About
Mirelo is solving the "silent problem" in AI video generation: AI-generated videos have no synchronized, contextually appropriate sound. The company raised $41 million in seed financing led by Andreessen Horowitz and Index Ventures in December 2025, and launched SFX v1.5 and Mirelo Studio in early 2026. The platform generates synchronized sound effects, ambient audio, and music that matches the visual content of AI-generated or edited video.
NYSE: U real-time 3D engine used by 20M+ developers for mobile and cross-platform games at $1.81B FY2024 revenue; Unity 6 and Matt Bromberg leadership rebuilding after 2023 Runtime Fee controversy competing with Unreal Engine.
About
Unity Technologies is a San Francisco-based real-time 3D development platform — listed on NYSE (NYSE: U) — providing game developers, film studios, automotive engineers, and enterprise architects with the Unity Engine (one of the world's two dominant game engines alongside Unreal Engine), Unity Gaming Services, and the Unity Ads monetization network, used by 20+ million registered developers to create mobile games, PC and console titles, VR/AR experiences, architectural visualizations, and interactive automotive configurators. Founded in 2004 by David Helgason, Joachim Ante, and Nicholas Francis in Copenhagen and headquartered in San Francisco, Unity generated $1.81 billion in revenue in fiscal year 2024 as the company navigated one of the most turbulent periods in its corporate history — a controversial Runtime Fee pricing change announced in September 2023 that triggered massive developer backlash and was ultimately reversed, followed by the resignation of CEO John Riccitiello and appointment of Matt Bromberg as new CEO in 2024.
