Simple Wallet

The infrastructure play that is rewriting self-custody at scale

When you have 2 million users waiting for a product, speed is not a luxury, it's survival. Simple Wallet needed card infrastructure built for millions of transactions while preserving complete self-custody. They needed it yesterday. Wirex BaaS delivered.

2 Million Users. Zero Infrastructure. One Solution.

Simple Wallet was not starting from scratch, they were sitting on a goldmine. Over 2 million installs. Tens of thousands of active users. A community of creators, freelancers, and digital professionals all earning in crypto, all waiting for one thing: a way to actually spend it.

The problem? Building card infrastructure from scratch takes years. Licensing alone could eat 18-24 months. Direct Visa relationships? Even longer. Every week of delay was users lost to competitors.

"Building this infrastructure independently would likely have taken a couple of years. Wirex BaaS collapsed that timeline into weeks."

Wirex BaaS changed the equation. What should have taken years took weeks. Simple Wallet went from zero card infrastructure to a fully operational, compliant card program capable of serving their entire 2M+ user base, without compromising their self-custody architecture.

The result? Immediate traction. Explosive demand. And a clear path to scale into the millions.

The Scale Opportunity

Simple Wallet is not a startup hoping for users, they already have them:

  • 2 million+ app installs and growing
  • Tens of thousands of active users transacting regularly
  • Strong demand signals across European markets
  • Expansion pipeline into Latin America and Southeast Asia
  • AI-agent layer in development to drive next-gen engagement

The User Base

These aren't speculators. They're professionals:

  • Creators monetizing content globally. Streamers receiving international payments.
  • Freelancers billing in crypto. Remote workers managing multi-currency income.
  • Entrepreneurs running borderless businesses.

For them, crypto is income, not investment. And income needs infrastructure.

"Our mission is to make crypto a practical financial tool for everyday use. With 2 million users waiting, we needed infrastructure that could match our ambition."

The Challenge: 2 Million+ Users, Zero Card Infrastructure

Simple Wallet faced the classic scale-up dilemma: massive demand, missing infrastructure. Their 2 million users were ready. The card rails were not.

Building in-house was not an option. Not at the speed required. Not with users waiting.

The Timeline Problem

Traditional Build PathWirex BaaS Path
2-4 YearsWeeks
Licensing: 12-24 months✓ Already licensed
Visa partnership: 18-36 months✓ Principal member
Infrastructure: 12-18 months✓ Ready to deploy
Testing and compliance: 6-12 months✓ Battle-tested

That's not an optimization. That's a complete rewrite of what's possible.

The Self-Custody Constraint

Most BaaS providers require custody. They want to hold funds. Control wallets. Manage assets. That breaks Simple Wallet's entire model, and their promise to 2 million users.
