In recent times, 17 jobs were filled at Augentius' new Belfast base and this is expected to grow to 30 by the end of the year.
David Bailey, Managing Partner of the firm, said it has "a strong reputation for the development of its staff."
He said: "We take junior and part qualified accountants, train them in our sector and support them to obtain their professional qualifications. We have people who joined us as trainees and are now fully qualified accountants responsible for their own teams and clients and I am very proud of this achievement."
"As a consequence, the availability of high quality people along with a strong educational sector was one of the important factors to us when considering the locations for our investment and we are looking forward to working with Queen's University and the University of Ulster going forward."
Enterprise Minister Arlene Foster said: "This investment, the first ever from a London based fund administration company, is a significant milestone in the development of the financial services sector in Northern Ireland.
