PicoJool announced that it raised $27.5 million in Series A funding led by Socratic Partners, with participation from Hudson River Trading (HRT). The HPCwire announcement presents this as funding raised, rather than a fundraising target or an undrawn financing facility.

The round follows a $12 million seed financing led by Playground Global. The announcement explicitly places cumulative funding at $39.5 million.

PicoJool’s disclosed business focus is optical connectivity for AI infrastructure, and the announcement frames the financing around scaling that technology.
