Y CombinatorZepto: How Two 17-Year-Olds Built India's Largest Seller Of Fruits and Vegetables
CHAPTERS
First-principles customer delight as the founding philosophy
Aadit frames Zepto’s approach as starting from the most extreme possible customer experience and working backward to make it real. This principle becomes the through-line for later decisions like dark stores and 10-minute delivery.
From teenage builders to a COVID WhatsApp grocery service
Aadit and his cofounder Kewal began at 17 during COVID, not aiming to build a company but to solve a local problem in Mumbai. The first product was a neighborhood WhatsApp group that delivered groceries when regular channels broke down.
The Stanford decision: delaying the leap until early PMF signals
Aadit explains the choice between going to Stanford and pursuing the startup, emphasizing a tactical approach rather than a heroic leap. They took time to find early product-market fit indicators before fully committing.
Launching into a crowded market by listening to dissatisfied customers
Despite existing large grocery delivery players in India, Aadit believed customers still weren’t satisfied. By speaking directly with users, they identified the core dimensions that mattered—speed, quality, selection, and price.
The pivot: controlling the experience with dark stores (starting in an apartment)
Zepto emerged when they realized store-to-doorstep fulfillment gave them little control over delivery time and quality. They experimented with holding inventory themselves—first in the cofounder’s apartment—then scaled to proper dark stores as demand spiked.
Why 10-minute delivery was the bet: working backward from the extreme
Aadit contrasts building from financial/supply constraints with designing for maximum customer value. He argues that extreme speed created unexpectedly high demand, which then improved unit economics through higher throughput.
Iterating fast and obsessing over the first 100 customers
The company’s early progress came from experimentation, frequent failure, and tight feedback loops. With little outside noise during COVID, Aadit and Kewal focused intensely on a small user set until they found a model people truly loved.
Zepto’s hidden engine: logistics, operations, and supply chain depth
Aadit emphasizes Zepto is fundamentally a daily-needs retail and logistics company, not just an app. Delivering in minutes requires countless operational decisions inside dark stores and a sophisticated upstream supply chain.
Fruits & vegetables at national scale: sourcing directly from farmers
Zepto built one of India’s largest fruits-and-vegetables supply chains, sourcing massive volume from across the country. This capability strengthens freshness and reliability—key to grocery trust and repeat usage.
What Zepto is today: massive usage, new revenue streams, still “day one”
Aadit shares the scale of Zepto’s growth—millions of daily deliveries and a huge customer base—while noting the market remains far from fully penetrated. He also highlights the rapid rise of an advertising business inside the app.
Long-term vision: India’s urban grocery infrastructure and hyperlocal e-commerce platform
Zepto aims to become foundational grocery infrastructure across top Indian cities, organizing an historically fragmented supply chain. Aadit suggests cracking hyperlocal commerce could create an India-native platform comparable in impact to major global e-commerce players.
How Zepto uses AI: forecasting, ads optimization, and internal automation
AI is applied across supply chain and consumer surfaces to improve speed, accuracy, and profitability. Aadit describes ML-based forecasting replacing manual work, AI-led ad tooling boosting ROAS for brands, and automation reducing software spend and headcount needs.
Engineering and data org: team size, capabilities, and hiring
Aadit outlines the technical organization supporting Zepto’s operational complexity. The company employs hundreds of engineers plus substantial data/product/design capacity and continues to hire aggressively.
How Aadit leveled up as a founder: learning via elite teams and shameless questions
Aadit attributes rapid personal growth to surrounding himself with experienced leaders who joined early and pushing himself to learn from them daily. He stresses humility—asking basic questions and absorbing expertise across functions.
