"The demand for customer-focused, engaging websites and applications has grown exponentially in recent years and we’ve experienced significant growth on the back of this, consolidating our position as Ireland’s leading full-service digital agency," said Granite's CEO, Conor Buckley.

"Granite is pioneering the way forward when it comes to developing cloud solutions and digital transformation services in this country.
"The dedication and hard work of the team, particularly over the years of the recession has led them to the success of this major announcement today.
"Their story also goes to show how a world-class business such as Granite can grow from just a small base in rural Ireland to a large multi-national business trading in the capital city when the adequate infrastructure is provided to allow it to thrive."
