Ireland has long been a fertile ground for innovation, entrepreneurship and bold thinking but now more than ever, it’s time to shine a spotlight on the next generation of game-changers. The Business Post’s Hot 100 Start-Ups supplement celebrates the energy, creativity and resilience of Ireland’s emerging businesses. These companies are not just shaping industries — they are fuelling economic growth, creating jobs and transforming local communities.

From Mayo-based payroll software business Payslip, which was started by Fidelma McGuirk and has to date raised €12.4 million, to cloud software business Greyscout which raised €3.5 million in seed funding last year, these companies are among the greatest in fresh thinking and dynamic business leadership on display here in Ireland.

In conjunction with our partners in Enterprise Ireland, the Business Post is delighted to celebrate the best in Irish ingenuity, entrepreneurship and endeavour. Start-ups are the lifeblood of a vibrant economy. They bring fresh ideas, disrupt traditional models, and challenge established players. From tech innovators to sustainability pioneers, the Hot 100 Start-Ups represent the best of what Ireland has to offer.

By highlighting their stories, we’re championing the brave entrepreneurs who dare to build something new, who see opportunities where others see obstacles.

But it’s more than just celebrating success; it’s about fostering a culture of innovation and inspiration. When we spotlight these start-ups, we encourage the next wave of founders to follow their dreams and push the boundaries. We show that Ireland is a dynamic hub for start-up activity, attracting investment, talent, and global attention.

This list is not just a testament to hard work and ingenuity — it’s a glimpse into the future of business. These 100 companies are the ones to watch, and we’re proud to champion them in our supplement. We hope you enjoy our list.
