Rama Raju Mantena, the Indian-American founder of Ingenus Pharmaceuticals, drew national attention in India after hosting one of 2025’s most viral weddings in Udaipur.
The wedding of Mantena’s daughter Netra to San Francisco entrepreneur Vamsi Gadiraju brought together a high-profile guest list at iconic palace-style hotel venues on Lake Pichola.

Born in Vijayawada, Andhra Pradesh, Mantena moved to the United States in the 1980s after studying engineering and computer science at Jawaharlal Nehru Technological University and later clinical pharmacy at the University of Maryland.
His blend of technical and medical training shaped his early roles at P4 Healthcare and led him to establish International Oncology Network, ICORE Healthcare, and OncoScripts, each focused on oncology care and specialty pharmacy systems.
In 2007 he launched Ingenus Pharmaceuticals, a vertically integrated manufacturer of generic and specialty drugs with operations in the United States, Switzerland, and India. The company’s stated mission is to develop affordable medications “without compromise,” placing Mantena among key contributors in the generics sector.
Mantena’s public profile has remained limited, surfacing mainly in philanthropic contexts, including his 2017 donation of a garland made of 1,008 gold coins to Tirumala Tirupati Devasthanams. His acquisition of a large beachfront estate in Florida added to speculation that his financial standing exceeds publicly cited estimates.
The wedding offered an uncommon view into Mantena’s four-decade rise in pharmaceuticals, highlighting how a figure long operating outside public attention briefly took center stage in one of India’s biggest social events of the year.
