Founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack is a consumer health startup that formulates supplements using clinically studied ingredients sourced from global suppliers. The company follows a limited, quality-first product strategy, concentrating on clearly defined use cases like sleep support and gut health while maintaining end-to-end supply-chain transparency. Over the past year, The Stack says it has built a multi-category consumer health business with improving unit economics, and certain products have grown more than 40× in 12 months. Repeat purchase rates range from 35 % to 50 % at the SKU level within mature customer cohorts, indicating strong retention. The newly raised capital will be deployed toward R&D, expanding the product pipeline, hiring its early team, and enhancing branding and packaging. Looking ahead, the founders plan to keep the portfolio intentionally small, focusing on highly differentiated, science-backed formulations that address lifestyle-linked health concerns. Their emphasis on transparency and evidence-based ingredients positions them to capture health-conscious consumers seeking credible supplement options.
