On June 8, 2026, Zepto filed its updated DRHP with SEBI, revealing massive growth numbers that demand a closer look at the Swiggy Instamart product strategy. The numbers inside that filing stopped me: Zepto processed 210 million orders in the January to March 2026 quarter, while Swiggy Instamart processed 112.6 million. By examining these public filings, we can look past the lazy execution narratives and analyze the core strategic differences between India’s top quick-commerce giants.
Zepto was founded in 2021.
By two 19-year-olds who dropped out of Stanford.
In five years, they built a product that does nearly double the orders of Instamart — a service backed by Swiggy, a company with thousands of employees, a decade of logistics experience, and an existing delivery network to plug into.
But here is where most PM blogs get lazy. They see the order gap and say Zepto won because it was more focused, or built better infrastructure, or had a cleaner app.
The real picture is more complicated. And more interesting.
Because Swiggy Instamart is not a poorly built product. It has 1,143 dark stores , almost identical to Zepto’s 1,139. It dropped the Swiggy name and launched a standalone app in 2025, directly addressing the identity problem. And its CEO has articulated a clear strategic thesis: compete on differentiation and higher order value, not on speed alone.
So what actually explains the order gap?
That is what this teardown is about.
Product Strategy Steps
Step 1: Derive the JTBD From Observations – Not Assumptions
Framework: Jobs To Be Done
I want to be transparent about how I apply JTBD here. It is not from mission statements or internal documents. The main source of identifying it, is from observation of each product’s decisions i.e. name, infrastructure, positioning, app structure , and worked backwards to the job each company believes it is solving.
This is how JTBD actually works. Clayton Christensen said you identify the job from what the product does, not from what the company says. Actions reveal intent better than any press release.
What I observed about Zepto:
- The name. A zeptosecond is one of the smallest measurable units of time. That is not a branding choice. That is a product thesis embedded in the company name from day one.
- They committed entirely to dedicated dark stores from founding – expensive, operationally complex, and built around one outcome: minimising delivery time.
- Their original tagline was “10 minute delivery.” Not “best prices.” Not “widest selection.” Speed was the entire value proposition.
- Their standalone app opens directly to groceries. No tabs to navigate. No other identity competing for attention.
From these observations, the job Zepto is solving becomes clear: “I need something right now and I cannot wait even 30 minutes.”
What I observed about Instamart:
- Launched inside the Swiggy app in August 2020 – inheriting an identity built entirely around food delivery.
- Swiggy’s positioning has always been about food first. Instamart started as an extension of that identity, not a standalone promise.
- In May 2025, Instamart dropped “Swiggy” from its name and launched a standalone app. That is a significant admission , the inherited identity was creating a constraint.
- Swiggy’s CEO said in May 2026 that the quick commerce market is becoming commoditised, and Instamart’s response is to compete on differentiation -private labels, exclusive brand partnerships, higher average order values , rather than on speed alone.
From these observations, the job Instamart is solving has evolved. Early on it was: “I need groceries and I am already on Swiggy.” Now it is moving toward: “I want a better grocery experience, not just a faster one.”
That is a deliberate strategic choice, not a mistake.
One is competing on speed. One is competing on quality and selection.
Both are legitimate bets. The order gap tells us which bet is winning right now , but it does not tell us which bet will win in three years.
Step 2: Where Does Each Journey Break?
Framework: Trigger → Action → Outcome
Zepto user on mobile app — 2021 to now:
- Trigger: out of milk at 10 PM, needs it now
- Action: opens Zepto, finds milk immediately, two taps to checkout
- Outcome: milk in 12 minutes. Promise kept. Habit formed.
Instamart user on mobile app — early days:
- Trigger: same. Out of milk at 10 PM.
- Action: opens Swiggy — lands on food delivery home screen. Finds Instamart tab. Searches for milk. Checks out.
- Outcome: delivery in 20-30 minutes. Promise: vague.
Instamart user — post rebrand, standalone app, 2025-26:
- Trigger: wants to do a weekly grocery run with quality products
- Action: opens Instamart app. Browses private label “Noice” products alongside branded items. Builds a larger basket.
- Outcome: delivery in 15-20 minutes. Higher order value. Different satisfaction.
This is the important insight. Instamart’s broken box in the early days was Action — the navigation friction of finding groceries inside a food app. They have partially fixed that with the standalone app.
But the Trigger has also shifted. Zepto is optimised for the emergency, low-basket, high-frequency trigger. Instamart is now deliberately targeting the planned, high-basket, quality-conscious trigger.
All have different triggers. Different jobs. Different metrics of success.
