Launching a Niche Neobank MVP for Millennial Investors
Industry: FinTech, Investment
Client Overview: A well-funded startup aimed to launch a neobank specifically for millennials, combining standard banking features with micro-investment opportunities in ESG-focused portfolios. They needed a partner who could build a secure, compliant MVP quickly to secure their next funding round.
"CIS was more than a vendor; they were a true technical co-founder. Their speed, expertise in FinTech APIs, and proactive guidance on security were instrumental in our successful launch. We hit our user acquisition goals a month ahead of schedule."
- Alex Royce, Founder, InvestSphere
The Problem
The client had a strong vision but lacked the in-house technical team to execute it. They needed to build a fully functional mobile app for iOS and Android, integrate with multiple third-party services (KYC, card issuing, brokerage API), and ensure the architecture was scalable from day one, all within a tight 6-month timeline.
Key Challenges
- Aggressive 6-month timeline to MVP launch.
- Complex integration with four different financial APIs.
- Ensuring bank-grade security and data privacy from scratch.
- Building a scalable cloud infrastructure on a startup budget.
Positive Outcomes
Modernizing a Regional Credit Union's Mobile Banking Platform
Industry: Banking, Financial Services
Client Overview: A regional credit union with over 50,000 members was struggling with an outdated, clunky mobile app that was causing member dissatisfaction and falling behind competitors. They needed a complete overhaul to deliver a modern, intuitive, and feature-rich mobile experience.
"The transformation has been incredible. CIS's team seamlessly integrated with our legacy core banking system while delivering a user experience that rivals the top neobanks. Our app store ratings have jumped from 2.1 to 4.8 stars."
- Jenna Clay, VP of Digital Strategy, Unity Credit Union
The Problem
The existing app was slow, prone to crashing, and lacked essential features like mobile check deposit and biometric login. The challenge was to build new native apps from the ground up while ensuring a secure and reliable integration with their 20-year-old core banking system, which had limited and poorly documented APIs.
Key Challenges
- Integrating with a legacy core banking system.
- Migrating existing users to the new platform without disruption.
- Meeting strict accessibility (WCAG) compliance standards.
- Implementing modern security features like biometrics.
Positive Outcomes
Building a Secure Embedded Finance (BaaS) Platform
Industry: Logistics, E-commerce
Client Overview: A large logistics platform wanted to offer financial services directly to its network of thousands of freelance drivers. The goal was to provide them with dedicated business accounts, instant payouts after each delivery, and a company card for fuel and expenses, thereby increasing driver loyalty and creating a new revenue stream.
"CIS delivered a robust and highly secure BaaS platform that has become a key differentiator for us. Their expertise in microservices architecture and API security gave us the confidence to handle millions of transactions. It's a game-changer for our driver retention."
- Marcus Dyer, CTO, FreightFlow Logistics
The Problem
The client needed to build a Banking-as-a-Service (BaaS) layer that could integrate with a partner bank and their existing logistics platform. The system had to be highly reliable, capable of processing thousands of real-time payments simultaneously, and expose secure APIs for their main application to consume.
Key Challenges
- Designing a highly available, fault-tolerant microservices architecture.
- Building secure, well-documented APIs for internal consumption.
- Ensuring real-time payment processing with zero downtime.
- Navigating the three-way compliance between them, the partner bank, and regulators.

Frequently Asked Questions
The cost varies significantly based on complexity. A Minimum Viable Product (MVP) with core features for one platform (iOS or Android) typically ranges from $60,000 to $150,000. A full-featured, multi-platform application with advanced AI, multi-currency support, and extensive third-party integrations can cost $300,000 or more. Our interactive calculator can give you a more tailored preliminary estimate.
An MVP can typically be designed, developed, and launched within 4 to 6 months. A more complex, full-featured application can take 9 to 12 months or longer. Our AI-accelerated development processes and dedicated pod model are designed to optimize this timeline without compromising on quality or security.
Security is our top priority. We are SOC 2 and ISO 27001 certified. Our process includes: secure coding practices (OWASP Top 10), end-to-end encryption, secure cloud architecture on AWS/Azure, regular penetration testing, and adherence to regulations like PCI DSS and GDPR. We build compliance and security into the foundation of your app.
Not necessarily. Many neobanks start by partnering with a licensed bank through a Banking-as-a-Service (BaaS) provider. This allows you to offer FDIC/FSCS-insured accounts and other regulated services under their license, significantly reducing your initial regulatory burden and time-to-market. We have experience integrating with various BaaS platforms.
We offer comprehensive and flexible support plans to ensure your platform's long-term success. This includes 24/7 server monitoring and incident response, regular maintenance and updates, bug fixes, and dedicated support for developing new features and enhancements based on user feedback and your evolving business strategy.
