Introduction
Fundment is a modern UK-based investment advisory platform serving financial advisers and wealth managers. With rapid customer growth and increasing regulatory obligations, the team needed to secure and scale the platform’s core services without impacting performance. They partnered with Aegasis Labs to deliver a modular architecture, secure and scalable APIs, and redesign of their backend system to support their growth.
Aegasis Labs partnered up to strengthen the scalability, reliability, and compliance posture of their core backend, so the platform could support rapid growth without compromising governance or customer experience.
Fundment was looking for a cloud-native partner to deliver a modular architecture and secure and scalable APIs. They were also looking to get their internal team trained to design modular systems that support long term maintainability.
Based on our expertise in building Cloud Application and AI solutions, we partnered with Fundment to build their advanced backend system using the latest technologies.
What did we do
- Secure, scalable API layer powering core financial and compliance operations with predictable performance under load.
- Build a modular backend that can scale with new products and customers
- Orchestration of complex workflows related to financial transactions and regulatory processes.
- Automated testing and validation pipelines (CI) to ensure faster iteration cycles.
- Compliance friendly design: role-based access, consistent validation, and traceable execution for audits.
- Technical Team mentoring, providing best practices on clean code and version control, to build sustainable systems.
- Improve reliability and auditability across financial workflows
The Story of Fundment
Fundment is a modern, UK-based investment advisory platform, built for financial advisors to manage their clients and their portfolio. As the company grew, their priority was clear: scale quickly without ever compromising the security and compliance their business depends on. They wanted a rock-solid backend that could support core financial operations today and keep pace with tomorrow’s growth.
To get there, Fundment looked for a partner who could strengthen their technical foundations secure, scalable APIs, automated testing so releases stayed safe, and reliable orchestration for complex regulatory workflows. They also wanted their internal teams to adopt best-practice engineering habits so the platform would remain easy to evolve and maintain.
The Opportunity
Wealth Management platforms have to go through intense regulatory scrutiny, while expectations for clients keep increasing. Legacy systems often fragment onboarding, transactions, and reporting that create operational risk and make it hard to be auditable.
As Fundment’s customer base increased, so did the complexity of it’s operations and compliance requirements. The team needed to support more concurrent activity across onboarding, transactions, and reporting without service degradation.
The current manual testing method slowed the addition of new features, and increased iteration cycles which complicated their internal development process. They wanted to ensure the backend architecture was modular, supported adding new features while remaining maintainable for the internal engineering team.
This created a clear opportunity to establish an API-first, modular backbone with orchestrated, auditable workflows and automated testing. By redesigning the service layer for performance and security, introducing stateful orchestration for regulated flows, and embedding CI-driven testing with environment parity, Fundment could unlock faster delivery, predictable scalability, and a compliance-ready operational posture.
Success meant a backend that was secure, scalable, testable, and easy to maintain for future updates.
The Solution
Aegasis Labs designed and built Fundment’s backend into a modular, cloud-ready platform. The new foundation focuses on secure APIs, orchestrated financial workflows, and automation across the delivery lifecycle—so the product team can scale confidently while meeting regulatory expectations.
We worked with Fundment to deliver a cloud-based backend that enabled:
- We created Secure and scalable API infrastructure, supporting core financial and compliance operations across the platform
- Automated testing and validation pipelines, using Pytest and Docker to ensure continuous code quality and faster iteration cycles.
- Seamless integration with AWS Step Functions, enabling orchestration of complex workflows related to financial transactions and regulatory processes.
- Technical mentoring for internal teams, providing best practices on clean code, version control, and modular system design to support long-term maintainability.
Technologies used:
- Python with Pytest for automated testing
- Docker for environment parity and reliable deployments
- AWS Step Functions for workflow orchestration
- Native AWS services (e.g., Lambda, API Gateway, CloudWatch, SQS) for secure, scalable execution
- CI/CD pipelines and infrastructure-as-code to optimize delivery and operations
The Results
Aegasis Labs designed, implemented, and embedded a modern backend foundation for Fundment that delivers measurable operational and engineering gains:
- Predictable performance at scale: The re-designed API layer sustains higher concurrency with stable latency and error tolerance, supporting growing adviser activity without service degradation.
- Compliance-ready workflows: Regulated, multi-step processes run on auditable state machines with retries, compensations, and immutable activity logs improving control and evidence for reviews and audits.
- Stronger security posture: Versioned endpoints, request/response validation, and role-based access standardize protections across services.
- Long-term maintainability: Modular service patterns, documentation, and mentoring uplift internal engineering capability unlocking faster feature delivery without compromising stability.
- Future-proof integration surface: A clear, versioned API contract enables partner and product expansion with minimal change management.
- Technical Team mentoring, providing best practices on clean code and version control, to build sustainable systems.
