Calculus Capital has invested £2m in Rotageek alongside Mobeus, which first invested in Rotageek in 2018, in a £6 million new investment round, alongside angel investors.


Rotageek uses cloud-based technology and automatic scheduling to help multi-site businesses manage and schedule staff to meet demand, drive efficiency and reduce costs. The tool uses machine learning to identify patterns which may otherwise go unnoticed and its apps make it easier for staff to swap and cover shifts and know when they are working.

Rotageek has established a strong position in the UK retail sector, working with High Street names such as Prêt a Manger, The Perfume Shop, Dune, Pets at Home and O2.

The Company was founded by the current CEO Dr Chris McCullough, CTO Nick Mann and Professor Roy Pounder. Chris trained as a medical doctor spending 16 years in the NHS and 8 years as an Emergency Medicine Physician, at several London based hospitals, including St Mary’s Hospital. The difficulties of managing a shift-based, lean work force provided Chris with the motivation to establish Rotageek, utilising Nick’s technological ability to create a relevant solution.


Rotageek has a strong management team and impressive technology, which delivers significant measurable returns for clients. The company has a strong client base in its core sector and is poised to expand into the global workforce management market, which is valued at over £3bn. The service is also expanding to healthcare. During the COVID-19 pandemic in 2020 the company offered a three month free trial of the software to the NHS and wider healthcare teams impacted. The offer attracted significant interest from NHS hospitals and Trusts and was implemented across hospitals nationwide
