Fusionality's shift from pure physics research to control systems and simulation tools reflects a maturing realization that fusion's bottleneck is no longer theoretical but operational—startups need software to iterate on reactor designs faster than hardware cycles allow. This follows the pattern of AI infrastructure plays (similar to how Hugging Face abstracted model training complexity). The next wave of fusion funding may flow to software-first companies rather than reactor designs alone, altering how the 30+ fusion startups competing for grid deployment allocate capital and talent.
