Permutive is announcing that it has raised $18.5 million in Series B funding, as the London-based startup works to help online publishers make money in a changing privacy landscape. CEO Joe Root, who co-founded the company with CTO Tim Spratt, noted that publishers are facing increasing regulation while web browsers are phasing out support for third-party cookies — all good news for privacy advocates, but with a real downside for publisher ad revenue (blocking cookies causes an average 52% decline in ad revenue, according to a Google study last year). Permutive tries to address this issues by allowing publishers to utilize their own first-party data more effectively.
