Mayfield is an early-stage technology investor focused on being the first institutional backer of AI founders, with most of its investments beginning at company inception.

Its AI investing reaches into the physical infrastructure needed for adoption as well as software. The firm’s Lumilens investment addresses optical connectivity between processors and computing systems, illustrating its interest in technical bottlenecks below the application layer.

Mayfield’s CXO of the Future community connects it with enterprise leaders. That commercial perspective complements its inception-stage work when founders need to understand the requirements of corporate buyers for a new technology.
