JISHNU SEN: A LIFE IN ADVERTISING, RETAIL, AND STARTUPS REMEMBERED

The advertising world mourns the passing of Jishnu Sen, former CEO of Grey India, who died in Bengaluru after a prolonged illness. With a career spanning three decades across agencies, retail and startups, Sen is remembered as a strategist, mentor and industry builder whose influence shaped Indian advertising and beyond.

Jishnu Sen’s career was a masterclass in versatility and vision. Beginning at J Walter Thompson in the 1990s, he quickly established himself as a strategist of rare calibre. His tenure at Young & Rubicam in New York, where he managed Colgate-Palmolive’s Asia-Pacific account, showcased his ability to blend global insight with local nuance. Returning to India, Sen’s defining chapter unfolded at Grey India, where he rose from COO to CEO. Under his leadership, Grey India achieved unprecedented growth, breaking into the top five of the Brand Equity Agency Reckoner rankings for the first time.

Sen’s trajectory was not confined to advertising. He brought his sharp intellect and consumer understanding to retail, serving as Chief Marketing Officer at Big Bazaar. His work there demonstrated his ability to adapt to India’s rapidly evolving retail landscape, marrying data-driven strategy with mass-market appeal. Later, he lent his expertise to startups such as Porter and Dealshare, as well as Bergner India, helping young businesses scale with the same rigour and creativity that defined his agency years.

Tributes from colleagues and industry leaders underline the breadth of his impact. Hari Krishnan of McCann India likened him to “a rare single malt, ageing well,” a nod to his enduring intellect and presence. Malvika Mehra, former Chief Creative Officer at Grey India, recalled his generosity in empowering creative leadership, while his cousin Shubho Sengupta described him as a man of “tremendous life force” who lived fully despite illness. Former colleagues often remembered his mantra: “strategy without passion is just paperwork,” a line that encapsulated his philosophy of blending rigour with energy.

Sen’s legacy lies not only in the campaigns he oversaw or the businesses he helped build, but in the people he mentored. He was known for nurturing talent, encouraging bold ideas, and inspiring teams to think beyond conventional boundaries. His influence extended across advertising, retail innovation and disruptive startups, making him one of the few leaders to straddle multiple worlds with equal ease.

With nearly 35 years of experience, Jishnu Sen leaves behind a legacy that is both professional and personal. He was a strategist, mentor, leader and friend, remembered for his intellect, warmth and ability to inspire. His passing marks the end of an era, but his lessons and energy will continue to resonate across the industry.
