StormHarvester has been announced as the fastest growing technology company in this year’s Deloitte Technology Fast 50 Awards at a ceremony in the Mansion House in Dublin this evening. StormHarvester uses its advanced anomaly detection system to analyse data from thousands of sensors to help wastewater utilities predict and prevent issues like flooding and pollution.
The Deloitte Technology Fast 50 Awards, now in its 26th year, is one of Ireland’s foremost technology award programmes. It is a ranking of the country’s 50 fastest-growing technology companies based on revenue growth over a four-year period. Previous winners include Wayflyer and Swoop.
Reacting to the win, Brian Moloney, founder and CEO of StormHarvester, said:
“Achieving the top spot in Deloitte’s Fast 50 ranking is a really special moment for all the team at StormHarvester. What started as an idea over ten years ago in Australia for a solution that would reduce the impact of flooding has grown into a proud Belfast-based business that is going from strength to strength. In the last year alone, our funding has enabled us to double our headcount, which will help us fuel our expansion further and create even more exciting opportunities in Ireland.
“The Deloitte Fast 50 Awards recognition is a chance to pause, reflect and celebrate all that we have achieved and all that we plan to achieve in the years ahead.”
Cumulatively, the Deloitte 2025 Technology Fast 50 winners generated €1.76 billion in total annual revenues. The average growth rate of the companies was 442%. The 50 companies employ over 7,500 people and 12 of the ranked companies were first time winners.
Announcing the winners of the programme, James Toomey, partner and Fast 50 lead, Deloitte Ireland said:
“For 26 years, the Deloitte Technology Fast 50 Awards have been a benchmark for Ireland’s most ambitious tech entrepreneurs. The combined €1.76 billion in revenues generated by these 50 indigenous companies is a powerful symbol of the exceptional talent and innovative thinkers we have in Ireland. Despite a challenging external environment, Fast 50 companies are still growing, which is a real signal of confidence.
“A standout from this year’s awards is that companies with Artificial Intelligence (AI) embedded in their operations are seeing the biggest growth, but access to skilled employees who can prompt and deploy AI effectively will be crucial.
“The Deloitte Technology Fast 50 is a rigorous, data-driven ranking that provides a trusted measure of success and growth. Congratulations to all the companies that ranked; your grit, resilience and creativity are truly inspiring. I would like to extend a special congratulations to StormHarvester for securing the top spot in this year’s rankings.”
In addition to announcing the ranking of the Fast 50 companies, the Deloitte Technology Fast 50 Awards included several award categories.
Protex AI, which uses AI to enhance workplace safety and operational efficiencies, won the Rising Star Award in association with Enterprise Ireland, having demonstrated a promising growth trajectory and the potential for inclusion in the Fast 50 rankings in years to come.

“Since founding Protex AI, our mission has been to enable organisations to use data-driven insights to drive safer workplaces and unlock meaningful operational efficiencies.
