Sundar Arvind has taken investment raised by his second startup past £5 million – and he is only 23.
Yet that is only half of the story.
Arvind was a precocious tennis player who turned professional aged 12 and was ranked third in India and the top 1,000 in the world. He faced the likes of Jack Draper and Carlos Alcaraz across the net.
However repeated injuries led to enforced rest periods and so he turned his attention to music.
“One day I just decided to become a music producer, so I swapped out my racquet for decks and became the first Indian to sign with Warner Bros Music,” he wrote on Instagram.
He was aged just 14 when he won that recording contract with Spinnin’ Records and has since amassed millions of streams on Spotify.
After achieving four A* grades in his A-Levels, he took the advice of his father and studied computer science (artificial intelligence) with management at King’s College London, which included a year in industry.
He graduated with first class honours in 2024. That same year he began building his first startup Blitzo – an AI-powered delivery platform which quickly reached £1.8m in annual recurring revenue – with Arjun Khanna, who has represented India in global maths competitions and Harvard debates.
“I’ve always been the type of person to trust my gut. I found my place at King’s and London felt right,” Arvind said.
“The only thing which didn’t click into place was the lack of convenience with UK delivery services… my gut told me to create the convenience myself. So I did, and Blitzo was born.”
Now the CEO is returning to music with Mozart AI, a startup founded with COO Khanna (pictured below, right) and CTO Pascual Merita Torres (below, left), a producer and DJ, classically trained pianist and AI researcher.
Described as a generative audio workstation, it aims to enhance workflows that lead to faster track completion times. Launched late last year, it already boasts 100,000+ users within two months and a million songs created.
Artists using the platform include Frans Mernick (ASAP Rocky’s producer), Ash Pournori (Avicci’s songwriter) and Kodak Black’s producer.
‘Audoo is a mission-led business – we’re not focused on exit’
Following a pre-seed round last year, Arvind has now raised £4.4m in an oversubscribed seed round led by Balderton Capital while it has also launched a mobile app. It takes total funding past £5m.
Mercuri (early stage MediaTech VC), EWOR, Kevin Hartz (Eventbrite founder), Charles Ferguson (Oscar-winning director of the Inside Job documentary) and Emery Wells (Frame.io founder) participated in the round, alongside existing investors and strategic angels from music, AI and creator technology.
The funding will be used to grow the team, expand Mozart AI’s core tech, and build on the viral success of its beta launch ahead of a full public release.
Mozart AI is built on top of commercially cleared third party generative models. ElevenLabs, one of the company’s primary model providers, is only trained on licensed materials, which allows the users of Mozart AI to freely use their music in commercial areas.
“The creative process has always been integral to music-making and to music’s role in shaping global culture,” said Arvind. “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.”
Umair Ali, Kodak Black and Lil Baby’s producer, said: “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.”
