London-based Software Platform Helps Leading Global Agency Place Substitute Teacher in Just 31 Seconds

Sirenum, the leading global provider of cloud-based workforce management technology to temporary staffing agencies, is proud to announce the availability of F3 by Sirenum, the fastest way to place temporary workers. F3 allows recruitment consultants and operations professionals at staffing agencies to broadcast openings and get confirmations from workers faster than ever before. F3 is now generally available to all Sirenum clients along with a slew of new features also included in the 27 March release.

The launch of Fcoincides with the end of Sirenum’s best performing quarter to date. The company, which launched in 2013, secured agreements with three of the top 20 global agencies–including two of the top five–in the first three months of 2017. It also coincided with the launch of Sirenum at the largest of those agencies. Within one day of using the system, a substitute teacher was placed in just 31 seconds, an improvement of well over 1,000% over previous placements.

“We’re thrilled to bring F3 to the agency market,” said Benjamin Rubin, Sirenum’s CEO. “Prior to founding Sirenum, I spent nearly a decade in temp agencies, and nothing was more frustrating than the unnecessary delays of placing a temporary worker, especially in industries like education and transport. It impacts literally every person in the value chain–the agency, the workers and the clients. F3 is a revolutionary step for the industry that will transform the way agencies place and manage workers.”

Sirenum is in the process of rolling out F3 to its clients, and their excitement is palpable.

“We can’t wait to get our hands on F3,” said Tom O’Shea, COO of Pro-Active Recruitment, a longtime Sirenum client. “We’ve already gained a ton of efficiency from the Open Shift functionality and expect F3 to drive a similar boost.”

Other product updates in this Sirenum release include the latest version of MySirenum, Sirenum’s revolutionary mobile app for workers and managers, available from both the Google Play Store and the Apple App Store. In addition, the release includes improved functionality for the Sirenum scheduling engine, advances for the Open Shift function, and significant developments in Sirenum’s invoicing and payroll engine.
