Carmel Owens

Carmel Owens - Chief Executive Officer (CEO)

"Delivering always is our mantra at Sidero. I’ve worked in senior roles in both large and small companies so I understand how to marry the sleeves rolled-up mentality of a small business with the scale and ambition of a larger one. I consider myself to be a pretty hands-on CEO. I’m not that far removed from the day-to-day running of the business that I won’t pick up the phone to customers myself! After all, it’s only by listening to them that we know our plans are heading in the right direction. That personal touch is one of the qualities that sets us apart from other software companies."
