Full Analysis
Rain AI aimed to build brain-inspired neuromorphic processors for AI workloads, promising massive efficiency gains over traditional GPUs. Sam Altman personally invested. But semiconductor development requires billions in capital — $60M wasn't close to enough for tape-outs and fabrication. The company ran into national security scrutiny (Saudi investment concerns) and shut down in 2025 without producing commercial chips.
