Retirement has long been viewed as the end of professional engagement, yet in recent years it has increasingly emerged as a new beginning for entrepreneurial pursuits. Retired employees, enriched with decades of knowledge, professional networks, and managerial skills, possess significant potential to transition into entrepreneurship. This paper adopts an exploratory mixed-method design, drawing upon secondary data, case illustrations, and proposed survey/interview methods, to examine the feasibility of retirees in India starting post-retirement enterprises by leveraging their accumulated human capital. Indicative findings suggest that while financial necessity is a motivating factor, psychological and social drivers such as purpose, identity, and dignity play an equally strong role. Retirees are particularly successful in knowledge-driven sectors (consultancy, education, healthcare, digital platforms), whereas ventures in capital-intensive or volatile markets face higher failure risks. The study concludes that with targeted policy and institutional support, senior entrepreneurship can become a significant contributor to inclusive growth and active ageing in India
