The breakup of ironSource continues with Supersonic's $40 million sale to Tripledot. Unity has completed the sale of the Israeli mobile game publisher, further unwinding the businesses it acquired in the landmark 2022 merger. 21:48, 06.08.26 The dismantling of ironSource inside Unity is nearly complete. More than four years after Unity acquired the Israeli technology company in a $4.4 billion merger that was billed as a transformational deal for the mobile gaming industry, one of ironSource's last remaining businesses has changed hands once again. On Thursday, Tripledot Studios, a London-based mobile game developer co-founded by Israeli entrepreneurs Lior Shiff and Eyal Chameides, announced that it has completed the acquisition of Supersonic, the Tel Aviv game publishing business created by ironSource, for $40 million in cash. The deal, which officially closed earlier this week, gives Tripledot its first presence in Israel while marking the third ownership change for Supersonic in just six years. Originally established inside ironSource, the publisher became part of Unity through the companies' 2022 merger and is now joining one of the world's largest private mobile gaming companies. Unity had disclosed in March that it planned to sell Supersonic as part of a broader effort to simplify its business, alongside the shutdown of the former ironSource advertising network. At the time, neither the buyer nor the purchase price was revealed. According to Unity's latest quarterly report, Tripledot agreed to pay $40 million in cash, subject to customary post-closing adjustments. Unity valued Supersonic's assets at approximately $56 million and its liabilities at nearly $20 million. For Israel's gaming industry, the transaction closes another chapter in the gradual disappearance of ironSource as an independent force. When Unity acquired ironSource in 2022, the Israeli company contributed three core businesses: its advertising platform, Aura, and Supersonic. The advertising business, once expected to become a cornerstone of Unity's strategy, was instead phased out as the company invested in its own advertising infrastructure. Earlier this year, Unity announced the closure of the ironSource Ad Network, while several of ironSource's founders and senior executives had already departed the company. Supersonic had remained one of the few prominent Israeli businesses still operating inside Unity. Founded six years ago, the Tel Aviv-based publisher built its business around helping independent studios launch and scale casual and hybrid-casual mobile games. Since its creation, it has published more than 150 titles, including hits such as Going Balls, Bridge Race, Build A Queen, Hole It and Unravel Master. Collectively, its games have been downloaded more than 6 billion times. Tripledot said the acquisition significantly expands its publishing business at a time when artificial intelligence is lowering the cost of game development while making distribution increasingly valuable. "The best games do not always come from the biggest companies," said Tripledot co-founder and CEO Lior Shiff. "As AI lowers the barriers to developing a high-quality game, the constraint for a small studio is no longer building a game, but bringing it to market and scaling it to millions of players." The company said operating Supersonic alongside Lion Studios, the publishing platform it acquired last year, will allow it to work with more independent developers while strengthening its publishing capabilities through user acquisition technology, data science and engineering resources. The acquisition also represents Tripledot's first expansion into Israel. The company said Supersonic will serve as its local hub, giving it access to the country's mobile gaming talent while continuing to operate independently under its existing management team from Tel Aviv. Supersonic General Manager Igor Bereslavski said the company's mission would remain unchanged. "Everything Supersonic has built rests on a simple idea: a small team with a great game should be able to reach the whole world," he said. "Tripledot believes the same thing and brings the scale to do it properly."

Tripledot Studios has acquired Supersonic from Unity for approximately $40 million, GamesBeat has learned exclusively. The deal has closed, with Unity supporting a three-month transition period. London-based Tripledot makes casual puzzle and mobile games including Woodoku, Triple Tile and Nut Short. Supersonic came to Unity through its 2022 merger with ironSource, valued at $4.4 billion. The acquisition allows Tripledot to expand its publishing capabilities whilst Unity refocuses on its core game engine and Vector AI advertising platform. Supersonic's developer partners will retain the same team and tools, now backed by Tripledot's resources. Tripledot has raised $202 million across three funding rounds, with its Series B in 2022 valuing the company at $1.4 billion. In May 2025, it acquired 10 studios from AppLovin for $800 million.
