Tunnl

Tunnl BV is a private Dutch AdTech company that operates a programmatic advertising stack and a managed media buying service. Its core commercial offering is a proprietary ad system connected to multiple SSP and DSP environments, used to run targeted campaigns, optimise bidding and delivery with machine learning, and report performance to advertisers, media buyers, and publishers. The company also sells managed programmatic execution for brands, agencies, and publishing partners. Alongside its AdTech activity, Tunnl states that it distributes a large portfolio of games and video content that can be monetised through advertising. This gives it both technology and inventory exposure: it can earn software and service revenue from campaign execution, while also generating advertising income from owned or controlled media supply. Some supplied product data also references audience intelligence and campaign measurement products on tunnldata.com, which creates a naming overlap that requires caution when attributing those assets directly to Tunnl BV.
