Slipstream Music Makes Senior Appointments Across Europe and North America as International Expansion Continues
Alex Mearns joins from Universal Production Music as Senior Director, U.K. Partnerships, alongside Jack London in U.S. Enterprise Sales.
New York, NY – August 10, 2026 – Slipstream Music, the world's largest production music licensing platform, has announced two senior appointments across its commercial and licensing teams as it continues to build out its international presence.
Alex Mearns joins as Senior Director, U.K. Partnerships, working with brands, agencies, and content teams across the U.K. and Europe to provide music for all of their content needs. Jack London joins as Director, Enterprise Sales, based in the U.S., focusing on direct relationships with brands and companies licensing music for their digital & social content.
The hires follow Slipstream’s acquisition of Megatrax earlier this year and come as the company scales its catalog of more than one million human-made production music tracks. Its proprietary licensing platform lets customers clear music at scale while removing the risk of copyright claims and takedowns — a growing concern for anyone producing content across today's fragmented media ecosystem, where usage rights differ across formats, platforms and territories.
"Slipstream has expanded rapidly over the past two years, both organically and through strategic acquisitions, and we're only really getting started," said Dan Demole, CEO of Slipstream Music. "Growth through acquisitions only holds if you bring in the right people to run with it. Alex and Jack are both proven, experienced operators in the markets we're operating in. I’m very pleased they’re joining us, and securing hires of their calibre is the clearest signal of where this company is headed."
Mearns joins after seven years at Universal Production Music, where he led partnership strategy and client activations with organisations including FIFA, Amazon Studios, Netflix, Warner Bros. Discovery, Banijay, the Premier League and the BBC.
The chance to help establish Slipstream's presence across the region was a key factor in Mearns joining. He said: "Slipstream has built something genuinely different for the production music industry. Bringing together more than one million human-made tracks with a modern licensing platform is a real opportunity for broadcasters, brands, agencies and creators across the U.K. and Europe, and I'm looking forward to introducing more people to what the platform can offer."
London joins from Artlist, where he was among the first hires in the company's New York office and helped drive its expansion in the U.S. market, working with enterprise brands, agencies and media companies on music licensing and creative solutions. London said: "After helping scale a fast-growing music technology company and working with some of the world's leading creative organizations, joining Slipstream felt like a natural next step. I'm looking forward to helping creators and brands tell meaningful stories through the power of music."
In addition to the new joiners, Joanna Gregory has been promoted to Vice President, Strategy & Operations at Cavendish and is reporting to JD Adams, Global Managing Director of Slipstream Music.
