Built by
Practitioners.
A Lithuanian IT consultancy that ships its own products. We bring 20+ years of fintech, AI, and blockchain experience — from leading Paysera to building open-source banking — directly to your project.
Our Name, Our Principles
Our company name reflects how we work. Each word maps to a principle we follow in every project.
Aegis
The Shield
We design with threat models upfront and write tests before production code. Our FinAegis platform uses event sourcing to enable full replay and debugging of every state change.
Brightsmark
The Beacon
We adopt event sourcing, domain-driven design, and privacy-preserving protocols — patterns widely used in fintech — and apply them to new domains like sustainability and digital commerce.
Capital
The 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.
