On the Blume Podcast, Harshil Mathur and Shashank Kumar sit down with Karthik Reddy to walk through the *raw* Razorpay journey—the rejections, near-dead ends, and scrappy hacks that shaped India’s payments backbone.
You’ll hear stories rarely told elsewhere: how they built coding culture at IIT Roorkee’s SDS Labs (raising money from the college itself and even sneaking in “presentation monitors” to get approvals), how a simple crowdfunding side-project revealed the broken state of India’s online payments, and why they were turned away by ~100 bankers before one “yes” finally came—with a condition of a ₹25 lakh security deposit, funded by Shashank’s grandfather.
Beyond the anecdotes, this is a deep dive into what it takes to build regulated infrastructure in India:
- Why design became Razorpay’s hidden growth engine, turning a backend product into a visible trust signal at checkout.
- Why “move fast and break things” never works in payments, and how availability—not speed—became the non-negotiable cultural value.
- How word-of-mouth and community groups (Facebook, WhatsApp) built their early GTM flywheel when big players ignored small customers.
- Why tech—not sales or distribution—is still their ultimate moat.
If you’ve only heard the polished Razorpay story, this episode offers the unvarnished version: two coders, relentless grit, and the mindset shift from “startup survival” to building an enduring institution.
