The Developer-First Revolution
How two IIT graduates transformed Indian fintech by putting developers—not businesses—at the center of payment infrastructure.
"We built the payment infrastructure developers wish existed when they started coding."
In 2014, integrating online payments in India meant navigating a labyrinth of bureaucracy, mediocre documentation, and APIs that seemed designed to frustrate developers. Two IIT Roorkee graduates—Harshil Mathur and Shashank Kumar—decided this was unacceptable.
Today, Razorpay processes $90+ billion annually, serves 10 million businesses, and is valued at $7.5 billion[3]. Their secret? An obsessive focus on developer experience that made payments feel less like infrastructure and more like magic.
The Problem: Payment Integration Hell
Before Razorpay, Indian developers faced a nightmare:
1. Arcane Integration Process
Payment gateway integrations took 2-3 weeks of engineering time. Documentation was scattered across PDFs, PHP code samples were outdated, and support tickets went unanswered for days.
2. Hostile to Modern Tech Stacks
Most gateways offered Java/.NET SDKs but ignored Ruby, Python, Node.js—the languages startups actually used. Developers had to write custom wrappers from scratch.
3. Compliance Bureaucracy
Getting a merchant account required physical paperwork, bank visits, and 2-3 month approval cycles. Startups couldn't afford to wait.
4. No Testing Environment
Want to test your payment flow? Most gateways required you to make real transactions and refund them. Test mode? What's that?
Harshil and Shashank experienced this frustration firsthand while building their previous startup. They knew there had to be a better way.
The Journey: Timeline & Pivots
Y Combinator W15 Batch
Razorpay accepted into Y Combinator with the pitch: "Stripe for India." The team moves to San Francisco for 3 months, learns Silicon Valley's obsession with developer experience.
Launch: 10-Minute Integration
Razorpay goes live with a radical promise—integrate payments in 10 minutes with just 3 lines of code. First 100 merchants onboarded within a month, all through word-of-mouth.
Seed Round: $1.25M from Sequoia
Sequoia India leads seed round after seeing 15% week-over-week growth. Key metric: 92% of developers complete integration on first try (industry average: 40%).
Crisis: Demonetization Shock
India's cash ban overnight. Digital payments surge 300% but infrastructure collapses. Razorpay's uptime: 99.7% while competitors crash. Trust is earned in chaos.
Pivot: UPI Integration Sprint
Team builds UPI support in 3 weeks (competitors took 6 months). Razorpay becomes the first gateway to support UPI, Paytm, wallets, cards, and netbanking—all in one API.
Series C: $75M at $300M Valuation
Tiger Global and Sequoia lead round. Processing $10B annually. Key insight: 70% of growth came from developer referrals, not sales.
Product Expansion: RazorpayX
Launch business banking suite (RazorpayX). Strategy shift: Don't just process payments—own the entire money stack for startups.
Series E: $160M Amid Pandemic
Raises at $3B valuation during COVID. E-commerce boom drives 5x growth. Now processing $50B annually with 5M merchants.
Unicorn Status: $7.5B Valuation
Series F ($375M) from Lone Pine, Alkeon, TCV. Razorpay becomes India's 18th unicorn. Processing $90B/year, 10M businesses, 1,800 employees.
Present Day: Fintech Ecosystem
Razorpay now offers payments, banking, lending, payroll, and corporate cards. Revenue run-rate: $500M+. IPO planned for 2025.
The Numbers That Matter
10 years of developer-first growth
From Payment Gateway to Fintech Ecosystem
Before
Payment Gateway (Single Product)
Revenue capped by transaction fees (1.5-2%). Commoditization risk as competitors launch. Customer acquisition cost rising.
ARR: $40M, Gross Margin: 45%, CAC: $800
After
Full-Stack Fintech Platform (Payment + Banking + Lending + Payroll)
Launch RazorpayX (business banking), Capital (lending), Payroll (salary disbursement). Cross-sell to existing merchant base. Higher LTV, stickier customers.
ARR: $500M+, Gross Margin: 65%, LTV:CAC: 12:1
By 2024, non-payment products contribute 40% of revenue. Average customer spends 4.2x more when using 2+ products. Churn reduced from 12% to 3% annually.
The Developer-First Playbook
Razorpay's growth wasn't driven by sales teams or marketing budgets. It was fueled by developers who became evangelists because the product just worked.
1. Documentation as a Product
Razorpay treated docs like a SaaS product[4]. Every API endpoint had:
- •Live code examples in 8 languages (Python, Ruby, Node.js, PHP, Java, .NET, Go, React)
- •Interactive API explorer with real test keys
- •Video tutorials for common use cases
- •Stack Overflow-style community forum with <1 hour response time
2. Test Mode That Actually Works
Test keys worked identically to live keys—no surprises in production. Razorpay even built a "simulate payments" feature where developers could trigger success, failure, and timeout scenarios without touching real money. Competitors didn't have this until 2018.
