WhatsApp

WhatsApp, a technology company headquartered in Menlo Park, California, was founded in the late two-thousands. It operates a widely used messaging application that facilitates communication across various devices. The company's core offering allows users to send text messages, make voice and video calls, and share media such as photos and videos, all without direct per-message or per-minute charges.

Initially, WhatsApp generated revenue through a small annual subscription fee, but later shifted to a model focused on business solutions. This involves offering tools and services that enable businesses to interact with customers directly on the platform, ranging from customer support to marketing communications. The wealth of individuals like Jan Koum and Brian Acton is tied to WhatsApp's success and its subsequent acquisition, reflecting the substantial value created by its global communication platform.
