The new office will initially focus on delivering an integrated end-to-end TMT practice for domestic and international clients, with further service lines expected to be added in response to client demand, the firm said.

The office has been founded by a four-strong partner-led team of respected contentious and non-contentious lawyers with extensive experience advising start-ups, investors, tech multi-nationals, and global brands on IP, technology/sourcing, data privacy and digital transformation matters.

Two of the four founding partners, Jeanne Kelly and Ciarán Markey, joined the firm recently and are permanently based in the Dublin office. The other two founding partners, Declan Cushley and Anthony Nagle, originally from Derry and Kerry respectively, put in place the strategy to open in Dublin.

Mr Cushley is the head of the firm’s commercial and technology group and Mr Nagle is the national head of technology, outsourcing and digital transformation based in London. Both Mr Cushley and Mr Nagle will be dividing their attention between London and Dublin.

The team has also appointed Mike Rebeiro, former head of TMT at Macfarlanes, as the firm’s TMT and digital transformation consultant and added senior associate Darragh Killeen and associate Raymond Sherry.

The Dublin-based team is working closely with the firm’s 40-strong UK-based team to support existing clients in the TMT space while attracting premium domestic and international mandates.

Welcoming the firm’s launch, Tánaiste Leo Varadkar said: “I am really pleased that Browne Jacobson has chosen Dublin for its first overseas office.

“Ireland is home to a lively and experienced legal services sector and Browne Jacobson’s plans for strategic growth in Ireland will offer wonderful employment opportunities for our legal and business service professionals.’’

In a joint statement, Ms Kelly and Mr Markey said: “Having our first overseas office in Ireland is a real game changer for us and our clients. It will ensure we are perfectly positioned to meet growing client demand for an integrated cross-border offering spanning three of the world’s primary tech hubs – London, Dublin and the US.

“As a firm we’re passionate about making sure our teams on the ground truly reflect the societies we serve. We have ambitious plans to grow our Dublin office over the next few years and will ensure that we take full advantage of the bounty of diverse talent available locally.”

Dónal Travers, head of technology, consumer and business services at IDA Ireland, added: ‘’IDA Ireland welcomes Browne Jacobson’s plans to grow its Irish legal team, having recently established its first overseas office in Dublin.

“The company is a welcome addition to Ireland’s vibrant and expanding legal services ecosystem and their growth plans signal confidence in the favourable conditions that exist here for companies in this sector, and for their clients in the technology, media and telecommunications sector.

“I wish them continued success with their expansion plans.”
