WhatsApp's final financing round value was $1.5 billion before buyout

WhatsApp was reportedly valued at 1.5 billion dollars in the final round in July 2013, resulting in its acquisition by Facebook.

With Sequoia being the sole investor, the company apparently had three rounds of financing.

According to documents unearthed by VC Experts, WhatsApp went from a 250k dollars seed round in 2009 to an 8 million dollars round at an 80 million dollars valuation in 2011, Tech Crunch reported.

The final round that was deemed as Series C, but was technically a Series B was a 52 million dollar round back in July 2013.
