Galway, Ireland, 4th December  — Siren today announced that it had won the Scale Up award, sponsored by Scale Ireland and was ranked number 9 in the 2023 Deloitte Technology Fast 50 Awards. The Fast 50 is a ranking of the 50 fastest growing technology companies in Ireland. Rankings are based on average percentage revenue growth over four years. 

Siren’s CEO, John Randles, credits his team’s dedication to proactively solving law enforcement and public safety challenges with the company’s growth over the past four years. He said, “We’ve increased our domain expertise ten fold over the last four years by investing in industry talent and upskiling our existing team. This allows us to solve problems faster and empathises with our customers in a way we couldn’t before.” 

John added that “We’ve also ramped up the commercial side of SIren with internal talent and partnerships. This has dramatically improved our ability to communicate our value and with increased reach. We’ve always known we have a great product and now we can simply sell it better and much further afield.”

The Fast 50 awards are an important and exciting moment for Ireland’s indigenous tech industry to reflect on the growth and challenges they have experienced over the past year. Even though this has been a difficult year for tech companies, there are encouraging indicators in these rankings that show the strength of Ireland’s indigenous sector and that our homegrown talent continues to play an important role in building the future of technology.
