WhatsApp raised $58.2 million in its private phase starting with a $250K seed (Oct 2009), an $8M Series A (Apr 8, 2011) and a $50M Series C (Jun 30, 2013) that valued the company near $1.5B. Founded in 2009, WhatsApp built a simple, secure messaging app centered on end-to-end encryption and cross-platform reliability. Those early financings funded global user growth, encryption improvements and scaling infrastructure culminating in a high-profile acquisition that recognized WhatsApp’s massive global reach and product simplicity.
