About the client

Our FinTech client introduced the first digital-only banking services to the German market. Their solutions span Banking as a Service, Payments as a Service, SaaS banking platform, and FinTech mobile payment services. Setting the FinTech standard for next-generation banking, our client has developed a transparent, community-focused API and a unique banking platform.

Along with traditional online banking services, our client provides many innovative features including crowdfunding, social landing, multi-currency eWallets, cryptocurrency trading (Bitcoin, Litecoin, Ethereum, Dash, and other altcoins), direct money transfers to Facebook friends list and phone contacts, as well as contactless smartphone payments. Investors are even able to store virtual currency as securely as precious metals and cash.

Custom FinTech Services for Digital Banking

Our client came with the challenge

As the first provider of digital banking services in Germany, our client has a rapidly growing customer base. They’ve developed a large online community of users who receive financial rewards for evaluating new financial products and services. Today, this community has over half a million registered participants, who use the client’s payment services, and every fifth is a full-service client of the digital banking platform.

Thanks to the easy integration of accounts with Facebook, Twitter, eBay, Xing, and other business and social networks, demand for our client’s services is growing exponentially. The bank provides round-the-clock support for its users through online chat and forums without owning any physical offices.

To meet increased demand for custom solutions from their end clients’ businesses, our client needed to extend their Ruby development team to meet growing engineering needs. That’s when they contacted Intellias about establishing dedicated delivery teams to work on several end customer related products.

Intellias provided financial technology services

Within the first four months of our partnership, Intellias established three dedicated teams to provide FinTech development services to our client. We started working on three projects to customize the banking platform and get the most out of existing solutions for end customers.

Our first team is now developing a backend component for the online and mobile FinTech digital banking system. This system will let clients withdraw cash and replenish card accounts at supermarket cash desks, make contactless NFC payments with mobile phones, and use cards abroad. It will also guarantee the safety of online purchases.

Our second team is working on a web solution for one of our client’s partners, a global mobile operator, to extend its web presence and complement an existing application with a new web API.

Our third team is creating a data platform that allows end customers to effectively aggregate and store a great volume of data from many sources, then rapidly process it for future customization of services.

We’re achieving great results together with our FinTech client

Right now, our cooperation is stepping into an active engineering phase of FinTech software development services. So far, both our client’s in-house engineers and our client’s end customers have successfully transferred knowledge to our dedicated teams. This collected knowledge is a prerequisite for developing successful user-centric SaaS solutions for online banking, mobile banking, and payments. The Intellias team has delivered best-in-class FinTech software engineering talent to meet our client’s development needs, diversify their product portfolio, and empower third-party platforms with valuable features.
