Peer39

Peer39 operates as a data company providing contextual intelligence for the digital advertising sector. The firm was established in 2006. One of its co-founders is Amiad Solomon, a serial entrepreneur and investor with a background in adtech and AI. Solomon's experience is rooted in developing technologies that understand content semantics, a principle that has been central to Peer39 since its early days.

The company's history includes several ownership changes. In 2012, it was acquired by DG for $15.5 million, and two years later, it was spun off as part of a new entity called Sizmek. Following Sizmek's bankruptcy in 2019, Peer39 was sold to O3 Industries, a private equity firm, and a group of advertising industry veterans, re-establishing it as an independent company. This transition was led by Mario Diez as CEO and Alex White as COO, who aimed to capitalize on the growing importance of contextual data in a privacy-focused advertising landscape.

Peer39's business model centers on providing pre-bid data solutions that function without the use of cookies. It serves programmatic buyers, publishers, and brands by analyzing digital content environments—including web, mobile apps, online video, and Connected TV (CTV)—to ensure ad placements are relevant and brand-safe. Revenue is generated by offering access to its extensive library of data categories through major Demand-Side Platforms (DSPs). The core technology employs AI-powered semantic analysis and natural language processing to understand the meaning, sentiment, and quality of page content, going beyond simple keyword matching. This allows advertisers to target audiences based on the context of the content they are consuming in real-time.

The company's product suite includes a large library of over 300 contextual categories, brand suitability and safety controls, and page quality signals. A key offering is its platform that allows clients to build and manage custom contextual categories using keywords and Boolean logic. In 2021, Peer39 launched the Contextual Data Marketplace, a platform that gives advertisers access to cookie-free data sets from various providers, such as Newsguard and Planalytics, thereby expanding the range of available targeting signals. This marketplace enables partners to develop and distribute new data products through Peer39's infrastructure.
