Overview
Nexxen is the trading brand of the publicly listed advertising technology company formerly known as Tremor International Ltd. The company operates a technology platform serving both advertisers and publishers, with capabilities spanning programmatic media buying, video advertising, mobile advertising, native and display formats, and connected television. Its business is intended to help advertisers reach audiences and measure campaign performance while helping publishers monetize digital inventory. The company began in 2007 under the name Marimedia, founded by Maia Shiran and Ariel Cababie with an initial focus on digital advertising monetization. Its early technology platform, Ad$Gadget, was introduced in 2011. The business subsequently expanded through investment, acquisitions, public-market activity, and successive changes in corporate identity. In 2010, Hagai Tal and Ehud Levy acquired a 50% stake, with Tal later becoming chief executive. Marimedia acquired mobile advertising company Taptica in 2014 and used an AIM listing in London to raise £17.9 million to help fund the transaction. In 2015, the company adopted the Taptica name. Under the Taptica identity, the company pursued a broader advertising-technology strategy. It acquired social-marketing technology company AreaOne in 2015, bought a majority stake in Japan-based Adinnovation in 2016, and acquired Tremor Video's demand-side platform in 2017. These transactions expanded its capabilities across mobile, social, video, and automated media buying. The company later merged with RhythmOne in 2019, appointed Ofer Druker as chief executive of the combined business, and changed its name to Tremor International. Tremor International continued to build its advertising technology portfolio through acquisitions. In 2020 it acquired Unruly, a video advertising platform previously owned by News Corp. In 2022 it completed the acquisition of Amobee for $239 million, adding a broader set of data-driven, cross-channel advertising capabilities. The company rebranded as Nexxen in 2023, presenting the business as an integrated advertising technology platform with particular emphasis on premium video, connected television, programmatic buying, and measurement. Nexxen is publicly traded in the United States and the United Kingdom under the ticker NEXN, with shares listed on Nasdaq and the London Stock Exchange according to the cited reference material. The company has reported a global workforce of more than 800 people across 19 offices. Its present market position is that of an independent advertising technology provider connecting media owners, agencies, advertisers, and audiences across digital channels. Specific current executive, ownership, website, and financial details are not supplied in the available reference material.
History
Nexxen traces its origins to Marimedia, a digital advertising monetization company founded in 2007 by Maia Shiran and Ariel Cababie. The early business concentrated on helping digital publishers and advertisers generate value from online traffic. Its principal technology platform, Ad$Gadget, was launched in 2011. A significant ownership change occurred in November 2010, when Hagai Tal and Ehud Levy acquired half of the company. Tal later became chief executive in December 2013. Levy was also associated with Taptica, a mobile advertising technology company that became important to the group's later identity and development. In 2014, Marimedia acquired Taptica. To support the transaction, the company listed on London's AIM market and raised £17.9 million. In 2015, it changed its name to Taptica, signaling a strategic shift toward mobile and performance-oriented advertising technology. The company then acquired AreaOne, a social marketing technology business, in September 2015. In 2016, Taptica acquired 57% of Japan-based Adinnovation for $5.7 million, extending its geographic and mobile advertising reach. Taptica broadened its programmatic and video capabilities in 2017 by acquiring Tremor Video's demand-side platform for $50 million. The transaction provided technology for automated media buying and later influenced the company's next corporate name. In December 2018, Hagai Tal stepped down as chief executive after a United States court ruling concerning the concealment of material facts during the 2011 sale of Plimus. The company merged with RhythmOne in February 2019. Because both businesses were publicly listed, Taptica retained its listing and RhythmOne shares were converted into Taptica shares. Ofer Druker was announced as chief executive of the combined company in April 2019. In June of the same year, Taptica adopted the name Tremor International. The enlarged business continued its acquisition-led expansion. In 2020, Tremor International acquired Unruly from News Corp. Unruly brought video advertising and publisher monetization capabilities. In September 2022, Tremor International completed the acquisition of Amobee for $239 million, adding broader cross-channel advertising technology and data capabilities. In 2023, Tremor International rebranded as Nexxen. The new identity positioned the company around the convergence of digital advertising, premium video, connected television, programmatic buying, and measurement. Nexxen is described as headquartered in New York and operating internationally, with more than 800 employees across 19 offices. Its shares trade under the symbol NEXN on Nasdaq and the London Stock Exchange according to the available reference material. The supplied sources do not establish the current chief executive, exact office locations, current ownership structure, or official website.
