At just 42, Kishin RK has become Singapore’s youngest billionaire, achieving success in the highly competitive world of real estate. His name now sits alongside some of the world’s wealthiest individuals, but his path to fortune has been far from conventional.

Born into a prominent property family, Kishin, whose full name is Kishin Raj Kumar, grew up immersed in business. His father, Raj Kumar Hiranandani, is a well-known figure in Singapore’s property sector. Despite this background, Kishin was determined from an early age to forge his own route.

He made his first property purchase at just 12 years old, guided by his father. That experience sparked a deep interest in real estate that has stayed with him throughout his life. At 18, he sold a flat gifted by his parents and used the proceeds to establish RB Capital Group in 2006. This move marked the beginning of his independent business journey.

Although he briefly considered other industries, such as finance and hospitality, Kishin’s passion for real estate always remained strongest. He has often spoken about the appeal of creating something lasting within the property sector.

RB Capital quickly became known for its focus on developing properties, rather than simply acquiring them. This distinctive approach helped Kishin set himself apart from others in the industry. Under his leadership, the company has developed several landmark projects in Singapore, including the InterContinental Singapore Robertson Quay and Holiday Inn Singapore Little India.

Kishin formally joined the family business in 2003. However, a major turning point came in 2011 when the family’s real estate empire was divided between his father and uncle. Following this split, Kishin and his father began managing a portfolio that is now worth close to US$10 billion. Together, they are considered one of the most influential partnerships in Singapore’s property market.

Their ambitions have also expanded beyond Singapore. In 2024, they established the RB Family Office in Abu Dhabi to manage their investments across the Middle East. This move was seen as a strategic step towards global expansion, taking advantage of the region’s investment-friendly environment.

According to Forbes, Kishin currently holds a net worth of US$1.6 billion, securing his position as Singapore’s youngest billionaire in 2025. When combined with his father’s wealth, their joint net worth is estimated at over US$3.15 billion.

Despite his immense financial success, Kishin is known for his modest and respectful manner. Those who work with him often describe his approachable attitude, noting that he treats everyone with the same level of respect, from senior executives to front-line staff.

His charitable efforts have also received attention. During the COVID-19 pandemic, Kishin co-founded Tiffin Labs, a cloud kitchen business, and launched the “Food is Love” programme, which provided meals to vulnerable groups in Singapore.

Kishin RK’s story is not just one of wealth and inheritance. It is also about vision, hard work and the drive to build something of his own.
