Marvell Technology designs chips for the infrastructure that moves and stores data: networking silicon, storage controllers, and the electro-optics that link servers inside data centers. Its fastest-growing business builds custom AI accelerators for hyperscale cloud companies that want alternatives to off-the-shelf GPUs, deals measured in billions once a design wins. Telecom carriers and enterprise networking round out the customer base. Founded in 1995, Marvell is fabless, concentrating on design while foundries manufacture.
