# Rochan Sankar

> Rochan Sankar is the founder and CEO of Enfabrica, a Silicon Valley startup building networking silicon to move data between the GPUs, CPUs and memory that power large-scale AI. A 26-year semiconductor veteran who ran Broadcom's data center Ethernet switching business before striking out on his own in 2019, he bet the company on a single idea: that AI's real bottleneck is not compute but the plumbing that feeds it. In September 2025, Nvidia paid more than $900 million to license Enfabrica's technology and bring Sankar and much of his team in-house.
