WhatsApp is the most widely used messaging app in the world, built around encrypted one-to-one chats, group threads, and voice and video calls. Status updates, broadcast lists, and the Business app add light CRM on top of conversation. Widely used by VC firms outside the US to stay in founder chats, route warm intros, and handle fast diligence back-and-forth where email would feel slow and Slack would feel too formal.
