Mozart AI, a generative music creation startup, has raised £4.5 million in a seed round led by Balderton Capital, with participation from Mercuri, EWOR, Kevin Hartz, Charles Ferguson and Emery Wells. It brings music software into the AI age through its Generative Audio Workstation and has launched its mobile app. The funding will be used to grow the team, expand its core technology, and build on the viral success of its beta launch ahead of a full public release.
Mozart AI updates the Digital Audio Workstation for a new generation committed to creating and sharing music online. Its Generative Audio Workstation supports both ground-up music creation with AI assistance and prompt-driven agentic music creation. The software offers context-aware stem generation, real time suggestions for MIDI progressions and drums, synth and effect generation, and the ability to remix sounds into new styles, while automatically managing tasks such as quantisation and time stretching. Users retain copyright ownership and can create music videos for upload to social media platforms.
Since its September beta launch, it has seen more than 100,000 artists sign up in the first two months, with 1,000,000 songs created on the platform. Artists using it include producers for A$AP Rocky, Avicii and Kodak Black. Some artists have released music on Spotify achieving over 10m streams.
Founded in 2025 and based in London, Mozart AI is part of Arthos. CEO and co-founder Sundar Arvind previously signed to Spinnin’ Records at 14 and founded AI delivery startup Blitzo with Arjun Khanna. Pascual Merita Torres is a producer, DJ, classically trained pianist and AI researcher.
The creative process has always been integral to music-making and to music’s role in shaping global culture. Far from replacing creativity, AI is levelling up that adrenaline-filled process through which musicians compose and discover the right sounds. Mozart AI is building powerful generative tools for the next era of collaborative music creation that will enable every artist – from casual creators to professional producers – to turn any idea into a release-ready song in minutes, with commercial rights. We’re building toward a world where a spark of creativity – a guitar riff, a melody, an idea – can be transformed into a fully produced, monetisable song with a professional music video, without requiring technical knowledge or fragmented tools.
Sundar Arvind, Co-founder & CEO
AI is impacting every industry, and music is no different. The companies that win will be those that work with and for musicians, not against them. That’s why we’re so excited about Mozart AI, whose exceptional founding team includes musicians, technologists, and serial entrepreneurs, with deep roots in the industry. Instead of being stunted by clunky and inaccessible legacy software, Mozart AI enables musicians and music enthusiasts to spend more time on the actual creative process, experimenting and iterating on their ideas with ease and speed. This team is building with exceptional focus and we’re excited to invest in the next generation of music technology.

The big winners in the music AI race will be the platforms that present themselves as tools rather than threats to creatives. There’s an opportunity for technology to amplify and enhance talent, allowing more people to make and publish meaningful music without detracting from an artist’s skill or originality.
Ash Pournori, Producer
As a creative technologist and producer, Mozart Studio is one of the first AI music tools I’ve tried that actually accelerates ideation without flattening the creative process. It feels like an always-on sketchpad for hooks, melodies, and arrangement. It helps you get from a rough concept to something session-ready fast, then refine it like a real record.
