“Callum is an incredibly talented copywriter and has been a real asset to our projects. He works quickly, diligently and with a strong understanding of the brief, while also taking the time to learn about the industry and audience he is writing for. 

One of the things I have valued most is his ability to adapt his tone and style depending on the project, whether the copy needs to be more technical, commercial or audience-led. He is reliable, thoughtful in his approach and easy to work with. I would highly recommend Callum to anyone looking for a skilled and versatile copywriter for their project.”

“Working with Callum has been a genuine pleasure from start to finish. He has a rare ability to get up to speed on even complex, technical topics quickly — which made collaboration feel effortless, rather than laborious.

Callum is approachable, responsive and always willing to go the extra mile, no matter the brief. It’s no surprise that the feedback from our team was overwhelmingly positive.

In an age where AI-generated content is everywhere, Callum’s writing is a breath of fresh air. His texts have a distinctly human quality: warm, natural, and genuinely enjoyable to read. That’s something no prompt can reliably replicate, and it makes his work stand out in all the right ways.”

“I’ve had the pleasure of working closely with Callum for the past two years, during which time he has been a true backbone of the copywriting team. He’s an excellent writer who consistently hits the mark, no matter the brief, combining creativity with clarity and commercial awareness. 

What really sets Callum apart, though, is his ability to step confidently into client-facing situations. Whether supporting meetings, events or ideation sessions, he brings real value through thoughtful contributions, clear communication and a calm, professional presence. 

He combines personality and charisma with a highly methodical approach to his work, which makes him a pleasure to collaborate with and someone clients genuinely trust. Callum is a brilliant asset to any team, and I’d happily recommend him to anyone looking for a writer who can operate at both a creative and strategic level.”

“Callum was a joy to work with. I thoroughly enjoyed reading the opening 20,000 words of his novel, and providing feedback. Callum’s writing style is refreshingly lean and evocative. His characters leap of the page and his world-building is very convincing. I look forward to reading his prose fiction in the near future and working with him again.”  

“Working with Callum was a joy! Not only is he a talented writer/editor, he’s a great teammate with a friendly and open demeanour. 

From social media copy to whitepapers, he handled every project with creativity, a can-do attitude and a willingness to throw himself in. He was able to adapt to his skills to a number of different clients we worked with across a many different industries, delivering high quality work. 

When working directly with clients, Callum offered sound advice and direction while openly taking feedback and applying this to the work. I had a great time working with Callum and would highly recommend him!”

“I’ve worked closely with Callum for a few years now, and he is honestly one of the best copywriters I’ve come across. He has a real gift for writing in a way that feels completely effortless, even when the subject matter is highly complex.

Beyond the work itself, Callum is an incredible teammate to have in your corner. He has a rare, intuitive instinct for the craft and doesn’t need a massive, in-depth brief to exceed client expectations on the very first draft. In an industry where things can often get frantic, he is remarkably level-headed and stays calm under pressure, which makes him a real anchor for the rest of the team. He’s also the first person to volunteer his time to help out a colleague who might be struggling with a project.

Clients absolutely love him, too. He has a natural, easy-going charm that builds trust instantly, and he knows how to communicate his ideas with a quiet confidence that puts everyone at ease. Overall, Callum is a top-tier writer; sharp, incredibly witty, and just an inspiring person to be around. He would be a massive asset to any marketing or creative team.”

“Callum is one of the best copywriters I’ve worked with in my career.

I originally hired him while running CopyHouse, a content marketing agency specialising in tech. Our job was to help complex companies communicate clearly with their audiences and Callum excelled at that from day one.

He consistently delivered high-quality work that hit the brief, captured the client’s tone of voice, and rarely required revisions, even from our toughest clients. Just as importantly, he brought a calm, can-do attitude to the fast-paced reality of agency life. He was reliable, adaptable, and always up for the challenge.

I’ve seen Callum handle everything from large-scale projects — including a 35,000-word book delivered in just 6 weeks — to sharp, conversion-focused email and social campaigns. His ability to switch between formats while staying true to brand guidelines and messaging is exceptional.

Over the course of my career, I’ve hired and managed more than 60 copywriters. Callum stands out as one of the very best. He combines strong strategic thinking with excellent execution, which is a rare combination in copywriting.

If you’re looking for a copywriter who can quickly understand your brand, write with clarity and precision, and consistently deliver work that makes clients happy, I’d recommend Callum without hesitation.”
