Chamath Palihapitiya:

Part of what makes it fun to work at Social Capital is the amount of time we take to think through the broad continuum of technology. The impacts of technology don’t stop after a Series A or a Growth round. Disruption, impact and getting to scale happen at all parts of the technological lifecycle — spanning a company’s existence as both private and public entities.
 In thinking through the broad impacts of technology, we increasingly find ourselves investing in public markets as well. I don’t view these as distinct efforts — I view them as a broad reflection of our world view on change, opportunity and leadership. In fact, many of our private companies drive a better understanding of many public companies (and vice versa).
