Addon

Founded in 2013 by Adrienne McCarthy, Addon Digital started as a specialist social media agency in Cape Town and has since grown into a wider digital offering. Retail names like Boxer Superstores, The International Colours Group and The Amrod Group sit alongside international clients such as The Rainforest Alliance, YBY and Manacor Holdings, giving the agency a client base that spans South African retail and global brand work.

Campaigns are built by a combined team of a Strategist, Copywriter, Graphic Designer and Videographer, covering social strategy, organic social management and content production. Google Ads/PPC work generates instant, keyword-based leads, while technical and content SEO target unpaid traffic through search. Website design packages come standard with responsive builds, email marketing integration, social media integration, SEO setup and analytics configuration, so a new site launches already wired into the other channels Addon runs. The service list also covers electronic newsletters designed to render properly across inboxes and devices, plus Bulk SMS and USSD campaigns for mobile-based communication.

Addon works without locking clients into fixed contracts, yet the agency's average retainer runs longer than five years. That contract-free retention pattern points to how retail and international accounts have stayed with the same strategist-copywriter-designer-videographer setup over repeated campaigns, rather than moving between one-off projects. From its base at The Old Foundry in Green Point, the agency has kept its social media roots central while layering in SEO, PPC, web design, newsletters and mobile messaging as additional services under one team.
