WhatsApp

Global leader in consumer messaging with the largest user base of any messaging app, increasingly positioned as a business communication and commerce channel within Meta's ecosystem

WhatsApp is a cross-platform messaging application owned by Meta Platforms, originally founded in 2009 and acquired by Facebook (now Meta) in 2014 for approximately $19 billion. With over 2 billion active users worldwide, it is one of the most widely used communication platforms globally, particularly dominant in markets across Latin America, Europe, India, and Africa. The platform offers end-to-end encrypted messaging, voice and video calls, and file sharing for consumers, while providing businesses with dedicated tools through WhatsApp Business and the WhatsApp Business API. In the AdTech and marketing ecosystem, WhatsApp serves as a direct-to-consumer engagement channel rather than a traditional advertising platform. Businesses can use the WhatsApp Business App for small-scale customer interactions, while larger enterprises leverage the WhatsApp Business Platform (API) to send transactional messages, notifications, and promotional content at scale through approved Business Solution Providers (BSPs). Meta has been gradually expanding monetization through click-to-WhatsApp ads on Facebook and Instagram, as well as in-chat commerce features. WhatsApp's significance in AdTech continues to grow as brands seek conversational marketing and customer service automation capabilities. The platform supports chatbots, automated messaging flows, product catalogs, and payment integrations in select markets. As third-party cookies decline and privacy regulations tighten, WhatsApp's first-party, consent-based communication model positions it as an increasingly strategic channel for performance marketers and CRM-focused advertisers.
