Ex-Tesco CEO invests £2M in UK-based platform that helps employers manage shift-based workforce


Sirenum, a work management platform that manages the shift-based workforce, has secured £2 million in its latest round from former Tesco CEO Sir Terry Leahy alongside the William Currie Group. 

The funding will be used to drive the company’s growth and further international expansion, as well as accelerating new product development.

“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 underline 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.” Said Benjamin Rubin, CEO, and founder of Sirenum.

Helping employers in complex work environments

Founded by Ben Hizak, Benjamin Rubin, and Joshua Pines in 2013, Sirenum helps organisations better manage their hourly workers. With the cloud-based platform, the company wants to put the right person in the right place at the right time with the right amount.

The company works with various industries such as staffing, transportation, construction, hospitality, healthcare, and logistics and is ideally placed to capitalise on this trend. 

Sirenum’s solution helps companies to simplify the process of managing shift workers, including managing schedules, monitoring staff, and processing payroll and invoicing. Its clients include Randstad, Impellam, Manpower, and GI Group. 

Notably, Sirenum also powers workforce management for employers in sectors like government, utilities, transportation, and more, such as the Scottish government, FirstGroup, National Grid, and the NHS.

How Sirenum was born?

Back in 2009, Benjamin Rubin and his wife, who ran a staffing agency in London, received a call that one of his employees had been hit by a train, when they were on honeymoon in Mumbai, India. Then, Benjamin wanted to create a tool to deploy and manage their staff safely at multiple locations. And thus, the idea for Sirenum was conceived.

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.

“Sirenum has performed well during the pandemic exhibiting strong and sustainable growth. I am especially proud of our support for hospitals, vaccination centres, and volunteer organisations combating the pandemic. With the advent of the gig economy, there is no doubt Sirenum’s unique offering as a ‘gig technology platform’ with strong compliance features will make it key in the future for sectors like healthcare, logistics, and others.” Comments Sir Terry Leahy.
