Fractional CTO
for Fintech Companies
Technology leadership built on real fintech experience. We have architected payment platforms, built high-availability financial systems, and navigated the regulatory landscape that makes fintech uniquely challenging.
Fintech Needs a Different Kind of CTO
Fintech is not just software with money flowing through it. The intersection of financial regulation, real-time transaction processing, and customer trust creates engineering challenges that generic technology consultants rarely understand. We bring hands-on experience from building and scaling payment platforms, high-availability financial systems, and teams that ship under regulatory scrutiny. Whether you are a pre-Series A payments startup or a growing lending platform, we provide the technology leadership that understands your domain.
Our Fintech Experience
Payment Platform Architecture
Designing systems that process financial transactions demands zero-tolerance for data loss, sub-second latency, and graceful handling of downstream failures. We have hands-on experience architecting payment platforms with idempotent processing, exactly-once semantics, and reconciliation pipelines that catch discrepancies before they become incidents.
High-Availability & Disaster Recovery
When your platform processes money, downtime is not an inconvenience — it is a regulatory event. We design multi-region, active-active architectures with automated failover, comprehensive monitoring, and incident response runbooks that meet the resilience expectations of financial services.
FCA Compliance & Regulatory Engineering
FCA authorisation, PSD2, Strong Customer Authentication, GDPR, anti-money laundering — the regulatory landscape shapes every architectural decision. We help fintechs build compliance into the platform from day one rather than retrofitting it as an afterthought, reducing both risk and the cost of future audits.
Security-First Engineering
Financial data demands defence in depth: encryption at rest and in transit, key management, tokenisation, PCI DSS alignment, and security testing embedded in CI/CD. We establish security practices that satisfy auditors without paralysing your engineering velocity.
How We Help Fintech Companies
Pre-Series A Startups
You have a working product and early traction but need senior technology leadership to professionalise the architecture, prepare for scale, and present credibly to investors. A fractional CTO gives you that expertise without the burn rate of a full-time C-level hire.
Growth-Stage Platforms
Transaction volumes are climbing, the team is growing, and the early-stage architecture is showing strain. We help scale the platform, restructure the team, and establish the engineering practices needed for the next phase — without a risky platform rewrite.
Legacy Fintech Modernisation
Established financial services firms with aging technology that needs to compete with agile challengers. We modernise incrementally using the strangler pattern — keeping existing systems running while gradually replacing them with modern, cloud-native components.
Investor Due Diligence
Investing in a fintech? We provide independent technical due diligence with domain-specific insight — assessing not just code quality but regulatory compliance, security posture, and whether the platform can handle the growth the business plan assumes.
Technology Stack Expertise
We are polyglot engineers who choose the right tool for the job. In fintech, that typically means:
- ✔ Backend: Golang (high-throughput transaction processing), Python, C#, modern JavaScript
- ✔ Infrastructure: AWS (ECS, Lambda, RDS, SQS) and Azure (AKS, Functions, SQL Database)
- ✔ Data: PostgreSQL, Redis, event-driven architectures, real-time streaming
- ✔ Security: PCI DSS alignment, encryption, tokenisation, key management
- ✔ Practices: Domain-driven design, microservices, CI/CD, infrastructure-as-code
