Nexxen International
Nexxen International, the ad-tech firm run by founder Ofer Druker, unified demand and supply platforms under one Nasdaq-listed company.
Nexxen International
Nexxen International launched in 2007 as Tremor Video by Ofer Druker and Yaniv Carmi, focusing on video advertising technology. The firm spent over a decade building proprietary video demand-side capabilities before acquiring the supply-side platform Unruly in 2020 and RhythmOne in 2019, pulling together components that most ad-tech companies keep separate. The 2023 rebrand to Nexxen formally joined these previously distinct business lines and the firm delisted from the London Stock Exchange's AIM market to trade solely on Nasdaq. Nexxen operates a connected-TV and programmatic advertising stack that spans both a demand-side platform for media buyers and a supply-side platform for publishers. The integrated model gives the firm visibility into ad serving across streaming platforms, linear TV extensions, and digital video inventory. Confirmed integration partners include Roku and LG Ads, while data partnerships with firms like Comscore provide the measurement and audience verification layers that agency buyers require. Its geographic footprint covers North America, the UK, and Israel, with sales operations extending into Europe and Asia-Pacific. Following the Unruly and RhythmOne acquisitions, the combined group serves over 1,000 publisher partners and thousands of advertiser accounts. The firm maintains core engineering hubs in Tel Aviv alongside commercial offices in New York and London. In May 2023, the company completed its rebrand and consolidated its Nasdaq-traded identity under the ticker NEXN, signaling the formal end of its multi-year integration effort (per the firm's official communications, 2023). Nexxen's structural differentiator lies in the rare convergence of demand and supply technology in a single public company, a model that the Trade Desk and Magnite deliberately avoid cross-owning. The integration gives Nexxen access to supply-path optimization data that pure-play DSPs cannot replicate, though it means competing directly with the largest agency holding companies on one side and the largest publishers on the other. CEO Ofer Druker, an original founder, remains the operational anchor, maintaining founder-led continuity unusual for a company of its age and Nasdaq-listed scale.

Frequently asked questions
Who runs investment decisions at Nexxen International?
Nexxen is a publicly traded operating company, not an investment firm. Capital allocation decisions rest with the CEO and board. Ofer Druker has led the firm since founding it as Tremor Video in 2007. The company makes M&A decisions rather than portfolio allocations, with the 2019 RhythmOne and 2020 Unruly acquisitions forming the current platform.
How does Nexxen source its M&A and partnership targets?
Nexxen has historically pursued strategic acquisitions that fill technology gaps in its unified demand-and-supply platform. The firm targets companies with complementary data, measurement, or inventory relationships rather than financial roll-ups. The integration of Tremor Video, RhythmOne, and Unruly reflects a build-and-consolidate strategy common among founder-led ad-tech companies seeking scale against Alphabet and Amazon.
What differentiates Nexxen's platform structure from pure-play DSPs or SSPs?
Unlike standalone demand-side platforms such as The Trade Desk or dedicated supply-side platforms like Magnite, Nexxen owns both sides of the programmatic transaction. This gives the firm end-to-end visibility into bid-stream data, enabling supply-path optimization that independent DSPs must negotiate through external SSPs. The model mirrors parts of the Amazon Advertising and Google Ad Manager stack but without the walled-garden commerce or search data.
What is the relationship between Nexxen and the original Tremor Video?
Tremor Video was the founding entity, launched in 2007 by Ofer Druker and Yaniv Carmi. Through acquisitions of RhythmOne (2019) and Unruly (2020), the group expanded beyond demand-side video into supply-side ad serving. The parent holding company was renamed Tremor International before a full rebrand to Nexxen International in 2023, retiring the original Tremor name in favor of a new identity that reflected both DSP and SSP capabilities.
Where does Nexxen's underlying corporate wealth and shareholder base come from?
Nexxen is not a family office or founder-controlled private entity. It trades on Nasdaq under ticker NEXN. Significant institutional holders include public-market asset managers that invest in small- to mid-cap technology companies. Ofer Druker and the founding team retain meaningful but not controlling equity stakes, with governance subject to standard Nasdaq-listed company requirements.
