About DOmedia

DOmedia is the leading software provider for the out-of-home (OOH) advertising industry, operating since 2007. Their platform connects media buyers at major advertising agencies with outdoor advertising inventory from over 1,200 media companies.

The company offers software solutions for both sides of the OOH marketplace: agency software for professional media buyers managing large campaigns, and sales software for media companies managing inventory, pricing, and transactions. DOmedia also operates BillboardsIn, a subsidiary platform that connects small businesses with local out-of-home advertising options.

The Challenge

Supporting a platform at the center of the OOH advertising industry requires handling complex data and diverse stakeholder needs.

The platform manages inventory data from 1,200+ media companies with millions of advertising locations, requiring robust data architecture and fast query performance.

Complex Integrations

Media buyers and sellers use diverse systems, requiring flexible API integrations and data synchronization across multiple platforms and formats.

Agencies need instant access to campaign performance, inventory availability, and market insights to make timely buying decisions.

Multi-Stakeholder Workflows

The platform serves agencies, media companies, and advertisers — each with distinct workflows, permissions, and reporting requirements.
