Our Companies

Cello Health

Cello Health’s mission is to help our clients unlock the potential that exists with their assets, brands and organisations in a changing and challenging environment.

Cello Health provides our clients with access to expertise, processes, IP and market knowledge spanning the pharmaceutical, biotechnology, diagnostics, healthcare equipment and consumer health sectors.

We offer our clients the best of both worlds: working with leading edge professionals who have extensive experience in their specialist field; and where appropriate a blended team spanning multiple capabilities.

In addition to their pure health capabilities, The Value Engineers, Breaking Blue and Kudos also offer brand strategy and research services across a wider range of industry sectors.

Cello Signal

Cello Signal is a technology savvy marketing communications business that constantly seeks to push the boundaries of best marketing practice on behalf of our clients.

Our value to clients is founded on our ability to explore, understand and respond to the trends that are shaping both business and wider society.

We focus primarily on three aspects of marketing which are evolving most rapidly in the face of globalisation and digitisation: insight gathering; strategic and creative thinking; and the application of technology.

By continually adapting and evolving our agency model to keep abreast of the changing market, our specialist consultancies have become established as leaders in their field.
