Fungible, a Santa Clara-based company founded by Juniper Networks co-founder Pradeep Sindhu and ex-Apple senior vice president of software engineering Bertrand Serlet, has raised $200 million in Series C funding led by the Softbank Vision Fund, with participation from Norwest Venture Partners and other unspecified existing investors. With this funding, Fungible has now raised more than $300 million since inception. Other investors in the company include notable names like Battery Ventures and Mayfield Fund.

The company builds semiconductor technology that it calls “data-centric computing”. In acute terms, Fungible builds semiconductors that helps data centers keep up with increasing loads while maintaining existing hardware infrastructure. The company sells a programmable microprocessor named the “Fungible Data Processing Unit (DPU)” that it says improves execution of workloads in data centers. The company is aiming to get hold of a significant portion of the $120 billion+ data center infrastructure market.
