'An important step in our journey': Northern Ireland software firm opens new Belfast headquarters as global expansion continues

Northern Ireland software firm StormHarvester has officially opened its new headquarters in Belfast, marking a major milestone in the company’s continued growth and supporting its expansion into international markets, including Australia and New Zealand. The new headquarters at 10 Mays Meadow was opened by Lord Mayor of Belfast, councillor Tracy Kelly and will serve as the central hub for StormHarvester’s operations, supporting its 100-strong team and strengthening its ability to deliver services to customers across the UK and globally.

StormHarvester helps wastewater utilities predict and prevent issues like flooding and pollution before they happen, protecting communities and reducing costs. Their advanced anomaly detection system analyses data from thousands of sensors, turning it into precise, actionable insights that drive smarter decisions in utilities. The company has a dominant position in the industry, working with almost all wastewater utilities in the UK and Ireland, and also has a growing presence in Australia and New Zealand.

This move reflects StormHarvester’s rapid development and commitment to scaling its operations. The new space has been designed to support collaboration, innovation and future recruitment, positioning the business strongly for continued growth.

That growth has been reinforced by recent achievements including being ranked number one in the Deloitte 2025 Technology Fast 50 having doubled its headcount throughout 2025. The company’s recent expansion has been largely fuelled by a successful 'Series A' investment round in early 2025 and has also received funding from Invest Northern Ireland and Techstart Ventures, which have been key to its success over the past nine years. Brian Moloney, founder and chief executive officer said: “Opening our new headquarters in Belfast represents an important step in our journey. As we continue to grow, this new base gives us the space and infrastructure needed to support our team and deliver even greater value to our clients, both in the UK and globally.” Kieran Donoghue, chief executive officer of Invest NI added: “Invest NI’s relationship with StormHarvester goes back almost 10 years. We are proud of the work we have done together to support the company to innovate, develop its product offering and grow the team and overall capabilities.

"I wish Brian and everyone at StormHarvester continued success as they use this new office to implement their strategy and deliver industry leading solutions to clients around the world.”
