Zepto Is Building India’s Urban Grocery Supply Chain Around Quick Commerce
Zepto co-founder and CEO Aadit Palicha argues that the company is not mainly a quick-commerce app but a grocery infrastructure business built around dark stores, supply-chain control and the promise of 10-minute delivery. In a Startup School India conversation with Jared Friedman, Palicha traces Zepto’s path from a COVID-era WhatsApp grocery group in Mumbai to a platform handling millions of daily deliveries, saying the decisive moves came from staying close to dissatisfied customers and working backward from speed, quality, selection and price.
Swedish Founders Should Leave for Silicon Valley, Then Return
Paul Graham told Swedish founders in Stockholm that the way to strengthen the city’s startup ecosystem may begin with leaving it. The Y Combinator founder argued that Silicon Valley remains the startup world’s dominant center because it concentrates ambitious peers, fast-moving investors, chance encounters and a culture of help; Stockholm’s opportunity, he said, is for founders to absorb those advantages and return with stronger companies, capital and habits that can compound locally.
Personal AI Lets One Builder Do the Work of Teams
Y Combinator CEO Garry Tan argues that personal AI is reaching a stage comparable to the early personal computer: powerful enough to let one person build software that once required a team, but still brittle enough to demand technical ownership. Drawing on his work with Claude Code, OpenClaw and his GStack workflow, Tan makes the case for heavy token use, Markdown-encoded “skills” and multiple coding agents under one accountable human operator. The larger question, he says, is whether users will control their own AI tools, data and prompts, or work inside opaque systems controlled by others.
Razorpay Turned India’s Payments Friction Into a $180 Billion Platform
In a Startup School India fireside with YC’s Jon Xu, Razorpay co-founder and CEO Harshil Mathur argues that the company’s rise in Indian payments came less from an initial fintech thesis than from staying with a painful customer problem through regulation, bank failures and market skepticism. Mathur says Razorpay turned delays into a moat, customer trust into an operating principle, and early bets such as UPI into openings incumbents missed. His broader case is that founders must keep direct ownership of the decisions that define the company, especially as AI lowers the cost of building and raises the cost of slow judgment.
