Virtual Arc AI Systems — Belgrade, Serbia

Ambitious ideas. Engineered to work.

AI systems, business software and websites. Built around your business. Designed, engineered and supported by one team.

Kingpin, a sales-intelligence platform in Dubai, runs on an AI system we engineer. We delivered Content Studio for DesignRush in the US in 2025, wrote Java Spring backends for Swiss intralogistics for around five years, and three Serbian companies run their daily operations on systems we built — one of them since 2018.

What we do

AI engineering

Agentic and retrieval systems, multi-provider orchestration, and the billing, permissions and audit around them.

Business systems

ERP, B2B portals and internal platforms.

Websites

Company websites, including KORALI's official site.

What we engineer

Two of our own systems run this site: the assistant on this page, grounded in our own material, and the research pipeline that writes the Journal every morning.

Multi-provider data orchestration across Ocean.io, Apollo, Hunter and FullEnrich behind one interface, with validation LLM agents, a credits system and Stripe billing in the same platform. Kingpin, Dubai.

Agency descriptions generated inside the product, with RBAC over teams, roles and permissions. Content Studio, DesignRush.

Asynchronous generation of 7-to-180-day plans: one failed batch fails the whole job, so a half-finished plan is never handed over. ArcFit.

Authorization by capability and by organizational scope, checked server-side on every call. ArcClock.

Our platforms

ArcFin — ERP · statutory layer

An ERP for Serbian manufacturers built around statute: e-invoices filed to Serbia's SEF as UBL 2.1, POPDV and PP-PDV returns, an append-only ledger where corrections are reversing entries, and statutory values versioned by effective date. Tenant separation is enforced by the database.

ArcFit — Gyms · AI plans

Gym operations, plus 7-to-180-day nutrition and training plans generated asynchronously. Access is invitation-only.

ArcClock — Organization · workforce time

Legal entities, workplaces, departments, teams, positions and calendars. MFA with recovery codes, revocable sessions, and an audit trail the running system cannot alter. Serbian Latin, Serbian Cyrillic and English.
