Companies in Dublin

Medtronic's founding story is medical-device legend: in 1949, electrical engineer Earl Bakken started repairing medical equipment in a Minneapolis garage, and in 1957 — after a power outage disabled a hospital's bulky external pacemaker and a child died — he built the first battery-powered, wearable pacemaker using metronome circuits. That device launched the modern medical device industry, and the company he co-founded is now the world's largest. The product range spans nearly every medical specialty: cardiac devices (pacemakers, defibrillators, and the LINQ insertable monitors), diabetes management (insulin pumps and continuous glucose monitors), surgical robotics (the Hugo system), spinal and orthopedic implants, and minimally invasive surgical instruments. Medtronic's devices are used in virtually every hospital in the developed world, and its R&D budget of over US$2.5 billion a year keeps the pipeline full. Legally headquartered in Dublin (with operational headquarters in Minneapolis), Medtronic employs about 95,000 people and generates annual revenue near US$32 billion. Its scale makes it both the industry's benchmark and its consolidator — dozens of innovative startups have been absorbed into Medtronic's portfolio, a pattern that defines how medical technology reaches patients at scale.

CRH is the world's largest building materials company, headquartered in Dublin, Ireland, with origins tracing to 1936 when two Irish cement companies merged to form Cement Roadstone Holdings. The group employs about 75,000 people and generates annual revenue of roughly US$35 billion, operating in 29 countries across the Americas, Europe, and Asia-Pacific.\n\nCRH's business is built on the most basic inputs of construction: cement, aggregates, ready-mix concrete, and asphalt, produced and distributed through a vast network of quarries, plants, and terminals. Its North American operations, organized under the Oldcastle banner, make it the largest aggregate producer in the United States and a dominant supplier to infrastructure projects funded by federal highway programs. In Europe, CRH holds leading positions in Ireland, the UK, Germany, and the Benelux, and its Building Products division manufactures precast concrete, architectural glass, and fencing for residential and commercial construction.\n\nFor buyers and suppliers alike, CRH's scale matters: it consumes enormous volumes of mining equipment, trucking, and fuel, while its vertically integrated network — from quarry to paving crew — makes it a one-stop source for highway, airport, and building projects across the Atlantic.
