OverviewMore SignalsSourcesDependency mapStoryMilestones

A fusion energy startup pursuing a pulsed magnetic (inertial) fusion approach designed to support affordable commercial fusion power, backed by a $900 million Series A round led by General Catalyst with capital released as project milestones are achieved. Pacific Fusion's latest prototype delivered more than 440 gigawatts of peak output power and roughly 1.1 megavolts peak voltage in an ultra-fast 80-nanosecond pulse, at the scale required to drive fusion conditions.
