About Infinity

Hi, I'm Cathy. I set up Infinity to give growing businesses the marketing experience they deserve.

Marketing leader, qualified copywriter and founder of Infinity Marketing, based in Kildare.

Cathy Gilmartin

My story

I've spent over 20 years in marketing, in multinational businesses and in fast growing technology companies.

Most recently I was Head of Marketing in an IT channel business, working with partners including Microsoft, Dell and Fortinet. I ran partner campaigns, worked with distributors to fund them, and built a marketing function that supported the sales team every day. In 2024, Fortinet named me their Marketeer of the Year.

Along the way I've led company rebrands and growth strategies, two of which played a part in successful acquisitions. I'm a qualified copywriter, and I recently completed a Postgraduate Certificate in Digital Leadership and Transformation at TU Dublin.

Why I started Infinity

Larger businesses have marketing leaders who set the direction and make sure the work gets done. Most growing businesses don't. They have good people doing marketing in between everything else, or an agency doing tasks without anyone senior joining the dots.

I started Infinity to close that gap. You get senior marketing experience, and the hands on work to go with it, sized to your business.
