Sirenum helps organisations meet the evolving needs of the rapidly expanding dynamic workforce by putting the right person in the right place at the right time and paying the right amount. Our technology leverages mobile and the cloud to streamline the management of part-time, temporary, and hourly workers.

Built from the ground up to handle the complexity common to temporary staffing agencies, Sirenum is also well suited to help employers in complex work environments like transport, care, construction, and security. Sirenum helps these organisations in scheduling shifts, monitoring staff, and processing key financial processes including payroll.

With Sirenum, employers drastically reduce costs while growing revenue, increasing staff utilisation and improving health and safety.

Our Story

Before founding Sirenum, Benjamin Rubin and his wife were managing a staffing agency focused on the rail sector in North London. They saw first-hand how hard it was to manage staff in a highly complex work environment. Over the years, they recognised the value that technology could provide in some parts of the process and saw tremendous growth with the adoption of tools for automating the recruitment process. But while their experience made clear the potential for technology to improve staffing performance, it also identified some key gaps in the market. Sirenum was founded in late 2013 based on that hands-on experience to build technology to address those gaps and the company began adding staffing and rail clients immediately.

Since then we’ve moved into other industries and geographies. Our team has developed Sirenum feature by feature, improving with every new challenge and learning from each mistake. The Sirenum platform is now used to manage more than 400,000 workers across tens of thousands of sites around the globe and is adding thousands of workers every month.
