Sphere Semi

Sphere Semi is an AI-native semiconductor company developing custom analog chips using proprietary AI models and algorithms. The company's AI engine generates, evaluates, and optimizes circuit designs—producing thousands of layouts in days that beat human baselines and expand the design space. Sphere Semi focuses on RF components (LNAs, PAs, filters, phase shifters, beamformers, synthesizers) and mixed-signal IP (SerDes, ADCs, DACs) targeting wideband and mmWave/sub-THz applications. All designs are DRC/LVS-clean, PDK-aware, and manufacturable by construction, enabling faster convergence and better unit economics for customers who need custom chips or drop-in IP.
