More than four years after leaving Amazon, Jeff Bezos is back in the game. The billionaire announced in 2025, that he would be serving as the co-chief executive (co-CEO) of Project Prometheus, a new AI company. He would be sharing the title with Vikram ‘Vik’ Bajaj, an Indian-origin scientist and entrepreneur.This move marks Bezos’s first operational role since stepping down as the CEO of Amazon in July 2021. Prometheus, is already promising the future by having raised around $12 billion in funding, with a valuation of $41 billion. While much is known about Bezos, who is his partner in AI, Vik Bajaj?Meet Vik BajajBorn in 1977 in Canada, Bajaj grew up in a family of Indian immigrants who were among the early generations to settle in Canada after India’s independence. While his father performed leadership roles in public and private education, his mother worked as a physician.He completed a combined Bachelor of Arts and Master of Science degree in biochemistry at the University of Pennsylvania. Then he went on to earn a PhD in Physical Chemistry from the Massachusetts Institute of Technology (MIT). Next, he pursued a postdoctoral research position at the University of California, Berkeley.Initially, Bajaj entered academia. He worked as a scientist at Lawrence Berkeley National Laboratory and as a principal investigator at the University of California, Berkeley.However, in 2013, he moved into technology. He joined Google X, the company's research and development division known for pursuing ambitious long-term projects. Working with a team led by molecular biologist Andy Conrad and alongside Google co-founder Sergey Brin. He helped establish Google Life Sciences, the unit that later became Verily under Alphabet, Google’s parent company.As co-founder and Chief Scientific Officer of Google Life Sciences, Bajaj worked on applying data science and advanced technologies to healthcare and biology. He also held a director-level position at Google X and was involved in early-stage projects that eventually evolved into businesses such as autonomous vehicle company Waymo and drone-delivery venture Wing.In 2016, he left Google to join cancer detection company Grail as Chief Scientific Officer. He said the move was influenced in part by his father’s death from cancer in 2015. While he worked at the company for just a year, he remained on its Scientific Advisory Board until 2021, when Grail was acquired by Illumina.Thus, in 2017 he moved to a more backend work and joined healthcare-focused investment firm Foresite Capital as managing director. A year later, he became co-founder and Chief Executive Officer of Foresite Labs, the firm’s startup incubation platform focused on combining healthcare, life sciences and data science.It was from Foresite Labs that Prometheus emerged. Bezos and Bajaj began working on the project in late 2024 and launched the company the next year. According to reports, Prometheus seeks to shorten the path from concept to production by applying AI to the design and development of complex products. Investors in the company include JPMorgan, BlackRock, Goldman Sachs, DST Global, Arch Venture Partners and Bezos himself. Moreover, to focus on the venture, Bajaj also stepped down as CEO of Foresite Labs in February 2026.Along with his startup work, he continued to hold roles in research and public service. He serves as a non-executive director at Genomics England, a company owned by the United Kingdom's Department of Health and Social Care. He is also an adjunct professor at Stanford School of Medicine, a role he has held for more than a decade.As of now, Bajaj is closely being watched by the world, at the centre of one of the most closely watched AI ventures in the world.
