The Stack Raises ₹21.5 Crore: How This Supplements Startup Plans to Expand Its Product Range

Indian supplements brand The Stack has raised ₹21.5 crore in a funding round co-led by Sauce, OTP Ventures and Huddle Ventures, with participation from AYRA Ventures. The startup plans to invest in research and development, expand its team and introduce new products as it looks to build a trusted consumer health brand in India.

India’s health and wellness market is attracting entrepreneurs and investors looking beyond conventional nutrition products. Consumers are increasingly seeking supplements designed for specific needs, including sleep, gut health and everyday wellness.

Bengaluru-founded The Stack is taking a focused approach to this opportunity. Rather than launching a large catalogue of products, the company has built its business around a limited range of supplements, transparent formulations and ingredients backed by scientific research.

The latest funding will help the startup expand its product portfolio while maintaining its emphasis on product quality and repeat customer relationships.

The investment also highlights growing interest in direct-to-consumer (D2C) health and wellness brands that aim to differentiate themselves through formulation, transparency and customer trust.

What Does The Stack Do?

Founded in 2024 by Shreya Jain and Kshitij Rihal, The Stack is a consumer health brand focused on dietary supplements designed for specific wellness needs.

Its current portfolio includes five products covering areas such as sleep, gut health and functional health. The company uses ingredients including magnesium bisglycinate, glycine, prebiotics and probiotics in its formulations.

The brand’s approach centres on three principles.

1. Focused product development

The Stack has deliberately maintained a small product portfolio rather than expanding into numerous categories at once.

The idea is to develop products that address clearly defined customer needs and encourage repeat purchases, rather than relying on a large catalogue to attract attention.

2. Transparent formulations

The company emphasises ingredient transparency, sourcing information and quality standards.

In the supplements market, consumers may find it difficult to compare formulations, ingredient quantities and evidence supporting product claims. The Stack aims to make these details easier to understand.

3. Science-led ingredient selection

The brand says it prioritises clinically studied ingredients and evaluates products based on their intended benefits.

The approach reflects a broader shift among some wellness companies towards more focused formulations instead of adding trending ingredients simply for marketing appeal.

Scientific evidence for an ingredient does not automatically establish that every finished supplement delivers a particular benefit. Product formulation, dosage, safety and individual circumstances also matter.

How Will The Stack Use Its Fresh Funding?

The company plans to use the ₹21.5 crore funding across three primary priorities.

Expanding research and development

Research and development will be important as The Stack explores new formulations and additional product categories.

The company has indicated that iron and Omega-3 supplements are among the next additions to its portfolio. These products require careful formulation and quality evaluation, particularly because nutritional needs and appropriate supplementation can vary among individuals.

Broadening the product portfolio

The Stack intends to introduce additional products while retaining its focus on clearly defined wellness needs.

This strategy could help the brand serve existing customers looking for complementary products while attracting new consumers through additional use cases.

However, expanding too quickly can increase inventory complexity, sourcing requirements and customer acquisition costs. Maintaining product quality while growing the range will be an important consideration.

Expanding the team and distribution

The funding will also support hiring and the company’s broader growth plans.

Until now, The Stack has relied heavily on its own website and direct customer communication. The company plans to expand into large e-commerce marketplaces and explore additional sales channels, including quick commerce, over the next 12 to 18 months.

A wider distribution network could improve product discovery and convenience. It will also expose the company to more competition and potentially different channel economics.

The Stack’s Growth Strategy: Why Repeat Customers Matter

One of the more notable aspects of The Stack’s business is its reported customer retention.

According to the company, approximately one in three customers places a second order within six months. Its top 10% of customers account for around 30% of revenue.

The company has also reported that some customers opt for subscriptions covering six to twelve months.

These figures are company-reported metrics rather than independently audited results, but they provide an indication of the business model The Stack is trying to build.

For a supplements brand, repeat purchases can be particularly important because customers may buy products regularly when they find them suitable for their needs.

