Montreal’s Hivestack is continuing to extend its reach, partnering with The Trade Desk to make its programmatic OOH campaigns available on a global scale.

The partnership will enable The Trade Desk advertisers to programmatically purchase DOOH inventory from the Hivestack SSP using the new Solimar DSP.

One of the biggest independent DSPs in the world, The Trade Desk launched Solimar earlier this month. Touted by The Trade Desk as “a DSP for the open internet,” Solimar is built on first-party data and its Unified ID 2.0 for a post-cookie, privacy-focused advertising landscape. It is also meant to take advantage of opportunities in new realms for programmatic advertising, such as DOOH and connected TV.

Hivestack currently claims to deliver 183 billion monthly impressions across North America, 63 billion in EMEA and 20 billion in APAC. The partnership with The Trade Desk adds to other efforts in a recent growth trajectory, including expanding access to advertisers in other markets, growing the inventory available on its platform and adding to its data capabilities.

Though Hivestack did not provide specific details, the first campaign in the partnership has now launched within Canada, and further rollout will focus on markets that have both strong digital inventory and active demand from clients.

To that end, the companies have pegged Singapore and Hong Kong for the next step of the rollout, before going to the U.S., Japan, U.K., Germany, France, Netherlands, Belgium, Spain, Italy, Mexico, Korea, Malaysia, Thailand, New Zealand and China.
