We name mechanics, not magic.
We will explain what bidding strategy we are choosing and why. If we cannot explain it in plain English, we will not run it.
A specialist agency for a new surface.
Cillex AI was founded as OpenAI's self-serve ad platform went GA in May 2026 — a moment we believe will reshape how brands acquire customers for the next decade. We do one thing, well, on purpose.

Three years from now, every brand will need an answer for this.
The numbers tell the story. OpenAI's self-serve Ads Manager went open in May 2026. Within six weeks it crossed roughly $100 million in annualized revenue with 600+ brands testing. The $50,000 minimum spend that gated the pilot was removed. Ads now appear inline beneath ChatGPT's answers — a new surface, with new mechanics, and almost no specialist agencies operating on it.
That is exactly the moment the social-ads agencies were born into in 2009, the moment the SEO agencies were born into in 2003. The first specialist firms define the playbook, and the playbook compounds. We exist to be one of those firms.
Four things we will and will not do.
We say no.
About one in four prospective clients leaves the first call with our advice to not work with us — yet. AI ads are not the answer to every demand-gen problem.
We work in plain documents.
No proprietary dashboards you have to log in to. The week ends with a single readable document; the month ends with a working session to interrogate it.
We measure what compounds.
CPA, ROAS, frequency, intent quality. The numbers that move the business, not the numbers that flatter the agency.
