Marvell Technology
Marvell Technology is a Santa Clara-based fabless semiconductor company that designs the chips underpinning modern data infrastructure. Founded in 1995, it has pivoted under CEO Matt Murphy from consumer and mobile silicon into custom AI accelerators (XPUs), electro-optics, high-speed Ethernet switching, DSPs and storage controllers. Its parts move data inside and between the hyperscale data centers run by companies like Amazon, Microsoft and Alphabet, making it one of the key merchant and custom silicon suppliers powering the AI buildout.
Zettascale Computing Corporation
Zettascale Computing Corporation (formerly Exa Laboratories) builds polymorphic XPU chips that reconfigure their own dataflow architecture to match each AI model - delivering up to 27.6x greater energy efficiency than NVIDIA H100 GPUs. Founded by a 21-year-old Swedish dropout and a Cambridge-trained engineer, this YC S24 company is shipping prototype Grasshopper cards fully manufactured in America, with commercial release planned for 2026. Their ambition: make zettascale computing sustainable and become the hardware substrate for all future AI.
