from building India’s iconic brands to launching a founder-led advisory, Calvin John unveils Calvinysm

After two and a half decades of shaping some of India’s most iconic consumer brands, Calvin John, one of the country’s most respected marketing leaders, today announced the launch of Calvinysm, a founder-led strategic brand growth and marketing advisory. From nurturing market-dominating brands like Bisleri, Titan, Tanishq, Surf, Rin and McDowell’s No.1, to launching and scaling category-defining brands such as Mia by Tanishq, CaratLane, and Glance, John has spent 25+ years building businesses from the inside. Calvinysm marks his transition from corporate leadership to independent advisory.

“For years, founders and CMOs have reached out for perspective, often outside formal mandates and structures. Calvinysm is a natural extension of catalysing growth for ambitious brands,” said Calvin John, Founder, Calvinysm.

Calvinysm operates as a deep-in-the-room advisory, working closely with founders and leadership teams on growth strategy, marketing transformation, digital narrative and brand architecture. John’s career spans India, North America, Japan, the Middle East and Southeast Asia, giving Calvinysm a global vantage point on consumer behaviour and business transformation.

“After two and a half decades of building brands and scaling business from zero to significant scale, it’s clear that brands need clearer thinking, sharper choices and the ability to execute with speed,” said Calvin John, Founder, Calvinysm. “Calvinysm is built for this moment. It exists to help ambitious brands grow with clarity and conviction, without the layers, delays or dilution that come with traditional structures.”

Calvinysm will work with growth-stage companies, founder-led businesses and legacy brands seeking reinvention, partnering closely with leadership teams to drive meaningful and sustainable growth. It operates independently and partners with leading execution firms to deliver growth.
