Suno, the AI music generation platform that lets anyone create songs from text prompts, just closed a funding round north of $400 million at a $5.4 billion valuation. That’s more than double the $2.45 billion price tag it carried just seven months ago after its $250 million Series C in November 2025.
The round was led by Menlo Ventures, where partner Amy Wu Martin apparently got hooked on the product by making AI-generated songs for her son. She led the firm into the Series C last fall and then came back for seconds. Bond Capital, IVP, Forerunner, Lightspeed, and Matrix also participated.
A growth story with a legal asterisk
The numbers backing up this valuation are genuinely impressive. Suno has roughly 2 million paying subscribers and is pulling in approximately $300 million in annual recurring revenue. Users are spending an average of 55 minutes per session on the platform.
For context, Suno raised $125 million in May 2024 at a valuation of around $500 million. So in roughly two years, the Cambridge, Massachusetts-based company went from $500 million to $5.4 billion.
