What I enjoy most about working with Kieran is his ‘ownership mindset’ no matter how small or complex the project is. He is all about quality and delivering value in collaborations. And he knows his stuff, you’ll see that in the first meeting.

Kieran is an outstanding writer and a pleasure to work with. Having him on board has made an enormous difference to our company’s marketing. He’s worked with us on copy, scripts, and presentations, and always provides the exact language our (highly technical) product requires. As a freelancer, Kieran provided a service that entire agencies struggled to.

Kieran is an exemplary communicator and storyteller. He helped lead the project’s content marketing and brand development efforts, writing and editing content, web copy, and guidelines. He was able to create a powerful brand voice for a complex project, remain focused within a challenging environment, and capture the essence – the reason and benefits – of abstract and highly technical products. I believe he’d make an immediate difference to any project. He instinctively understands the language and the reasons why, and is able to convey those reasons succinctly and compellingly to a global audience.

Kieran is a professional of many talents. He was instrumental in building our brand vision, tone of voice and narrative. Kieran works tirelessly and is not satisfied with anything but near perfection. He turns any jargon heavy technical material into an easy to comprehend copy. Kieran’s sense of audience is flawless evidenced by the narratives he developed for each segment. It was my immense pleasure to work with Kieran and witness his work ethics.

Kieran will be sorely missed from our team - he has a passion and care for his work that is hard to come by, and seeks to obtain a deep understanding of a given subject matter. He is able to work with the most loose of briefs along with changing source material and turn this into something that feels organised, concise and easy to understand as a reader. On top of that, he is a thoroughly nice chap who is a pleasure to work with and would be a great addition to any team.

I had the pleasure of working with Kieran Costello for many months - he is a great human being and an excellent content & communications lead. He is always knowledgable both about what is going in the industry as well as internally, and will use his many skills to bring even the most complex topics to the public in an engaging way.

Constantly ideating, creating and managing content releases, providing internal as well as external communication and education have proven very helpful. His input on product, UX/UI, design and structure across many forms of content were invaluable.

To sum it up, it has been a great pleasure working alongside Kieran, and I hope to do so again in the future.

Having Kieran as a manager is a pleasure. So far, we have worked together for a year. He is an excellent writer, whose input and guidance has made me into a better writer. He is the only writer in the crypto world that has actually improved my writing style. Added to that, his feedback was always delivered in a fair, helpful, and collaborative way; while he was good at delegating, he did not leave me wondering where, perhaps, I had made a mistake, but instead offered guidance and explanation. It has been a pleasure to work under him, and my work has become better, my time management superior, and attention to detail improved underneath him. As part of the broader team, I always appreciated his role as a manager, which is natural role for him.

He is a diligent organizer, and always let me know of my responsibilities clearly, and comprehensively. From working on Litepapers, blogs, websites, and video scripts with Kieran, I always learnt something new; his experience in the space makes him a valuable and rare writer of quality in the world of Web 3.0.

We’ve been using Upwork / Elance for for almost 10 years and I believe I can safely say that Kieran has been our best collaboration so far. He is extremely easy to work with, needs very little direction, completes his tasks on time and the quality of his work is 1st class. We will definitely be working with Kieran again!

Kieran has played an integral role in establishing a mature tone-of-voice across my marketing content. His natural ability to deliver content – rich in ideas and supported by informed thinking – continue to add value to my business. Kieran is a pleasure to work with – and I wouldn’t hesitate to recommend his services.
— David Fraser
I was very very happy with the content that was written for my homepage for my new business. I will definitely be using Kieran again for my other content requirements. He met the guidelines, was within the time frame and had excellent communication. Highly recommended
— Karen Thomas
Kieran always delivers above and beyond what is expected. He is definitely one of the best freelancers I’ve worked with.
— Garry Airiants
I was really happy with Kieran’s editing, and will definitely hire him again. In terms of proof reading, he is very detail oriented and thorough. In terms of ghost-writing, his suggestions and changes were EXTREMELY helpful. First of all, he’s a great writer who added a lot of punch without changing the style of the work. He pointed out many character and plot inconsistencies, and offered great suggestions on how to improve parts that were unclear to the reader. I also really liked how he was able to catch extraneous prose, the message of which had already been implied to the reader. I feel like his edits really helped my work. Thanks Kieran!
— Karina Vertlib
It was a true pleasure to work with Kieran. From the first contact throughout the entire editing work, he was just amazing and turned everything around in less than 72 hours. Very impressive and we’ll definitely work with him again!
