New Delhi, January 2026: The Stack, a science-backed consumer health and supplements startup, has raised ₹5.5 crore in a pre-seed funding round, co-led by OTP Ventures and Huddle Ventures. The round also saw participation from a group of angel investors.
The fresh capital will be deployed toward research and development, expansion of the product pipeline, early team building, and strengthening branding and packaging, the company said in a statement.
Building a Science-First Supplements Brand
Founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack is focused on creating high-quality, clinically backed supplements using globally sourced, research-supported ingredients. The brand targets key health concerns shaped by modern lifestyles, including sleep, gut health, and overall metabolic balance.
Unlike mass-market supplement players, The Stack follows a narrow, quality-first approach, concentrating on a limited number of products with clearly defined benefits rather than chasing rapid category expansion.
The founders aim to build a trusted, India-born supplements brand that combines global quality benchmarks with local consumer insight, addressing gaps in transparency, ingredient quality, and efficacy within the nutrition market.
Experienced Founding Team
Co-founder Kshitij Rihal previously co-founded and scaled Flo Mattress, while Shreya Jain earlier founded a technology startup that was later acqui-hired by Byju’s. Their combined experience across consumer brands and technology-led startups has shaped The Stack’s disciplined, long-term approach to brand building.
Early Traction and Strong Repeat Behaviour
Over the past 12 months, The Stack claims to have built a multi-category consumer health brand with strong unit economics, focusing on sustainable growth rather than short-term customer acquisition.
According to the company, select products have scaled more than 40× within a year, supported by 35–50% SKU-wise repeat rates in mature customer cohorts. This performance indicates portfolio-level customer progression and sustained repeat usage, rather than one-time or promotion-driven demand.
The brand also highlights its end-to-end transparent supply chain, sourcing premium ingredients globally while maintaining strict quality controls across manufacturing and packaging.
Focused Growth Ahead
With the new funding, The Stack plans to deepen its investment in clinical research, formulation development, and customer education, while continuing to operate with a tight product portfolio.
As India’s supplements and preventive health market continues to expand, The Stack is positioning itself as a science-led, trust-driven alternative to traditional nutraceutical brands—targeting long-term customer value over rapid, unsustainable scale.
