Revenue from Irish businesses in which Dutch private equity group Waterland has invested have hit €350m.
The company has partnered with 18 firms over the last three years, increasing revenues from Irish operations by €270m.
The investments are across a variety of sectors including healthcare, engineering and manufacturing.
In 2019 it bought nursing home operator, Silver Stream, and since then it has added four more homes, bringing the total number across the country to 11.
Two years ago it took a majority stake in Westmeath-based fire protection company, Writech Group.
In the last 12 months it has also invested in MTM Engineering, a Meath based provider of data centre cabling, which in recent months bought CET Connect and ATSS Ventures Ltd, which provide structured cabling and fibre optic services.
WTech Fire Group, which is part of Writech, recently bought SRS Alert Fire, which provides life safety solutions to a variety of business.
The acquisition is expected to add €10m to Writech's revenues.
"Our team is delighted to reach this key milestone of surpassing €350 million in revenue generated through our partnerships," said Laura Dillon, Partner at Waterland Private Equity Ireland.
"Waterland's partnership model is rooted in fostering long-term collaboration and supporting the entrepreneurial spirit within each company."
"By providing strategic guidance, operational expertise, and access to a vast network of resources, Waterland has enabled its partners to accelerate their growth trajectories, achieve operational excellence, and capitalize on market opportunities."
Waterland opened an office in Ireland in 2019 and helps established businesses to dramatically accelerate their expansion plans.
It typically invests in companies making between €4m and €100m in earnings, focusing in particular on partnering with businesses related to the ageing population, outsourcing, digitalisation, sustainability, leisure and luxury.
The number of people working for Waterland companies has increased by 1,000 following its acquisitions here and the creation of 700 new positions, and its firms now employ 2,000 people in total.
Earlier this year it launched its ninth institutional fund, the €3.5bn Waterland Private Equity Fund IX.
This is alongside the €500m Waterland Partnership Fund I, which was received investment from the Ireland Strategic Investment Fund (ISIF).
