DOmedia is a B2B marketplace and workflow platform for planning, buying, and selling out-of-home (OOH) advertising inventory. It centralizes and standardizes key OOH steps—inventory discovery/search, RFPs, proposals, contracting, and measurement/verification integrations—across multiple media owners and suppliers, and is intended to reduce reliance on spreadsheets and email for transaction workflows. DOmedia also operates a self-serve, local-advertiser-oriented offering presented as an online buying and planning platform for local advertisers.
