20VC: Greylock's John Lilly on How Greylock Continues To Invest In The Next Big Markets, The Importance Of Building Tribes & Why There will Be Another Boom In Mobile

Venture capital investment strategies and the evolution of technology markets define the professional trajectory of John Lilly, a partner at Greylock Partners and former CEO of Mozilla. Building a robust professional "tribe" requires long-term, intentional investment in relationships rooted in shared ethical frameworks and mutual growth. While mobile technology currently faces a plateau in user adoption, future growth booms remain likely as society integrates advanced sensors and specialized mobile experiences. Furthermore, the productivity software landscape is undergoing a significant shift; legacy suites like Microsoft Office are losing their distribution advantage to purpose-built, collaborative tools like Quip and Figma. These modern platforms succeed by prioritizing design, real-time collaboration, and cloud-native functionality, signaling a broader transition in how users create and manage work in an increasingly mobile-first environment.
