Until recently, Raj Ramalinga Mantena wasn’t a name many Indians were familiar with. Today, he’s being talked about globally, thanks to a wedding that turned Udaipur into a glittering stage for Hollywood, Bollywood and business royalty.
Mantena, born in Vijayawada, Andhra Pradesh, is an Indian-American entrepreneur who built his fortune at the intersection of technology and medicine. After earning a degree in Computer Science from Jawaharlal Nehru Technological University and a clinical pharmacy qualification from the University of Maryland, he moved to the US in the 1980s.
He founded OncoScripts in the 1990s, one of the first oncology-focused pharmacies in the US. In 1997, he created the International Oncology Network (ION), later acquired by AmerisourceBergen. In the early 2000s, he launched ICORE Healthcare, a pioneer in managing specialty healthcare costs.
Mantena’s current ventures include Ingenus Pharmaceuticals, a global generics player with operations across the US, Switzerland and India, and Integra Connect, a health-tech firm specialising in oncology care and value-based solutions. Ingenus focuses on affordable generic drugs, while Integra Connect leverages data analytics to improve cancer care outcomes.
Contrary to what’s widely reported, Mantena is unlikely to be a ‘billionaire’. Publicly available information suggests his net worth is around USD 20 million (Rs 167 crore), and the valuation of his company is estimated at USD 35 million (as of September 2025). It’s important to note that it is a privately held company and public information is limited. Mantena reportedly bought a Rs 400-crore luxury property in 2023 with 16 bedrooms and a private beach in Florida.
His wealth, however, has been on full display during the wedding of his daughter, Netra Mantena, to tech entrepreneur Vamsi Gadiraju in Udaipur. The four-day extravaganza unfolded across iconic venues like The Leela Palace and Jagmandir, with décor curated by Wizcraft Weddings.
The guest list featured superstars and the who’s who, including Jennifer Lopez, Justin Bieber, Donald Trump Jr, Hrithik Roshan, Ranveer Singh, Madhuri Dixit and Karan Johar. Entertainment included Tiësto, Black Coffee and Cirque du Soleil, alongside Bollywood performances that had Trump Jr. dancing to Ranveer Singh’s beats.
