Accenture

Accenture is a global consulting and IT services firm, and Ireland’s largest company. Its services are roughly evenly split between managed IT and consulting, encompassing digital transformation, cloud computing, data analytics, design and marketing (under the brand Song), digital engineering and manufacturing (Industry X), cybersecurity and AI projects—a breadth that allows Accenture to deliver what it calls "360 degree value." The Dublin-headquartered group, which originated from the business and technology consulting arm of U.S. former "Big Five" accountancy firm Arthur Anderson in the early 1950s, has 774,000 employees around the world. Accenture's largest sources of revenue come from North America and the EMEA.