A strong repeat-purchase rate can reduce dependence on continually acquiring new customers through paid advertising. It may also provide a more predictable revenue base.

However, retention alone does not establish profitability. A business must also account for product costs, discounts, fulfilment, returns, marketing and the economics of subscription programmes.

The Stack’s challenge will be to preserve customer trust and repeat demand as it expands its catalogue and distribution.

Why Is The Stack Avoiding a Large Product Catalogue?

The consumer supplements market includes products spanning vitamins, minerals, protein, gut health, sleep, sports nutrition and specialised wellness needs.

For new brands, launching products across multiple categories can appear to be a quick way to increase revenue opportunities. But every category can require different ingredient suppliers, formulation expertise, quality controls and customer education.

The Stack’s strategy is to concentrate on a smaller range and expand when it believes it can offer a meaningful product proposition.

This has several potential advantages:

• Greater product focus: More resources can be devoted to formulation and quality.
• Simpler inventory management: A smaller catalogue can reduce operational complexity.
• Clearer brand positioning: Customers may find it easier to understand what the brand specialises in.
• Repeat-purchase opportunities: Products that meet recurring needs may encourage customers to return.
• More disciplined expansion: New products can be evaluated against specific customer needs rather than short-term trends.

The trade-off is that a focused portfolio may limit cross-selling opportunities and leave the business more dependent on a small number of products.

The company’s ability to expand without losing its focus will be important as competition increases.

How Does The Stack Compare With Other Indian Supplements Brands?

The Stack operates in a competitive market that includes established wellness companies and newer digital-first brands.

Competitors and comparable businesses include Wellbeing Nutrition, Supply6 and TruNativ, although their product portfolios and positioning differ.

The Stack is seeking to distinguish itself through a combination of limited product selection, transparent formulations and an emphasis on ingredients supported by scientific research.

Unlike businesses that pursue growth primarily through extensive product catalogues, The Stack has so far focused on a small number of wellness categories.

This positioning could appeal to consumers who want clearer information about ingredients and intended use. But trust is built over time through consistent quality, accurate claims, safety practices and reliable customer experiences.

As the business expands into marketplaces and quick commerce, maintaining that positioning across different channels will become increasingly important.

What Does The Stack’s Funding Say About India’s D2C Wellness Market?

The funding reflects continued investor interest in consumer brands that combine online distribution with differentiated products and repeat-purchase potential.

The supplements category presents opportunities because products can serve recurring consumer needs. At the same time, the market requires careful attention to ingredient quality, product claims, regulatory compliance and consumer education.

For D2C businesses, the challenge is not simply to acquire customers. They must build trust, encourage repeat purchases and establish sustainable unit economics.

The Stack’s funding will allow it to invest in product development and broaden distribution, but the next stage of growth will require balancing these investments with operational discipline.

Its reported repeat-purchase metrics and focused product strategy offer a starting point. Whether these translate into durable growth will depend on customer satisfaction, product performance and the economics of expansion.

What Lies Ahead for The Stack?

The Stack is targeting substantial growth in FY2026–27 compared with FY2025–26. The company has stated an ambition to achieve six- to seven-fold growth over that period, following reported five-fold growth in the six months after its January 2026 funding round.

These are company targets, not guaranteed outcomes.

The next phase will involve expanding its portfolio, developing new formulations, strengthening distribution and reaching more customers.

The planned launches in categories such as iron and Omega-3 will test the company’s ability to extend its product range while maintaining its quality-first positioning.

Its entry into larger marketplaces and quick commerce could also change how customers discover and purchase its products.

For investors and competitors, the key indicators to watch will include repeat-purchase rates, new product adoption, revenue growth, distribution expansion and the company’s ability to acquire customers profitably.

The ₹21.5 crore funding round gives The Stack additional resources to pursue these goals. Its long-term success will depend on whether it can turn a focused product strategy into a trusted and commercially sustainable consumer health business.
