Development Communication & Organisational Consultancy

Public purpose, private enterprise, and community voice — brought together.

THE SOCIAL MIX

Internal communication, stakeholder engagement, strategic events, and development programmes — built around your team and delivered end to end. We don’t manage logistics. We manage meaning.

The Social Mix is a strategic communications and development consultancy founded and led by Mareli Wassenaar, with over 30 years of experience working at the convergence of public sector strategy, cultural economy, and social development. We are a trusted implementation partner to national government, development finance institutions, and multilateral agencies — among them GTAC, National Treasury, the World Bank, UNDP, UNFPA, and SA Tourism — delivering end-to-end solutions across strategic events and conference management, development communication, stakeholder engagement, organisational communication, and cultural-economic placemaking. We take projects from inception to final implementation, managing complexity and protecting our clients’ reputations, across South Africa and beyond. Where others manage logistics, we manage meaning.
