Support for a new business

I am an experienced public servant with particular interest in marketing and public relations. Looking to work with a new or developing business to realise new opportunities, etc

Where could I link with entrepreneurs located in Dublin or surrounding counties ?

You could speak to Enterprise Ireland with a view to becoming a mentor but it's a very busy space you are looking at.
Is there a particular area in which you have worked (agri-food, life sciences, engineering, ITC etc)?
You have to be able to pitch what you have to offer. You may be able to help businesses who want to work with this or other governments or state bodies. For those of us who work exclusively in the private sector the thoughts of trying to interact with officialdom fills us with dread!

Best of luck.

Interesting perspective there. Appreciated
