QStart Labs has deployed a team of engineers embedded within DOmedia's technology organization, contributing to their industry-leading platform that connects advertising agencies with out-of-home media inventory across the United States and Canada. Our team works on platform development, API integrations, and new product initiatives including the BillboardsIn consumer marketplace.

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.
