ABOUT NESSA
Senior judgement at every stage. Practical delivery built around your business.
I’m Nessa O’Brien, founder of OBC Marketing. I bring more than 30 years of marketing and business consulting experience across Ireland, Europe and the US.
Today, I combine that commercial judgement with practical AI and automation, helping SMEs make better marketing decisions and build systems they can realistically operate and sustain.
Most businesses don't have a marketing problem. They have a clarity problem.
Sometimes the answer is a better message, offer or campaign. Sometimes it is a system that makes sure the work actually gets done. OBC helps you identify which - and implement it properly.
Strategic marketing remains the foundation. AI simply helps deliver it better.
We combine traditional marketing expertise with practical AI tools to help businesses plan better, create faster, and execute more efficiently—without losing control, quality, or brand integrity.
