“We have found BCA to be an agency with a proven track record of developing digital campaigns and solutions that actually deliver meaningful results in shifting behaviour within complex and multi-dimensional areas, hence drawing them in again in an area such as mental health.”


Dr Lungi Nyathi, Managing Executive
“BCA has been instrumental in using behavioural communications to raise our digital profile in order to inform the public and key stakeholders about our activities, as well as mobilise access to educational opportunities for the youth of Mitchell's Plain and surrounds. As a public benefit organisation, it was critically important for us to partner with an agency capable of delivering expert guidance and excellent quality within exacting budgets.”

Our Case Studies

All case studies
In 2020 BCA was brought on board to implement a clear and effective multimedia campaign to raise the profile of the State of the Nation Address (SONA) and communicate its content and objectives on a broad scale. Our behaviourally informed approach ensured important Presidency messaging reached the SouthAfrican public on multiple digital platforms.

During the challenging first months of the coronavirus pandemic (March 2020 - October 2020), this resource also became a critical distribution point for COVID-19 information, helping to publicise and amplify vital announcements from President Cyril Ramaphosa. Through simple and salient digital assets and graphics distributed on a variety of government and social channels, BCA was able to reach and engage millions of South Africans and drive life-saving behaviour change.

Why is falling for fake news so easy despite all the warnings? Why do we carry high-interest debt even when we have the means to pay it off? Why are there so many browser tabs open on your screen right now even though digital clutter is so stressful?

At BCA, we mine insights from behavioural research to illuminate what really motivates human actions. Then, we add rigorous data analysis and a range of creative strategies to develop behavioural and communication solutions that improve decision-making and create better outcomes for customers, employees and citizens.
