About Subham
Subham started The Shizz in 2020 with Antara Dutta on one premise: that a consumer brand grows fastest when media, creative and conversion are run by one accountable team against checkout revenue rather than channel metrics. Six years on, that model has been applied to 160+ brands, ₹150 Cr+ of managed ad spend and ₹450 Cr+ of attributed revenue, with an average client relationship of 1.5 years.
His day-to-day is the performance side of the studio: Meta, Google, Amazon and quick-commerce media, offer and pricing architecture, retention economics, attribution and the founder-level growth planning behind the published case studies, from My Pahadi Dukaan’s ₹12L to ₹1.2 Cr a month to Svasthyaa’s zero to ₹11 lakh a month fully prepaid.
