About Jim Keller

Jim Keller is chief executive officer of Tenstorrent and a board member at AheadComputing. AheadComputing builds open-standard RISC-V CPU cores. Keller is named as the architect behind DEC Alpha, AMD K8/Zen, and Apple A4/A5.

AheadComputing announced on February 26, 2025 that Keller had joined its Board of Directors. He was also an early supporter and angel investor in the company. He took part in its $21.5 million seed round, which Eclipse led. AheadComputing's view is that he joined because he shares its belief that RISC-V is the next great architectural shift.