3. Instant Activation (No Paperwork)
Razorpay's killer innovation: instant test account activation. Developers could start building immediately. KYC verification happened afteryou decided to go live. This reduced time-to-first-integration from 3 months to 10 minutes.
Industry secret: 60% of merchants who start integration never finish (friction kills). Razorpay's completion rate: 92%.
4. Webhooks, Not Polling
Instead of forcing developers to poll for payment status (wasteful, slow), Razorpay sent real-time webhooks. Developers loved this—it meant faster checkout flows and happier customers. Competitors added webhooks 2 years later.
5. Localization at the API Level
Razorpay didn't just support Indian payment methods—it made them first-class citizens. UPI, Paytm, PhonePe, wallets, EMI, cardless credit—all accessible through the same unified API.
Technical insight: While Stripe added India support as an afterthought, Razorpay designed every feature for India first, then expanded internationally.
Team & Culture
"We don't hire salespeople for the first 50 customers. If your product needs a sales pitch, it's not good enough. Developers don't buy—they choose. The product has to sell itself."
Core Cultural Principles
Developers are our customers, not businesses. Build for the person writing code at 2 AM, not the VP signing contracts.
Uptime is non-negotiable. 99.99% isn't good enough when you're processing payroll and rent payments.
Speed compounds. 10-minute integration today becomes 10 million merchants tomorrow through word-of-mouth.
Documentation is marketing. If your docs are better than competitors' products, you've already won.
Localization is strategy, not translation. UPI isn't "India's Venmo"—it's a fundamentally different paradigm.
Hire for curiosity, not credentials. Some of our best engineers are self-taught. IIT tag doesn't guarantee product thinking.
Lessons for Founders
Strategic insights you can apply to your own startup journey.
Developer Experience is a Moat
In B2B SaaS, switching costs are psychological, not technical. Once developers love your API, they'll defend it in every architecture review. Razorpay didn't just build a payment gateway—they built a developer community that became their sales force.
When Razorpay had a 15-minute outage in 2019, developers on Twitter defended them and compared uptime to competitors. That's brand loyalty money can't buy.
Localization is Not Translation
Indian fintech isn't "US fintech with rupees." UPI, cash-on-delivery, NEFT, IMPS, wallets—these are unique to India's digital ecosystem. Razorpay won because they understood local payment psychology: Indians don't trust credit cards (2% penetration), but they'll use UPI 20 times a day.
When COVID hit, Razorpay had UPI autopay ready (for subscriptions). Stripe India still doesn't support it natively in 2024.
Expand Horizontal, Not Just Vertical
Payment gateways are low-margin commodities (1.5% transaction fees). Razorpay's genius: use payments as the entry wedge, then cross-sell banking, lending, payroll, and cards. Now they capture 10x more revenue per customer.
A SaaS startup might pay ₹20K/month in payment fees. But with RazorpayX banking + Payroll + Capital lending, that same customer pays ₹2L/month. Same customer, 10x revenue.
Crises Reveal Character (and Uptime)
The 2016 demonetization crisis was existential for Indian fintech. Competitors crashed; Razorpay stayed up. Merchants remembered. Trust built during chaos lasts decades.
Post-demonetization, Razorpay saw 5,000 new merchant signups per day (vs 500 before). Competitors took 6 months to recover market share.
Documentation Compounds
Great docs reduce support tickets, speed up integration, and create advocates. Razorpay's docs are so good that developers screenshot them as examples of "how to write API docs." That's free marketing disguised as customer service.
Razorpay's interactive API explorer is used 2M+ times per month. It's the most visited page after pricing. Docs ARE product.

What You Can Steal for Your Startup
You don't need to be a fintech company to apply Razorpay's lessons:
1. Obsess Over Time-to-First-Value
Razorpay measured "minutes to first successful test transaction." What's your equivalent? Can users experience value in <10 minutes? If not, simplify ruthlessly.
2. Build for the End User, Not the Budget Holder
Razorpay sold to CTOs by delighting junior developers. Bottom-up adoption is slower but stickier than top-down sales. Engineers who choose your product will fight to keep it.
3. Localization is Your Competitive Advantage
If you're building in India (or any emerging market), don't copy Silicon Valley. Understand local infrastructure, payment habits, compliance, and user psychology. That context becomes your moat.
4. Expand Product, Not Just Customers
Once you own a wedge (payments), expand horizontally (banking, lending, payroll). It's 10x cheaper to upsell existing customers than acquire new ones. Razorpay's CAC for RazorpayX: $50 (vs $800 for new payment customers).
