From Janitor to Billionaire: WhatsApp Founder Jan Koum's Inspiring Journey
•Jan Koum, WhatsApp founder, rose from poverty after immigrating from Ukraine with his mother, who battled cancer.
•He worked as a janitor and relied on food stamps; the building where he collected food stamps later became WhatsApp's office.
•Koum taught himself computer programming, dropped out of college for a Yahoo job, and later co-founded WhatsApp with Brian Acton.
•Driven by his experience with expensive calls, he built WhatsApp to connect people globally without cost, ads, or data tracking.
•Despite initial failure and financial struggles, Koum and Acton maintained their principles, eventually selling to Facebook but leaving when values clashed.
