The Stack, a supplements company that prioritises clinically researched ingredients and transparent formulations, has secured Rs 21.5 crore in a seed funding round jointly led by Sauce, OTP Ventures and Huddle Ventures.
The Goa-based startup had previously raised Rs 5.5 crore in a pre-seed round in January this year, co-led by OTP Ventures and Huddle Ventures, with backing from several angel investors.
The newly raised capital will go towards team expansion, research and development, and broadening its product portfolio, the company said in a press release.
Founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack develops science-backed supplements using globally sourced ingredients supported by clinical research. Its approach centres on formulation transparency and delivering long-term benefits to consumers.
Adopting a quality-led strategy, the company maintains a focused product range covering key health categories, including sleep, gut health and functional health. It aims to establish an India-based supplements brand that meets international quality standards.
The Stack currently offers five products. According to the company, one in three customers makes a repeat purchase within six months, while several opt for subscriptions and pay upfront for periods of six to 12 months. Its top 10% of customers contribute 30% of revenue. The brand also attributes a significant share of new customer acquisition to referrals and word-of-mouth recommendations.
The company reported fivefold growth over the past six months and is aiming to achieve 6-7X growth in FY27 over FY26.
