He has invested personally in roughly a half dozen unicorns and decacorns with a combined market capitalization of over $150B, including three IPOs (Okta, Toast, and Desktop Metal), and is known for deliberately investing at the frontier in ideas that may sound nuts at first, often before a clear market exists.
