Joseph Black
Co-Founder and Chief Executive Officer
SHOUT • UniTaskr
Joseph Black is the co-founder and CEO of SHOUT and UniTaskr, an entrepreneur building businesses at the intersection of the creator economy, technology and community.
His journey began as a safari ranger in South Africa before he co-founded UniTaskr to help students access paid work and bridge the gap between education and employment. Recognising the influence within that community, he went on to co-found SHOUT—turning everyday people into a scalable marketing channel for brands.
Today, Joseph leads SHOUT’s growth across the US and UK, combining a global network of more than 250,000 creators with technology and paid media amplification. The business has worked with brands including Adobe, Buffalo Wild Wings, HBO, Sky, Universal Music and Lionsgate, helping connect authentic creator content with measurable marketing outcomes.
Alongside its managed agency services, SHOUT is expanding through SHOUT Studio, a platform for brands and agencies to manage creator campaigns, and SHOUT+, which helps businesses identify and activate the social influence of their existing customers and employees.
Based in Los Angeles, Joseph brings a founder’s perspective on building communities, scaling a transatlantic business and helping brands move beyond one-off influencer partnerships toward ongoing creator programs that support awareness, advocacy and growth.
