Formation 8 was a venture capital firm founded in 2011 by Joe Lonsdale, Brian Koo, and Jim Kim. The firm aimed to support entrepreneurs seeking to transform global industries through technological innovation. Formation 8 raised nearly $1 billion across two funds, investing in companies such as Oculus (acquired by Facebook), RelateIQ (acquired by Salesforce), Plated, Oscar Health, and Radius.

In 2015, the firm announced it would not raise a third fund and would focus on managing its existing portfolio, marking the end of its active investment operations.
