Mumbai, October 14: The Stack, a supplements brand focused on clinically studied ingredients and transparent formulations, has raised ₹21.5 crore in its latest funding round. The round was co-led by Sauce, OTP Ventures and Huddle Ventures.
“The supplements landscape in India is exploding with many brands and an overload of information for consumers. Given this landscape, Stack’s promise of minimal ingredients, gold standard quality and complete transparency is what attracts us as a consumer and investor.” said Manu Chandra, founder at Sauce.
The Stack raised its first institutional round of ₹5.5 crore in January, 2026 and has grown 5x in 6 months. It’s targeting to close FY26-27 at 6-7X growth of FY 25-26.
The Stack sells just five products as of today. One in three customers places a second order within six months, and many now pay for six to twelve months upfront through subscriptions. The top 10% of customers drive 30% of revenue. They see a strong inflow of new customers come through referrals and word of mouth.
“A lot of building The Stack has been saying no. No to launching fifty products, no to trending ingredients we don’t believe in, no to upselling people things they don’t need. We’d rather have five products people keep coming back to than fifty they try once. We’re playing a long game, and our customers are rewarding that patience,” said Kshitij Rihal, Co-founder of The Stack.
“Many brands solve for distribution before getting the product right. Having backed Kshitij and Shreya since their earliest days, we’ve witnessed them do it the right way, staying true to their standards on formulation and efficacy, and their industry leading repeat rates prove it. With that foundation, we’re excited to double down as they expand across channels and make The Stack the go-to choice for India’s evolved supplements consumer.” said Ishaan Khosla, Partner at Huddle Ventures.”
The company will use the funds to grow its team, invest in research and development, and expand its product portfolio.
“Clean label and traceable sourcing have transformed how India eats, and supplements are next. The Stack is leading that shift with world-class formulations, globally sourced raw materials and complete transparency. As a user myself, I am thrilled to back Kshitij and Shreya, as they build the most trusted brand in the category” added Samina Hamied, Founder & Managing Partner, AYRA Ventures, who participated in the round.
Over the next three years, The Stack wants to become India’s most trusted supplements brand.
“We want The Stack to be synonymous with trust and transparency. When we launch a product, we want people to already know we’ve done the homework on the ingredients, the dosage and the sourcing, and that we’re not trying to upsell them. That’s the bar,” added Shreya, Co-founder of The Stack.
“We believe the largest supplement brands of the next decade will be focused and use case led, not catalogues of everything. The Stack is the first in India built that way, and the category will increasingly be measured against them,” Suhail Sameer from OTP Ventures added
