Does HIRO provide its own demand?

Unlike other solutions, HIRO does not provide its own demand. Instead, we boost bid density by connecting your inventory to an ecosystem seeking addressable audiences. This drives DSP competition, increasing your revenue by leveraging the demand from your opted-in audiences and CRM data.

Can I still benefit from HIRO if I’m already utilizing stable IDs across my domains?

Absolutely! HIRO complements other stable IDs like UID 2.0 by enhancing scale and enabling additional identifiers across multiple supply platforms. In fact, many partners have seen a 30% increase in incremental revenue when combining HIRO with existing stable IDs.

What if I require assistance during setup?

Our streamlined onboarding process ensures a quick and efficient path to revenue. Our solutions engineering team will guide you through best practices and assist with any technical questions during setup.

Does HIRO take our data?

No. Unlike other identifiers, HIRO does not take any data from your site to create lift.

HIRO isn’t just another product — it’s an essential tool that helps us drive real revenue for our publishers. We independently validated the performance through our own framework, and the results speak for themselves: increased monetization, better CPMs, and more money in our publishers’ pockets. That’s value we can prove.

The ad-tech space is full of overhyped solutions that don’t deliver, but HIRO is the real deal. It seamlessly bridges the gap between our publishers and the demand side, turning non-addressable audiences into real revenue. It’s refreshing to work with a partner that actually delivers on its promises—HIRO has driven measurable CPM lifts and proven itself as a critical piece in our ability to drive monetization for our creators and publishers.
