when did whatsapp start

WhatsApp started in early 2009, with the company incorporated on 4 February 2009 and the first public iPhone version (WhatsApp 2.0) launching in August 2009.

Quick Scoop

• The idea and company: WhatsApp Inc. was created by Jan Koum in California on 4 February 2009, soon joined by Brian Acton as co‑founder later that year.

• The first app users saw: WhatsApp 2.0, the first widely used release on the App Store for iPhone, came out in August 2009 and is generally treated as the moment WhatsApp “really started” for the public.

• Expansion after the start: Support for Android followed in 2010, which helped turn WhatsApp from a small iPhone utility into a fast‑growing global messaging app.
