Finn Partners has acquired Dublin-based 360, a full-service integrated communications firm with 17 staffers.
Dan Pender, who launched the shop in 2011 after stints in Ireland's government, will become a managing partner of the revamped 360, a Finn Partners Co.
He called the deal "a milestone moment for our business" and the best way to advance 360's next phase of growth.
Pender is "excited to become part of a global firm that celebrates entrepreneurial spirit and creativity, with leadership that shares our vision of the role that communications plays in today's world."
He expects clients to benefit from access to expanded capabilities, including specialties such as global intelligence, integrated marketing, employer brand and ESG.
Pender reports to Chantal Bowman-Boyles, managing director of EMEA.
Peter Finn called Ireland an increasingly important market for global clients seeking to establish or grow a presence in the European Union.
He said the addition of 360 is strategically important for Finn Partners' continued growth.
Finn Partners has overseas offices in London, Paris, Munich, Frankfurt, Jerusalem, Hong Kong, Shanghai and Singapore.
It holds the No. 4 slot in O'Dwyer's rankings of independent firms with fee income of $109.9M in 2020.
