Why We Built PeyCoIn in India

Most fintech is built in the US, for the US. The assumptions are baked in: credit cards everywhere, reliable broadband, English as the primary language, Venmo for splitting, PayPal for international.

We built PeyCoIn in India. This shaped every major decision we made — not as an afterthought, but as the foundation.

The realization: India doesn't fit the US fintech mold

When we started using Splitwise in India, the product worked great for one thing: tracking who owes what. But everything else was friction.

• Settlement required leaving the app to use PhonePe or Google Pay
• The free tier limited you to 3 expenses per day (absurd for active users)
• No Hindi, no INR-first defaults, no support for common Indian payment patterns
• The app assumed constant internet connectivity — not true on Indian metro rides

These weren't bugs. They were design assumptions built for a different market. We decided to build for ours.

Offline-ready by default

Internet connectivity in India is improving rapidly. But it's still not always there — metro rides, flights, Goa beach trips, remote field trips with friends.

Most expense apps slow down or stop when connectivity drops. PeyCoIn is designed to keep the core flow available even when the network is patchy.

You can add expenses, review balances, and keep moving. When connectivity returns, updates sync quietly in the background.

This isn't just about reliability. It's about making daily expense logging feel fast and dependable every time.

UPI-native from day one

UPI has over 300 million active users in India. It's how people actually send each other money — not bank transfers, not cash apps, not Venmo equivalents.

We built UPI directly into PeyCoIn's settlement flow. The person being paid adds their UPI ID to their profile once. After that, anyone who owes them money can pay from inside PeyCoIn — their UPI app opens pre-filled with the right ID and amount, they confirm, done. No asking for UPI IDs over WhatsApp. No copy-pasting. No app-switching.

PeyCoIn doesn't process the payment — your bank's UPI rails do. We just make sure the right UPI ID is always in the right place.

Ten languages, right-to-left included

India has 22 official languages. We started with 10: English, हिन्दी, Español, Français, Português, Deutsch, Bahasa Indonesia, 日本語, 简体中文, and العربية.

Arabic required full right-to-left support, including mirrored navigation, spacing, and reading flow. We invested in that care because building for the world means building for everyone, not just left-to-right readers.

The 10-language support also reflects our diaspora thesis: Indians abroad share money with friends in multiple currencies, in multiple languages. We want to serve them.

The diaspora opportunity

The Indian diaspora is 18 million people across the US, UK, Middle East, Southeast Asia, Canada, and Australia. They share money with each other across currencies. They send money home. They go on group trips mixing Indian and international friends.

PeyCoIn's multi-currency groups, offline-ready experience, and 10-language support make it uniquely suited for this use case. Multi-currency is a paid feature in most competing apps — PeyCoIn includes it free. No other app has UPI + USD + EUR in the same product at no cost.

What "India-first" actually means

It doesn't mean India-only. It means India-shaped. The constraints we designed for — offline access, UPI, multi-lingual support, high-frequency expense logging — turn out to be useful globally. Offline-ready access is valuable anywhere. Multi-currency is valuable anywhere. Clear, simple design is valuable anywhere.

We're building a global product. We just started by solving India's problems first — because that's where we are, and that's what we understand.

The world's most useful apps were built for a specific context and generalized. We're betting that India is the right specific context for shared finance.
