology, IT infrastructure and branding to the forefront. The company has about 55 employees, which include pharmacists, IT engineers and marketing professionals.
