A referral marketing tool for political campaigns that works atop Whatsapp

"In December 2021, the Hernández campaign signed a contract with Wappid, a software that on the surface resembles a social network, connecting supporters primarily via WhatsApp, which is used by roughly 92% of Colombians. But Wappid also uses referral marketing techniques and gamification to encourage registered users to grow their own personal support networks under the umbrella of Rodolfistas.wappid.com. The site was built and is operated using Wappid and is Hernández’s campaign team’s principal nexus of more than 500,000 supporters. Hernández supporters who spoke to Rest of World, like lead Hernández volunteer Andrés Cabrera, credit a substantial part of Hernández’s election success to Wappid’s network multiplier effect, which he called “the backbone of the campaign.”"
