Clean.io raises $2.5M to fight malicious advertising

Existing approaches to blocking malicious advertising aren’t working — at least according to digital ad veteran Seth Demsey. That should resonate with anyone who’s ever encountered an ad that immediately redirected them to a website filled with annoying gift card offers. And it’s the issue that the startup Demsey co-founded, clean.io, is working to address. Today, the company is unveiling the new clean.io name (a rebrand from its old moniker of Clean Creative),  and also announcing that it has raised $2.5 million in seed funding from Real Ventures. “When you think about what we’re really dealing with, forget media, forget ads — we’re dealing with the beautiful openness of the web,” Demsey said. “That allows you to compose different elements from different people on the page, but that power of composition also opens the door to abuse.”
