C3 Marketing opened its doors in Dublin in 2011, and set up its first international office in Leicester, UK, just two years later.
A significant factor behind C3’s success is that our sales packages generate real value for customers – some €6 million in full since we launched.
In 2014 we initiated the C3 Sales Academy, an original staff training scheme that gives new employees hands-on skills in four disciplines, including direct sales and team leadership.

We are proud recipients of support and funding from Enterprise Ireland

3 reasons why C3 is passionate about direct sales:

Face to face is more effective than
other low-cost marketing methods.

Direct sales generates
quality leads, proven to be a key
priority for businesses.

Direct sales is targeted, which
is 6 times more effective than
other campaign factors such
as creativity or timing.
