Company
We ran the sell side.Now we fight for the buy side.
RresponsIQ is built by Xyle, the company behind MonetiseUP. Running publisher-side auction infrastructure showed us exactly where advertisers lose money to opacity — so we built the DSP that gives it back.
The both-sides story
We've seen the auction from every seat.
MonetiseUP's sell-side stack processes billions of auction requests. From that vantage point, one pattern was impossible to ignore: advertisers paying bundled CPMs with no idea what the media actually cost, while layers of intermediaries took undisclosed cuts.
RresponsIQ is the answer we wished existed: a buy-side platform engineered on exchange-grade infrastructure, priced with radical simplicity, and accountable to the people signing the checks.

What we optimize for.
Absolute Transparency
If we can't show you the math, we don't ship the feature. Every fee, every hop, every decision is inspectable.
Speed-First Engineering
Auctions are won in milliseconds. We engineer for the 12ms decision, not the slide deck.
Customer Sovereignty
Your data, your audiences, your models. Portability is a feature we maintain, not a threat we manage.
