Supplements brand The Stack raises pre-seed funding

Supplements brand The Stack has raised Rs 5.5 crore in a pre-seed funding round co-led by OTP Ventures and Huddle Ventures, with participation from a group of angel investors.

The fresh funds will be used to invest in research and development, expand the product pipeline, build the early team, and improve branding and packaging, the company said in a press release.

Co-founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack is a supplements brand focused on building high-quality, science-backed products using clinically studied global ingredients. The brand focuses on key health areas impacted by modern lifestyles and follows a narrow, quality-first approach. It aims to build a trusted supplements brand from India by combining global standards with local insight.

Kshitij previously co-founded and scaled Flo Mattress, while Shreya earlier founded a technology startup that was acqui-hired by Byju’s.

The company emphasises key health areas such as sleep and gut health and plans to stay focused on a small number of well-researched products with clear benefits. It uses high-quality ingredients sourced globally and a supply chain that is transparent end to end.

Over the past 12 months, The Stack claims it has built a multi-category consumer health brand with strong underlying unit economics, focusing on long-term customer value. Select products have scaled more than 40× within a year, supported by 35–50% SKU-wise repeat rates in mature cohorts, reflecting sustained repeat behaviour and portfolio-level customer progression rather than one-time acquisition.
