Seed funding details
The Stack announced on 14 October 2026 that it raised Rs 21.5 Cr in a seed round. The funding was co-led by Sauce, OTP Ventures, and Huddle Ventures, with participation from AYRA Ventures.
The capital injection follows an earlier institutional round of Rs 5.5 Cr raised by the startup in January 2026.
Clinically studied supplements
Founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack is a direct-to-consumer health brand based in Goa, India. It sells products focused on sleep, recovery, functional health, and gut health through its own website.
The brand targets consumers looking for science-backed nutrition supplements. Its five product formulations feature clinically studied ingredients and transparent formulations, combining magnesium bisglycinate, glycine, prebiotics, and probiotics.
Customer metrics and business traction
The company reported that it has grown 5X since its January funding and is targeting 6-7X growth in FY27 compared with FY26. It claims one in three customers places a second order within six months, and several subscribe for periods ranging from six to twelve months.
The Stack's top 10% of customers account for 30% of its revenue, with word of mouth and referrals driving new customer acquisition.
"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 co-founder Kshitij Rihal.
Growth plans and market context
The Stack intends to use the seed funding to expand its team, invest in research and development, and broaden its product portfolio. Over the next three years, the company aims to become one of India's most trusted supplement brands.
The company operates in India's health and wellness market alongside competitors such as Wellbeing Nutrition, Supply6, and Trunativ.
