Company: Kelsius
Industry: Temperature Monitoring & Compliance Technology
Location: Donegal, Ireland

Founded in 2002, Kelsius has grown from a R&D-focused startup into one of Europe’s leading providers of wireless temperature monitoring and digital compliance systems. Today, the company designs, manufactures, installs, and supports its own hardware and software solutions, serving customers globally across healthcare, pharmaceuticals, food retail, and hospitality.

At the core of Kelsius’ offering is its data-driven platform, enabling organisations to monitor and safeguard temperature-sensitive products such as food, blood, and medicines, helping ensure safety, compliance, and operational efficiency.

Like many companies in the West of Ireland, access to early-stage capital and support for international scaling played an important role in unlocking Kelsius’ growth potential.

The Western Development Commission has supported Kelsius at two key stages of its development:

  • Early-stage support: An initial equity investment helped the company evolve from a research-led operation into a commercially focused business.
  • Growth-stage funding: More recently, WDC provided a loan facility to support the next phase of Kelsius’ global expansion strategy.

The Western Development Commission were an early supporter of Kelsius’ by taking an equity stake in the business and providing that early financing to get the business off the ground. Now, 22 years later they're here again with us to fund the next stage of our global growth strategy and providing a loan facility to do so

Scaling for Global Success

Kelsius has built a fully integrated offering, from manufacturing hardware to delivering data-driven services, and holds ISO 9001 and ISO 14001 accreditation. Today, the company operates in 47 international markets, with 75,000 sensors deployed worldwide across hospitals, blood banks, pharmaceutical manufacturers, and food businesses. It employs a strong team of over 100 people based in Donegal and is positioned for continued growth across Europe, the Middle East, and North America.

The company is actively expanding its presence in key European markets, including Spain, France, Germany, the Netherlands, and Italy, while also entering the UAE, Saudi Arabia, and North America.

Kelsius has also attracted skilled professionals to the region, combining quality of life with the opportunity to work on cutting-edge technology while supporting regional employment. As Dominic Shannon, Chief Operations Officer, explains: “We’ve been able to build a strong team with deep expertise. People are drawn here for the lifestyle, but you’d be surprised by the level of talent in the area.”

Today, a team of over 100 people in Donegal supports customers around the world, demonstrating how high-value, export-driven businesses can successfully scale from the West of Ireland.
