The Challenge
JAR's founder came to us with a vision: create a secure payment integration platform specifically designed for the UK market. The fintech space is notoriously complex, with strict regulatory requirements, security concerns, and the need for seamless integration with existing banking infrastructure.
🎯 Key Challenges
- Complex financial workflows with multi-currency support
- Strict UK regulatory compliance (FCA, GDPR)
- Bank-level security requirements
- Integration with multiple payment processors
- Limited initial budget—needed equity partnership
Our Approach
We partnered with JAR through an equity arrangement, becoming true technical co-founders rather than just service providers. This meant we were equally invested in the platform's success.
Phase 1: Discovery & Architecture
We spent the first month understanding the regulatory landscape, mapping out user journeys, and designing a scalable architecture that could handle millions of transactions.
Phase 2: Core Platform Development
Built the foundation—secure authentication, payment processing engine, and the core API that would power all integrations.
Phase 3: Compliance & Security
Implemented bank-grade security measures, PCI DSS compliance protocols, and GDPR-compliant data handling.
Phase 4: Integration & Testing
Connected with payment processors, conducted extensive security audits, and ran beta testing with real transactions.

Key Learnings
1. Start with Compliance
In fintech, compliance isn't an afterthought—it's foundational. We baked regulatory requirements into the architecture from day one, saving months of refactoring later.
2. Equity Alignment Matters
When both parties have skin in the game, decision-making becomes collaborative rather than transactional. We made better technical decisions because we cared about long-term success, not just project completion.
3. Security is a Feature
For fintech, security isn't overhead—it's a competitive advantage. The investment in security measures became a key selling point with enterprise clients.