Step 3: The Friction Each Product Carries
Framework: MECE Friction Scan
Discovery friction
Zepto: low. You open a grocery app and you are already browsing groceries. The product does one thing and is immediately useful.
Instamart early: medium-high. Opening a food app to buy groceries created a mental mismatch.
Instamart now: low for the standalone app. Medium for users who still access it through Swiggy. Both entry points exist simultaneously, which creates inconsistency.
Input friction
Zepto: low. Fast search, predictive results, 46,000 SKUs organised for speed. Built for someone who knows what they want and wants to add it quickly.
Instamart: medium. The catalogue is large but the experience is evolving toward browsability — which is intentional for a higher-AOV strategy but adds friction for the in-and-out user.
Feedback friction
Zepto: low. Real-time tracking is accurate. Delivery time estimates are reliable. When speed is your promise, a reliable ETA is not a feature — it is the product.
Instamart: medium. Delivery estimates have historically been less reliable. As their strategy shifts toward differentiation over speed, this may matter less. But the transition creates a gap where neither the speed nor the quality positioning is fully clear to users yet.
Step 4: The Decision That Actually Explains the Gap
Framework: Impact vs Effort
Here is where I need to correct something I almost got wrong.
My first instinct was to say Zepto won because it built dark stores and Instamart did not. That is factually incorrect. Instamart has 1,143 dark stores, essentially the same number as Zepto.
The real difference is not infrastructure. It is timing and commitment.
Zepto committed to dark stores as its founding decision in 2021, before quick commerce had proven itself in India. It was an all-in bet on one thesis: speed wins.
Instamart built dark stores too ,but came to the model while also managing an existing food delivery business, an existing brand identity, and an existing user base with different expectations. Every decision was made in the context of a larger platform, not as a pure-play quick commerce product.
That is the real product lesson. Not that Swiggy chose wrong. But that building a new product category inside an existing product is fundamentally harder than building it from scratch.
Zepto had one job. One thesis. One metric. Everything pointed in the same direction.
Instamart had to balance grocery speed with food delivery identity, with cross-selling opportunities, with platform coherence, with investor expectations for a multi-vertical business.
High focus beats managed complexity in the early stages of a new category. Every time.
Step 5: What Metric Actually Matters?
Framework: North Star + Leading Indicator
I want to be honest here , I do not know Zepto’s or Instamart’s official internal North Star metrics. I am deriving this from their stated strategies and public disclosures.
For Zepto, the metric that best explains their growth is orders per day , how many times users trusted the product enough to pay for it, every single day. Their 119.5% CAGR in order volumes between FY2024 and FY2026 is a frequency story, not an acquisition story.
Their likely leading indicator: time between first and second order. If a user comes back within 48 hours of their first order, the habit loop has begun. That is the signal that predicts long-term retention.
For Instamart, the metric that fits their stated strategy is average order value , how much each basket is worth. Their CEO explicitly said they are not competing on discounts. They want higher-quality users who spend more per order, not just more orders.
Their likely leading indicator: repeat purchase rate for private label products. If users who buy their “Noice” private label come back specifically for it, they have built a defensible moat that Zepto cannot easily replicate.
Two different metrics. Two different strategies. Neither is obviously wrong.
What This Actually Means for the PM Interview
When an interviewer asks you to compare Zepto and Swiggy Instamart, most candidates will say: Zepto won because it was more focused.
That is true but incomplete.
The stronger answer acknowledges the full complexity: “Zepto and Instamart are running different strategies, not the same strategy with different execution quality. Zepto is optimising for order frequency — high volume, lower basket, speed-sensitive users. Instamart is deliberately moving toward differentiation — higher basket value, quality-conscious users, private labels. The order gap today tells us Zepto’s bet is winning in the short term. Whether Instamart’s differentiation thesis creates a more defensible business in three years is the more interesting question.”
That answer does three things.
(1) It shows you understand that competitors can have legitimately different strategies , not just better or worse execution.
(2) Shows !! you can read strategy from product decisions — which is JTBD applied correctly.
(3) It shows you can hold complexity without collapsing it into a simple winner-loser narrative.
That is the PM thinking interviewers are actually hiring for.
Before Your Next Interview
When you face a product comparison question, resist the temptation to immediately pick a winner.
First ask: are they solving the same job or different jobs?
If different jobs — the comparison is really about which job is larger, faster-growing, or more defensible. Not which product is better built.
If same job — then execution, friction, and metric discipline determine the winner.
Zepto and Instamart started by solving different jobs. They are now converging — both have dark stores, both have standalone apps, both are competing for the same user at 10 PM who needs milk.
That convergence is where the real battle is. And it is just beginning.
