We don't sell hours — we ship systems. Pick the entry point; the engine underneath is the same.

About the firm

A small firm with a long memory.

Ars Arcana LLC was incorporated in Wyoming on October 23, 2025 to consolidate the marketing, AI and consulting work we've been delivering to founders for years under different banners.

The firm is run by Silviu Laurentiu Rus — operator, marketer and engineer — and collaborates with a curated bench of specialists when a project calls for them.

Our work tends to be quiet. Our clients tend to compound.

Our approach

Three principles we don't compromise on

I.

Ship the system, not the slide deck

Strategy that doesn't end in something running in production is theatre. We build it, instrument it, and stay around long enough to see what it does.

II.

Own your stack, own your data

We default to architectures where the client owns the workflows, the models, the customer data and the infrastructure — not us, not a SaaS.

III.

Compounding over fireworks

We optimise for the curve, not the quarter. The smallest interesting clients compound into the only kind of moat that ages well.

We work with a small number of clients each year.
