Kieran Mahon, DesignChief · Brand designer, Dublin

I’m Kieran Mahon. DesignChief is my brand design studio in Dublin.
I work with founders, leadership teams and in-house brand leads as a design partner, on the brand itself and everything it touches: identity, websites and the digital tools a business runs on.
You work with me directly, from strategy through design and build, as part of your team.
We start with the bigger picture: who you’re talking to, how you’ll sound and where the brand needs to go.
Strong brands rest on simple, well-tested ideas. I shape one that works everywhere it needs to.
I design and build the websites, web apps and custom tools your business runs on, down to the last detail.
Your brand’s rules, assets and principles, organised for your team and the tools they work with.
Once a brand is in use, new situations come up. I stay involved and keep developing it for as long as that’s useful.
Who you’ll work with, where I’m based and how a project runs.
With me, Kieran Mahon, from the first brief through design, build and launch. DesignChief is my studio, so there’s no account manager in between. When a project needs something outside my own work, I bring in a specialist. For photography, I work with my wife, Michelle O’Sullivan of MOS Photography, a portrait photographer specialising in newborn and family work, who also shoots commercial and team photography for my projects.
DesignChief is based in Dublin, Ireland. I work with clients across Ireland and abroad, including in the US, and projects run just as well remotely.
Founders, leadership teams and in-house brand leads, from new businesses starting with a blank sheet to established companies in property, finance, healthcare, food and technology. What they share is a brand that has to work hard across print, packaging, websites and the tools their teams use every day.
It starts with your enquiry. Once we’ve agreed the scope, I set a clear direction with you: who you’re talking to, how you’ll sound and where the brand needs to go. Then I design and, where the project includes it, build, with rounds of feedback along the way. You finish with the files, guidelines and, for a website, a live site your team can manage.
Yes, where it helps. I use AI-assisted tools and workflows alongside my own design and development work, and the design judgement stays with me. I also build BrandChief, so your team’s AI tools can work from your approved brand rather than guessing at it.
Tell me about the brand and what’s next for it.
