What The Stack does
The Stack is an India-based direct-to-consumer supplements brand operating under the legal entity Stack Nutraceuticals Pvt. Ltd., founded in 2024 in Panjim by co-founders Shreya Jain and Kshitij Rihal. The company formulates and sells science-backed nutritional supplements targeting three functional wellness categories — sleep, gut health, and post-exercise recovery — to health-conscious Indian consumers in urban metro markets. Its product portfolio is organized into two stacks: a Sleep Stack comprising Deep Rest (MetaMag® Magnesium Bisglycinate sourced from Balchem USA), Dream On (Glycine), and a Complete Sleep Stack bundle; and a Gut Stack comprising Daily Gut Balance (L. Acidophilus NCFM probiotic with PHGG prebiotic), a Light & Regular Combo bundle, Gut Immune Support (EpiCor® 500mg postbiotic from Cargill), and Daily Fibre Bomb (multi-fiber prebiotic). All formulations use clinically studied branded ingredients and are manufactured in WHO-GMP and US FDA approved facilities, with explicit positioning around full ingredient transparency and no proprietary blends.
The Stack operates a pure-play DTC business model: all sales occur through its own e-commerce storefront at thestack.club, with no third-party retail, marketplace, or reseller distribution. Pricing is unit-based (pay-as-you-go) across SKUs in the ₹889-₹2,579 range, with no subscription component. Customer acquisition is driven by content marketing (wellness blog), organic social (Instagram), SEO, email newsletters, and a ReferRush-powered referral and loyalty program that delivers a 10% referred-customer discount. The company reports strong early traction — 40x growth on select products within 12 months and 35-50% repeat purchase rates at the SKU level — supported by 945 verified Judge.me reviews and platinum-tier badges for transparent shop practices and verified reviews.
The company is privately held and venture-backed, having raised ₹5.5 crore (~$600K USD) in a pre-seed funding round in 2024 co-led by OTP Ventures and Huddle Ventures, with participation from angel investors. Funds are allocated to R&D, product pipeline expansion, team building, and brand development. Headcount remains small (1-10, with only the two co-founders formally identified), and operating scope is single-country (India). There is no public revenue disclosure, no identified parent or subsidiary structure, and no evidence of AI/ML capabilities, M&A activity, or international expansion.
