(MENAFN- PRovoke) LONDON - Agency collective Stakked has acquired established digital specialist Radioactive PR, just 12 months after it was founded.

Radioactive, which was founded in Gloucester, UK, by Rich Leigh 11 years ago, will merge with Munch, Stakked's consumer PR agency. The Radioactive name will be retired as the team and clients transition to Munch, with Leigh joining Munch as a non-executive director. There will be no redundancies.

The acquisition will double Munch's revenue and headcount, and takes Stakked's headcount to over 20, as well as expanding its digital expertise and introducing a creative B2B offer to Stakked clients. It also adds a new office outside London.

Radioactive PR has worked with start-ups and big brands on digital PR, creative stunts, influencer campaigns and SEO content strategy, including Paddy Power, Virgin Media, GoCompare and the National Gallery. The agency's charity work has also helped to raise more than £1m for children's charities such as Great Ormond Street Hospital.

Stakked was founded in 2024 by Lizzie Earl, with backing from agency veteran Andrew Bloch, who sits as non-executive chairman. The collective brings together specialist“boutech” agencies across earned, social, paid and digital: as well as Munch, these are social agency Flabbergast, full-suite digital agency Another Blank Page, and Nibble, an AI-powered SaaS platform that matches brands and agencies with pre-vetted freelance PR and creative talent.

Earlier this year, Stakked was named as PRovoke Media's Agency of the Future and as one of the six best new agencies in EMEA . Earl was also named as one of the Innovator 25 for EMEA last year.

Earl (pictured, centre) said:“This move is about doubling down on specialism. We believe the future belongs to boutique agencies that go deep, not broad, and bringing in Radioactive's strengths in B2B, SEO-led content, high-authority link-building and digital-first creative adds another layer of impact to what we do. It will allow us to cut through even further, driving results across traditional search, domain authority, traffic, and the increasingly important world of AI-powered discovery.

“We've always admired the team's bold thinking, challenger energy and relentless focus on results – it's exactly how we operate. Pairing that with our creative firepower and proprietary AI tools, which streamline workflows and deliver campaigns with extra precision, puts us in the perfect position to take on bigger briefs and keep punching well above our weight.”

Leigh (pictured, left) said Munch was“a perfect fit” for Radioactive's team and clients:“Every conversation with Lizzie and Andrew has only further cemented my opinion that they're building something special. Our success over the last ten and a half years, working with more than 300 clients, has been based on our core values of ambition, accountability and creativity – values Lizzie and the group clearly share.

“Being part of a forward-thinking, tech-led group like Stakked gives our team and clients access to a broader set of skills and integrated expertise. Together with Munch, we're not only able to think bigger but deliver bigger too, without losing the punchy, entrepreneurial edge that's defined us.”

Bloch (pictured, right) added that the ambitious agency collective was on the hunt for further acquisitions:“This is just the start for Stakked. We're building a group of the sharpest, smartest agencies in the industry, agile enough to move fast, but experienced enough to deliver world-class PR and marketing, and are on the hunt for other ambitious and specialist founder-run agencies across earned, social, paid and digital who'd like to be a part of what we are building.”
