Sabyasachi Mitter

Founder and Managing Director, ibs Fulcro. Building India's digital marketing and technology industry since before most agencies had a digital practice at all.

Current Role

Sabyasachi Mitter is the Founder and Managing Director of ibs Fulcro, a role he has held since founding the company in February 2003. Over more than two decades, he has led the agency through three names and two deliberate reinventions, from Interface Business Solutions, to Fulcro, to today's ibs fulcro, while building a client roster spanning Tata Motors, Kotak, NPCI, P&G, ASUS, Hero MotoCorp, and dozens of other enterprise brands. The full story of that history is on our About page.

Before ibs Fulcro: Asian Paints

From 1996 to 2003, Sabyasachi worked at Asian Paints, including roles as Manager, Marketing and Brand Manager, joining directly after his PGDM at IIM Calcutta during the early days of the internet in India. According to his own account, he was directly involved in the marketing behind Colour World, the in-store shade-selection concept, and Home Solutions, a dial-in home painting service, both real Asian Paints initiatives from that era. Home Solutions has since evolved into what the company now operates as Asian Paints Beautiful Homes, still active today.

Education

Post Graduate Diploma in Management (PGDM), Indian Institute of Management, Calcutta, specialising in Marketing (1994–1996). Bachelor of Engineering in Metallurgy, Jadavpur University (1990–1994). Schooling at St. Xavier's Collegiate School and St. Xavier's College, Calcutta.

Industry Standing

Sabyasachi's standing in the Indian advertising and marketing industry goes beyond running ibs fulcro itself. He was named to Pitch Magazine's “Top 100 Powerful Digital Mavens of India” list in December 2012, and has been repeatedly invited to help judge the industry's own best work: on the jury for IDMA (2017), appointed Jury Chair of the Technology category at the ABBY One Show Awards (2023), and named Jury Chairperson for the Digital category at MADDYS (2026), a role he holds today.

He led Kotak Mahindra Bank's #HashtagBanking campaign to becoming the first Indian bank to win the Best New Product award at EFMA in Barcelona, a globally recognised innovation body in retail financial services. The full story is on the #HashtagBanking case study.
