The problem we set out to solve
Consumers today manage money across a fragmented stack of apps, one for payments, another for loans, another for investing, none of which talk to each other. That fragmentation makes it hard to see a complete financial picture, slows every decision, and leaves users juggling multiple logins, providers, and trust relationships. Building a genuine super-app that consolidates these functions demands bank-grade security, regulatory alignment, and open-banking connectivity that most standalone fintechs cannot muster on their own. It also has to scale to a broad user base without sacrificing reliability. The task was to unify payments, lending, and investing in one platform with the backing and rigor of an established bank.
How we built it
Open-banking foundation
We built the platform on open-banking APIs so accounts, payments, and financial data connect securely across providers.
Three products, one app
Payments, lending, and investment modules were designed to share a single identity, wallet, and user experience.
Bank-grade security and compliance
Backed by JS Bank, the platform was engineered to meet banking security and regulatory expectations end to end.
Cloud-native scalability
A Node.js and PostgreSQL stack orchestrated with Kubernetes on AWS delivers reliability at consumer scale.
Key capabilities
Unified payments
Send, receive, and manage payments within a single financial app.
Integrated lending
Access and manage lending products without leaving the platform.
In-app investing
Investment products sit alongside payments and lending in one place.
Open-banking connectivity
Standardized APIs securely link accounts and third-party providers.
Bank-backed trust
JS Bank backing brings institutional security and credibility.
Cross-platform mobile app
A React Native app delivers the full experience on iOS and Android.
Outcomes that moved the needle
Marksystems.io brings payments, lending, and investing into a single, bank-backed super-app built on open-banking APIs. By consolidating three financial products into one platform with JS Bank's backing, it gives users a unified, trusted place to manage their entire financial life instead of scattering it across disconnected apps.
