Willard Ahdritz left Kobalt Music Group on July 7, the day Primary Wave Music‘s acquisition of the company closed.
Twelve weeks later, he has a new firm.
Ahdritz Capital Partners (ACP), a music and media technology investment firm, launched on Thursday (October 1).
Isabel Keulen joins as an Investment Partner, based in Stockholm, alongside Founder & Managing Partner Ahdritz and Investment Partner Stephen Langer, a former Lazard banker who started at the firm in May – two months before the Kobalt sale completed.
ACP says it operates as one global team across New York and Stockholm, and will target technology investments in media infrastructure and systems, as well as fandom and audience platforms.
The firm has not disclosed a fund size, a target raise, or any outside limited partners.
“Music is global, yet the capital and networks founders need have been concentrated in a few cities,” said Ahdritz. “We want to support founders and innovation not only in those markets, but also in other parts of the world too.
“After investing on my own for the last few years, the moment felt right to put together a great team to invest in and advise promising entrepreneurs.”

That last line matters for reading the timing. ACP is less a standing start than a formalization of activity Ahdritz has been running in parallel with Kobalt for years.
In 2023, while still Kobalt’s Chairman, he led a seven-figure funding round in UK-born artist marketing platform un:hurd.
At that point, MBW reported that Ahdritz had set up two entities of his own: an investment advisory firm, Ahdritz & Co, and an investment vehicle, Ahdritz Holding LLC.
The year before that, he was named as an investor in a USD $200 million fund established to back tech startups in Africa.
Ahdritz founded Kobalt in 2000 and led it for more than two decades as CEO and then Chairman.
In its launch announcement, ACP describes the company he built as “one of the largest independent music companies in the world.”
ACP also credits Ahdritz with co-founding AMRA, which it calls “the global digital collection society.”
MBW‘s own record is that Kobalt acquired the American Mechanical Rights Agency in 2014, relaunching it the following year as the American Music Rights Association.
He stepped down as Chairman of Kobalt’s board when the Primary Wave transaction closed. MBW understands that deal was worth around USD $1.5 billion.
It covered Kobalt‘s worldwide operations, its catalog of owned copyrights, and its digital collection society, amra.
The AI thread runs through ACP‘s framing of its own hires.
Commenting on the latest appointment, Ahdritz said: “In Isabel, we have the best of the new AI investor generation. What has impressed me is her insight and her judgement. She sees things early and she sees them correctly.
“Entrepreneurs greatly value her ongoing collaboration and wisdom. I am excited to have her join me and Stephen at ACP as a Partner.”
Keulen was CEO of SSE Business Lab, which the Financial Times has ranked among Europe’s top ten startup hubs, and of SSE Ventures, the venture fund attached to it at the Stockholm School of Economics.
She continues as Senior Advisor to both organizations. Before SSE, she was a Principal at Spintop Ventures, backing early-stage technology companies.
“Today, Stockholm produces more unicorns per capita than any city outside of Silicon Valley, with several of the biggest tied to music and the creator economy. Backing the next generation beside him is the easiest decision I have made in venture.”

Said Keulen: “Willard has spent 25 years proving that backing creators and founders on fair terms builds real, lasting companies, and he started before Sweden even had a unicorn.
“Today, Stockholm produces more unicorns per capita than any city outside of Silicon Valley, with several of the biggest tied to music and the creator economy. Backing the next generation beside him is the easiest decision I have made in venture.”
Langer spent over a decade in media, entertainment, and finance, most recently as a Vice President in Lazard‘s Media, Entertainment & Sports group, where the firm says he helped build the group’s music M&A practice.
“It’s been incredible to work alongside Willard, an innovator in our industry, and build ACP with him the last few months,” said Langer. “We’re now looking forward to Isabel joining us today as we launch.
“We have a great team in place to support the next wave of music and media technology companies.”

ACP says one focus is helping international companies establish themselves in the United States and other key markets, with portfolio companies getting operational support on the ground in New York, plus introductions to US-based operators and advisers.
“Twice I have been out on the street in New York pitching my own start-up, so I know firsthand how hard it is to land on a new continent and build the operations and network from nothing,” said Ahdritz. “We will be hands-on with founders on the hard questions. To be big globally, you have to be big in the US.”
ACP arrives in a music-linked venture landscape that has thickened over the past 18 months.
In May 2025, Yamaha launched a USD $50 million corporate venture fund, the Yamaha Music Innovations Fund I, LP, headed by Managing Partner Andrew Kahn, with AI-powered creative tools among its stated investment areas.
In October 2025, UK PR company Jukebox launched Jukebox Ventures, targeting a raise of up to USD $15 million for early-stage bets from pre-seed to Series A.
Jukebox cited its own reasoning for the gap it was moving into, saying that “less than 10%” of music tech VC deals occur before Series A.
Matt Pincus‘ MUSIC has been investing in music companies since 2019, and raised USD $200 million in 2022 to take positions across technology, labels and publishers, and Web3.
MUSIC was also a minority shareholder in Kobalt alongside Ahdritz before the Primary Wave sale, with Pincus taking a seat on the board.
Much of the recent capital flowing into music technology has gone to AI companies. ElevenLabs, Hook, Just 4 Noise, Mozart AI, and Tamber all raised in the first half of 2026 alone.
As MBW reported in May, much of that activity has centered on generative platforms that produce finished audio, rather than on tools built to sit inside existing creative workflows.
ACP‘s stated targets – media infrastructure and systems, plus fandom and audience platforms – sit on the infrastructure side of that line, which is also where Ahdritz built Kobalt.Music Business Worldwide
