Revenues at Irish law firm Mason Hayes & Curran jumped 8% last year to €106 million.
It recorded particularly strong growth in financial services across structured finance, transactional work such as loan portfolio sales, and international and domestic financing.
The firm acted for clients such as Morgan Stanley, Goldman Sachs, Citibank, Allied Irish Banks and Bank of Ireland.
It said advisory work on financial services regulation also grew.
Mason Hayes & Curran said work in the technology sector also increased - being both advisory work for multinational technology companies, transactional work for Irish technology companies, and regulatory advice on investigations and litigation in the sector.
The firm advised clients such as Meta, Etsy, WhatsApp, Kinzen and Instagram across these areas.
Reflecting growing international workstreams, the firm's London and San Francisco offices both expanded to accommodate more staff, including the appointment of new heads for each office.
The firm also said it is reviewing its office accommodation options in Dublin, including either additional space to supplement its current location, or a new consolidated HQ location.
"During my nine years as Managing Partner, the firm has more than doubled in turnover and size," said Declan Black, in his last year as Managing Partner.
"The numbers are satisfying evidence that clients appreciate the quality and calibre of the work we do and that talented staff appreciate the opportunity we provide to develop and prosper," he added.
New Managing Partner, Will Carmody said the firm will continue to provide clients with "sure and trusted" legal advice, as they navigate an increasingly complex political and economic environment.
"We are very aware that the success of our business is completely aligned with the continued success of our clients - which incentivises us to protect and enhance their best interests at all times," he said.
