Acquired by Microsoft December 2016 · $26.2B ($196.00 per share, all cash) · source ↗

LinkedIn is the professional network — profiles, connections, job listings and a feed built around work rather than friendship. Reid Hoffman started it in his living room in late 2002 with four co-founders drawn from PayPal and his earlier company SocialNet, and the site launched in May 2003. It went public on the NYSE in 2011 and Microsoft bought it in 2016 for $26.2 billion in cash, still among the largest software acquisitions ever made; it now runs as a Microsoft subsidiary with more than a billion registered members.
