About Us
Aegis Brightsmark Capital MB is a Lithuanian IT consultancy. We build software products at the intersection of fintech, sustainability, and blockchain technology.
What Our Name Means
Each part of our name reflects a core principle in how we work.
Aegis (Protection)
We design with threat models, maintain automated test coverage, and use event sourcing for full audit trails. Our FinAegis platform captures every state change as an event, enabling reliable replays and debugging.
Brightsmark (Innovation)
We adopt proven modern technologies — event sourcing, domain-driven design, embedded wallets — and apply them to solve practical business problems.
Capital (Expertise)
Our real capital is the products we build and maintain within the FinAegis ecosystem. What we learn from shipping our own code, we apply directly to client work.
“We build software products that matter to us — and we take full ownership of the code we write.”
Our Approach
The engineering practices we follow across all our projects.
Domain-Driven Design
We model complex business domains with bounded contexts and aggregates, keeping the software aligned with the business it serves.
Event Sourcing & CQRS
Full audit trails and temporal queries. Every state change is captured as an immutable event, enabling reliable replays and debugging.
Test-Driven Development
We write tests before production code. Our FinAegis platform uses Pest PHP with tests covering domain logic, projections, and API endpoints.
Open Source First
We believe in transparency. Our FinAegis banking domain model is Apache 2.0 licensed and publicly available on GitHub for anyone to audit.
Security by Design
Security is built into the architecture from day one, not bolted on afterwards. From key management to access controls, we think about threats early.
Ship & Iterate
We deliver working software early and improve it continuously based on real usage and feedback.
