Undertone

Premium high-impact ad format specialist operating as a subsidiary of Perion Network, serving Fortune 500 brands and major agencies

Undertone is a digital advertising company specializing in high-impact ad formats and cross-screen advertising solutions. Founded in 2001, the company built its reputation on delivering visually immersive, premium ad experiences that go beyond standard display advertising — including formats like interstitials, pushdowns, and rich media units designed to capture consumer attention without being intrusive. Undertone serves as a bridge between brand advertisers seeking premium placements and publishers looking to monetize their inventory with high-CPM, engaging formats. In 2015, Undertone was acquired by Perion Network, a Nasdaq-listed digital advertising technology company, for approximately $180 million. Under Perion's ownership, Undertone has continued to operate as a distinct brand and business unit, expanding its capabilities to include data-driven audience targeting, programmatic buying, and advanced analytics. The platform integrates creative, data, and distribution to help brands execute campaigns that resonate across desktop, mobile, and connected TV environments. Undertone occupies a notable position in the AdTech ecosystem as a specialist in high-impact creative advertising, differentiating itself from commodity display and programmatic players by emphasizing brand-safe, premium publisher relationships and proprietary ad formats. Its client base includes major brand advertisers and agencies seeking measurable brand lift and engagement, making it a key player in the upper-funnel advertising space.
