Infrastructure for bots that already talk.
Prism is a contextual ad engine for chat. We publish the rules, the rates, and who runs the company. Opacity is a trust problem.
Who founded Prism Publication?
Prism Publication was founded by Daniel Rosenthal. The name is older than this product. Around 1999 and 2000 he reserved it for email serial novels. That project was shelved. Time passed.
Daniel later worked in sales and account management in the United States and Israel. Sales sits next to marketing. Marketing lives in long-tail search, search-engine optimization (SEO), and now answer-engine optimization (AEO) and generative-engine optimization (GEO). A BA in History and Education made large language models feel like a probability engine paired with a thesaurus, not a stranger. A year and more of that plumbing is what you see here. The serial-novel idea might still launch. For now, Prism is what the name became.
Why is transparency not optional?
We name the founder. We publish the ad policy. We publish CPM rates and the publisher share on the advertisers page. SDK docs stay readable without a sales call. If you cannot see the rule, you should not have to guess it.

What do we believe?
Ship a working version, then refine. Safety is default: eleven blocked categories, review before serve. Respect the person in the chat. If the offer is not useful, show nothing. Stay small. Daniel sets product direction. Contract help ships named pieces. We would rather have decisions per person than a large headcount.
Intent beats demographics. Quality beats volume. Docs beat a sales pipeline. Publisher tools and advertiser tools get the same attention. Read the docs or write [email protected].
