MarqVision reports 47x growth in fake website detections and 3x growth in paid ad abuse as it expands leadership with former Amazon, TikTok Shop, and People.ai executives
SAN FRANCISCO, May 13, 2026 /PRNewswire-PRWeb/ -- MarqVision, the AI-powered managed service platform for brand control, today announced strategic leadership appointments as the company expands its response to the rapid rise of AI-driven online brand abuse across ecommerce, social platforms, paid advertising channels, domains, and the open web.
New company data shows the scale and sophistication of these threats accelerating rapidly. In Q1 2026, overall AI-driven brand-threat detections on MarqVision's platform grew more than 16x year over year, while fake website detections grew 47x and paid ad abuse tripled. Counterfeiters, impersonators, scam networks, and unauthorized sellers are increasingly using AI to create fraudulent storefronts, fake websites, scam advertisements, and counterfeit listings at a scale traditional enforcement systems were never designed to handle.
What was once primarily a legal or compliance issue has increasingly become a customer trust, revenue, and business continuity problem that moves at AI speed. According to MarqVision's 2026 State of Brand Integrity Report, 57% of brands reported seeing fake content appear within one week of a brand going viral, while nearly one quarter reported seeing it appear within 48 hours.
MarqVision says brands increasingly experience these attacks not as isolated categories, such as counterfeit versus impersonation versus fake domains, but as interconnected "fake-channel" ecosystems spanning multiple digital surfaces simultaneously. The company's internal analysis found that 87% of anti-counterfeit customers also experienced brand impersonation incidents.
"Generative AI has dramatically lowered the barrier to creating convincing counterfeit storefronts, impersonation campaigns, fake domains, and scam ads at scale," said Mark Lee, Founder and CEO of MarqVision. "Counterfeits, impersonation, fraudulent websites, and scam networks are no longer isolated problems. They're interconnected business threats that can impact customer trust and revenue almost overnight. Brands need systems built to operate at the speed and scale these threats now move."
Building the Infrastructure Behind Modern Brand Protection
As brands face growing pressure to respond faster across increasingly fragmented digital channels, MarqVision also announced two strategic executive appointments aimed at accelerating the company's next phase of growth across platform partnerships, enterprise operations, and legal enforcement. Kaleigh Miller joins as Global Head of Ecosystem & Platform, while Dana Herstein joins as Global Head of Sales.
The hires bring together experience across marketplace governance, ecommerce operations, enterprise growth, and intellectual property enforcement at a time when brands are struggling to keep pace with how quickly AI-driven threats now spread online.
With the appointments, MarqVision is expanding beyond traditional takedown-based enforcement toward a more connected model of brand protection, combining AI-driven detection, deeper partnerships across platforms and marketplaces, business-impact intelligence that helps brands quantify revenue exposure, and MarqLaw's online-to-offline capabilities spanning investigations, customs coordination, litigation support, and complex disputes.
Miller spent more than six years at Amazon leading global brand protection engagement and later overseeing seller experience for product safety and compliance initiatives. She later joined TikTok to lead Seller and Listing Governance during the U.S. launch of TikTok Shop and most recently served as Chief of Staff to the Group CEO at Articore Group, parent company of Redbubble.
At MarqVision, she will lead the company's global platform and ecosystem strategy across marketplaces, social commerce platforms, ad channels, domain providers, and emerging AI-commerce environments, while also helping expand MarqLaw's global legal enforcement capabilities — the company's in-house legal services practice that connects online detection with offline investigations, litigation support, customs coordination, and complex disputes when online action is not enough.
"The volume and coordination of these threats is changing how platforms, marketplaces, and brands have to work together," said Miller. "The future of brand protection has to be much more embedded in the ecosystems where abuse originates."
Herstein joins MarqVision to lead the company's global sales organization and enterprise growth efforts across North America, Europe, and Asia. He brings more than two decades of revenue leadership experience at high-growth technology and data businesses, including Extend, People.ai, Kantar, SurveyMonkey, and Business Insider. He also holds a J.D. in Intellectual Property from Fordham University School of Law, bringing experience from both sides of the problem, spanning IP law and enterprise revenue.
"Online abuse is no longer just a legal or compliance issue," said Herstein. "What's changed is that the attack surface has moved from purely legal to commercial. Counterfeits and impersonation campaigns are now directly suppressing customer acquisition and ecommerce performance, which makes this a revenue conversation, not just an enforcement one. And this is changing how companies think about brand protection."
