About Us

We don't chase tools. We build AI around the work, not the hype.

The Problem

Everyone is deploying AI. Few are asking why.

The pressure to adopt AI is everywhere right now. Teams are bolting it onto processes nobody redesigned, automating work that didn't need automating. The questions that matter go unasked: what is this actually for? Where does it genuinely help? And where should a person stay in the loop?

When the tool drives the decision, the decision suffers.

The result is predictable. Systems that collapse the moment they meet production. Teams pushed onto tools they never asked for. Budgets spent automating the wrong things.

The Founder's Journey

Luka Bojović

Cambridge · Microsoft AI

Luka Bojović

Co-Founder · Project Lead & AI Architecture

An IPhO and IOAA medalist and national champion in high school mathematics and physics, Luka read engineering at Cambridge and joined Microsoft, where he became the lead program manager on more than twenty AI features now used by millions — Paint Cocreator, Windows Recall, Live Captions, Studio Effects. That taught him what AI looks like when it has to survive review by a billion users: what breaks, what people actually trust. Aries's founding engagement was Sanbo — an AI-native platform for private capital markets — which the practice helped scale from zero to $1m ARR and over $1b in AUM. Aries AI exists because those two worlds rarely meet: the people who know how to build AI, and the firms that need it to hold up in production and under audit.

Stefan Badža

Co-Founder · AI Strategy, Public Sector & Enterprise Security

An IOAA medalist, Stefan saw the other side of the table first: in the Office of the Prime Minister of Serbia he worked on national AI strategy — the policies, procurement and governance that decide what AI is allowed to touch — and helped build Hub 201, one of the region's leading technology hubs. He knows why AI projects stall inside institutions, and how to keep them moving without cutting the controls that make them usable. He brings the security and governance lens that lets AI ship inside regulated environments — the architecture, identity and access, and the audit trail that a compliance team can actually sign off.
