The Stack Raises ₹21.5 Cr as Demand for Supplements Grows

Goa-based The Stack has raised ₹21.5 crore (~$2.2 Mn) in a seed round co-led by Sauce, OTP Ventures and Huddle Ventures, with AYRA Ventures also putting in money.

Here’s the number that stands out: this fresh round is almost as large as the entire valuation The Stack carried just nine months ago. The company’s first institutional round ₹5.5 crore in January reportedly valued it at around ₹27.5 crore. Raising ₹21.5 crore on top of that implies a sharp step-up, even though the new valuation itself hasn’t been disclosed.

What makes this bet unusual is the company’s restraint The Stack sells just five products, in a category where most D2C brands chase shelf-space through SKU explosion.

The Details

• Amount raised ₹21.5 Cr (~$2.2 Mn), seed round
• Co-leads Sauce, OTP Ventures, Huddle Ventures
• Also participating AYRA Ventures
• Total disclosed funding to date ₹27 Cr (₹5.5 Cr pre-seed in Jan 2026 + this ₹21.5 Cr round)
• Prior valuation ₹27.5 Cr (as of the January round)
• Implied signal New round size nearly matches the last valuation pointing to a meaningfully higher mark this time, even without an official number

Five Products, Not Fifty

Founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack builds supplements around clinically studied ingredients and minimal formulations.

Its current lineup covers sleep, gut health and general functional wellness. Iron and Omega-3 are next in line.

That narrow catalogue is a deliberate contrast to competitors like Wellbeing Nutrition, Supply6 and Trunativ, who typically run wider product ranges to capture more search traffic and shelf categories.

The Numbers Behind the 5x Growth Claim

The Stack says it has grown 5x in six months since its January round, and is now targeting 6-7x growth in FY27 over FY26.

The retention numbers back up some of that momentum: one in three customers reorder within six months, and many pay upfront for 6-12 month subscriptions a strong signal for a category notorious for one-time purchases.

The business is also concentrated the top 10% of customers drive 30% of revenue, with much of its new customer growth coming through referrals rather than paid acquisition.

Where the Money Goes

The capital will fund team expansion, R&D, and a wider product portfolio, alongside a push into tier 2 and tier 3 cities beyond its current metro base.

Betting fresh capital on deepening a five-SKU catalogue rather than diversifying fast is a slower, more capital-intensive path than most D2C playbooks. It only works if retention numbers like the reorder rate hold up as the customer base scales beyond early adopters.

Why the Growth Target Looks Optimistic

Projecting 6-7x growth off a 5x base in just six months is an aggressive ask, and the retention numbers that support it one in three reordering, top 10% driving 30% of revenue are still early-stage signals from a small, likely loyalist customer base.

As The Stack expands into tier 2 and 3 cities, it will be selling to a less brand-aware, less loyal audience than the early adopters who delivered its current numbers. Repeat rates and subscription behaviour typically soften as a D2C brand scales past its first core audience which makes strong growth likely, but the specific 6-7x target harder to bank on.

The Bottom Line

The real test for The Stack isn’t whether it can raise money on five products it’s whether reorder rates built on loyalists survive contact with tier 2 and 3 India.
