Leadership Comments

“To lead the frontier of AI after a lack of investment in the electrical grid for decades requires a complete rethinking of energy deployments. Gigawatt-scale deployments in tight time windows necessitate owning the full stack end-to-end," said Pat Becker, co-founder of TAR.

"We are excited by the demand from our customers. Our focus now is scaling supply to make a real impact on the power shortage stopping the scaling of compute," said Lenny Soenke, co-founder of TAR.
