Swiftmile has expanded their programmatic digital out of home (DOOH) advertising capabilities by partnering with Lemma, a supply side platform (SSP). This will allow Swiftmile's US inventory to be purchased programmatically by global advertisers through Lemma's platform. The partnership will provide media buyers in the US, Asia-Pacific, and Europe with seamless access to Swiftmile's DOOH screens. It is anticipated to boost fill rates and yields by sourcing demand programmatically. Swiftmile and Lemma see the collaboration as an opportunity to deliver more brand messaging to relevant audiences through outdoor media.
