The investment from Sir Terry Leahy and William Currie Group will fund product development and international expansion.
£2.0MSeries A
Sirenum provides cloud-based workforce management technology for employers of complex and shift-based workforces. The platform helps organisations manage schedules, payroll, and compliance across multiple sectors.
Sirenum has secured £2m in a Series A funding round from former Tesco CEO Sir Terry Leahy and the William Currie Group. The capital will be deployed to support company growth, accelerate product development, and expand operations internationally. The transaction follows strong performance through the pandemic and heightened investor interest in human resources technology.
From the founder
"We’re thankful to our investors for their continued support and for seeing the vision we have for Sirenum in the future. Our continued growth across a variety of industries, as well as new use cases that could not have been foreseen, such as that created by the new vaccination centres, highlight the unique proposition we offer. Moreover, we believe the flexibility of the platform to adjust to unpredictable scenarios, i.e the ability to manage rosters and staff shifts in real time and adjust for sickness or the need to isolate, further underlines why there has never been a better time to invest in workforce management technology like ours. The pandemic has expedited the need for businesses to embrace technology across various parts of their operation, but it is the commercial opportunity for staffing agencies and other employers of shift workers looking for a competitive advantage that will truly propel the use of our technology in the future."
