Consumer health and supplements startup The Stack has raised ₹5.5 crore in a pre-seed funding round, co-led by OTP Ventures and Huddle Ventures, with participation from a group of angel investors.
The company said the fresh capital will be used to strengthen research and development, expand its product pipeline, build the early leadership and execution team, and invest in branding and packaging.
Building a Science-First Supplements Brand
Co-founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack is positioning itself as a science-backed, quality first supplements brand focused on a narrow set of health outcomes impacted by modern lifestyles.
The company emphasises clinically studied global ingredients, transparent sourcing and a tightly controlled supply chain. Rather than pursuing rapid SKU expansion, The Stack is adopting a focused portfolio strategy, prioritising a small number of well-researched products with clearly defined benefits.
Its initial product focus areas include sleep, gut health and metabolic wellbeing.
Founders’ Background
Kshitij Rihal previously co-founded and scaled Flo Mattress, while Shreya Jain earlier founded a technology startup that was acqui hired by Byju’s.
The founders said their combined experience across consumer brands and technology has shaped The Stack’s emphasis on long-term customer trust over short-term growth.
Early Traction and Unit Economics
Over the past 12 months, The Stack claims to have built a multi category consumer health brand with strong underlying unit economics. According to the company, select products have scaled more than 40x within a year, supported by 35–50% SKU-level repeat rates in mature customer cohorts.
The company said this repeat behaviour reflects portfolio-level progression and sustained usage, rather than one time, promotion driven purchases.
Why It Matters
Investor interest in supplements and preventive health brands has been rising as Indian consumers become more discerning about ingredient quality, efficacy and transparency. The Stack’s narrow, science-led approach positions it differently in a crowded market dominated by broad spectrum and marketing-heavy offerings.
