Real Success Stories in FinTech
We don't just talk the talk. We've helped numerous clients launch successful financial applications. Here's a look at our impact.
MVP for "PayFlow," a B2B Payments Startup
Industry: FinTech (B2B Payments)
"CIS delivered our MVP in just 4 months, which was instrumental in our successful Series A funding round. Their speed, expertise, and transparent communication were exactly what we needed as an early-stage startup."
- Alex Royce, CEO, PayFlowThe Problem
PayFlow needed to build a secure, functional MVP to demonstrate their innovative B2B payment processing concept to investors and early customers. They had a tight deadline and needed a partner who could move fast without sacrificing quality or security.
Key Challenges
- Aggressive 4-month timeline to a functional MVP.
- Requirement for bank-grade security from day one.
- Integration with multiple third-party payment rails.
- Building a scalable architecture for future growth.
Our Solution
We deployed a dedicated "AI-Enabled Growth POD" to accelerate development. Our solution focused on:
- Core Transaction Engine: Built a robust microservices-based backend to handle payment processing.
- Rapid Prototyping: Used Figma to quickly iterate on UI/UX, getting founder feedback in real-time.
- Secure API Layer: Developed a secure API gateway for integrating with banking partners and third-party services.
- Cloud-Native Deployment: Utilized AWS serverless architecture to ensure scalability and cost-efficiency from the start.
Digital Transformation for "Community First Credit Union"
Industry: Banking / Financial Services
"CIS helped us bridge the gap between our traditional services and the digital expectations of our members. Their team seamlessly integrated with our legacy core system, and the new mobile app has been a game-changer for member engagement."
- Jenna Raynor, VP of Digital Strategy, Community FirstThe Problem
Community First was losing younger members to digital-first challenger banks. Their existing mobile app was outdated, slow, and lacked modern features. They needed a complete overhaul that would integrate with their decades-old core banking system.
Key Challenges
- Complex integration with a legacy core banking platform.
- Migrating user data securely with zero downtime.
- Meeting strict NCUA compliance and security standards.
- Designing an intuitive experience for a diverse member base.
Our Solution
Our approach centered on a secure middleware layer to act as a bridge between the old and the new:
- Integration Gateway: We built a secure middleware application to translate requests between the modern mobile app and the legacy core system's APIs.
- Modern Mobile Apps: Developed native iOS and Android applications with features like mobile check deposit, PFM tools, and biometric login.
- DevSecOps Pipeline: Implemented a CI/CD pipeline with automated security scanning to ensure continuous compliance.
- Phased Rollout: Executed a carefully planned, phased rollout to members to gather feedback and ensure a smooth transition.
Enterprise Payment Gateway for "Global Retail Corp"
Industry: Retail & E-commerce
"We needed a highly scalable and reliable payment gateway to process millions of transactions daily across multiple countries. CIS's team demonstrated exceptional expertise in high-volume transaction systems and delivered a platform that exceeded our performance and security requirements."
- Michael Harper, CTO, Global Retail CorpThe Problem
Global Retail Corp's existing payment processing system was a patchwork of third-party solutions that was becoming unreliable and expensive at scale. They needed a unified, in-house payment gateway to reduce costs and improve performance.
Key Challenges
- Handling over 1 million transactions per day.
- Ensuring sub-second transaction processing times.
- Achieving Level 1 PCI DSS compliance.
- Integrating with dozens of international acquiring banks.
Our Solution
We architected and built a high-throughput, fault-tolerant payment gateway from the ground up:
- Event-Driven Architecture: Used a distributed, event-driven architecture on Kubernetes to ensure high availability and horizontal scalability.
- Tokenization Vault: Built a proprietary, PCI-compliant tokenization system to securely store cardholder data.

Frequently Asked Questions
Have questions? We have answers. Here are some of the most common inquiries we receive about neobank app development.
The timeline varies based on complexity. A Minimum Viable Product (MVP) with core features can typically be launched in 4-6 months. A full-featured application with advanced AI and multi-currency support can take 9-12 months or more. Our agile process ensures we deliver value incrementally and get you to market faster.
The three biggest challenges are: 1) **Security:** Ensuring bank-grade security and protecting user data is paramount. 2) **Compliance:** Navigating the complex web of financial regulations (KYC, AML, PCI DSS) is non-negotiable. 3) **Scalability:** Architecting the platform to handle millions of users and transactions without performance degradation is critical for long-term success.
We follow a DevSecOps approach, integrating security into every stage of development. This includes end-to-end data encryption, secure coding practices (OWASP Top 10), regular penetration testing, and building on a secure cloud infrastructure. Our ISO 27001 and SOC 2 certifications validate our commitment to robust security controls.
Not necessarily. Many neobanks start by partnering with a licensed bank (Banking-as-a-Service or BaaS provider) that handles the regulatory aspects and holds the customer funds. This significantly lowers the barrier to entry. We can help you integrate with leading BaaS providers as part of our development process.
Absolutely. We specialize in complex integrations. We can build a secure middleware layer that allows your new, modern mobile application to communicate seamlessly with your existing legacy core banking systems, preserving your investment while delivering a world-class user experience.
Our partnership extends well beyond launch. We offer comprehensive support and maintenance packages that include 24/7 application monitoring, regular security updates, performance optimization, and ongoing development for new features and enhancements to keep your platform competitive.
Don't Just Compete. Redefine Banking.
The opportunity to disrupt the financial industry is now. Partner with a team that has the technical expertise, process maturity, and strategic vision to make it happen. Let's build your neobank.
