Suno, the Cambridge-based AI music generation platform, has closed a $400 million Series D round led by Bond Capital, alongside IVP, Forerunner, Union Square Ventures, Alkeon, and Quiet, more than doubling its valuation from $2.45 billion just seven months ago.
Co-founder and CEO Mikey Shulman said the capital will fund new product launches, expanded offerings, and workforce growth of up to 70 percent before year-end, scaling from a current headcount of around 200. As of February, Suno had surpassed two million subscribers and was projecting $300 million in annual revenue.
A jointly developed music model with Warner Music Group — which resolved its copyright claims against Suno last November via a licensing deal — is expected to reach users within months. However, Universal Music Group and Sony Music continue to pursue copyright litigation, with labels alleging more than 61,000 songs were used in training data without authorisation. Class-action suits backed by over 1,800 independent artists are also proceeding against Suno and rival Udio.
Despite the legal backdrop, Suno’s platform — which generates finished songs from text descriptions of mood, style, or instrumentation — has reached the top of App Store music charts in dozens of countries.
