S unil Vachani is a self-made Indian billionaire who is the founder and chairman of Dixon Technologies, one of India's largest and most successful electronics contract manufacturers. He founded the company in 1993 with a small loan from his father. He has since built it into a major player in the electronics manufacturing services (EMS) industry, with a focus on producing a wide range of consumer electronics for major international and domestic brands.

Dixon is a key manufacturing partner for companies like Samsung, LG, and Xiaomi, producing products like televisions, smartphones, and washing machines in its factories in India. The company's growth has been massively fueled by the Indian government's "Make in India" initiative, which has encouraged global brands to manufacture their products locally. He took the company public in a highly successful IPO in 2017, and his family's large controlling stake is the source of his billion-dollar fortune.
