Meet the integration experts

NextGenOpX is led by a talented team of world-leading experts in integrated operations, strategic thinking and transformation.

The right team for the job

Our team all have a deep operating understanding of their field, excellent technical skills, strong operational empathy and demonstrated results in leadership roles. Many have been senior executives in major companies.

We also have partnerships in place with specialist solution providers and consultancies in Africa, and excellent relationships with senior executives, technical institutions and services providers across many different industries.

We regularly augment our team with experts hand-picked to tackle a particular problem, many of whom have moved into independent consulting after a long career at the top of their game in the corporate world.

Our approach is to always select the best people for the job, to deliver outstanding value to our clients.

'The corporate world is often a frustrating place to work, full of politics, bureaucracy and misaligned systems and processes.  What I love about NextGenOpX is that now I can focus on the work I really enjoy, which is leading organisations through real transformation and re-invention to position themselves ahead of their competitors with a team of great people.'
