In a small to medium enterprise success often comes down to a single business decision. Access to the top-level expertise needed at critical inflection points is often too costly or requires long term commitment – but this can be the difference between stagnation and growth.
Our four founders saw this too often when providing advice, executing strategies and transforming operations at large corporations.  We saw the impact of poor business decisions and inability to adapt to changing market conditions.  Cognisium springs from this experience.

Our freelance global executive marketplace is powered by our unique technology platform, developed in Israel.  Cognisium’s HQ and support centre are located in Australia, and we have a satellite office in Dubai.

For our freelance expert executives, the Cognisium platform enables you to bring your knowledge to new and exciting challenges and industries with flexible earnings, without the commitment of a full time role.

Our approach gives you the freedom to focus on family or pursuits that may have taken a back seat whilst working full time to build your career.

For our Experts

We built Cognisium to help small to medium enterprises access the brightest top executives quickly, efficiently and at a competitive rate in order to support their growth and aspirations.


We shift the paradigm of full time executives on the payroll to a more flexible and agile way of doing business.

Our Experts bring a strong desire to share their expertise with you and support your business through critical inflection points. And who better than you, knows where or for how long this expertise is needed?

For our Clients

We provide a knowledge sharing community, bringing together Experts and Clients in an affordable and flexible way so that you can adapt to the ever-changing business climate.
