Zuper Superannuation Platform

Zuper was a disruptive fintech player on a mission to transform how people manage their superannuation. Backed by a bold vision and a modern UI, they needed the technology infrastructure to match, one that could deliver performance, privacy, and full compliance from day one.

Cypha partnered with Zuper to develop the backend of a secure, modern superannuation platform. Built from the ground up using .NET Core, the solution integrated with ATO and OneVue systems, protected sensitive data, and enabled seamless user control, all within strict financial compliance.

The Challenge

Building a next-gen superannuation platform comes with serious complexity:

  • Integrating with evolving third-party APIs (ATO, OneVue) with incomplete or inconsistent documentation
  • Enabling encrypted data flows and document delivery for financial compliance (e.g. tax reports, statements)
  • Maintaining high performance and uptime across a microservice environment
  • Securing personal information to meet rigorous standards across authentication, storage and data transfer

The Solution

We engineered the technical backbone of the Zuper platform with security, scalability and efficiency at its core.

1. Discovery & Technical Spec
We conducted a deep technical review of the platform architecture and third-party API documentation. Our spec outlined the integration points, security layers and an agile development roadmap.

2. API Architecture & Integration
Using .NET Core, we built a suite of lightweight, modular APIs, streamlining performance by eliminating redundant reference entities. These APIs power the entire Zuper user experience, enabling super fund lookups, updates, and automated transactions.

Key integrations included:

  • ATO for super account verification
  • OneVue for account data and transaction history
  • Internal services for document scheduling and report generation

3. Security by Design
Data security was non-negotiable. We implemented:

  • JWT token-based authentication
  • Encrypted report generation and delivery via SFTP
  • IP whitelisting and rate limiting on critical endpoints
  • Secure storage and retrieval systems for financial documents

4. Ongoing Support & Liaison
We provided monthly triage support, system monitoring, and direct collaboration with OneVue to ensure seamless platform operation, especially during key reporting periods.
