SiFive, a startup specializing in RISC-V processor intellectual property, announced a $400 million funding round on Wednesday. The investment was led by Atreides Management, with participation from other investors including undisclosed parties. This brings SiFive's total funding to over $350 million since its founding in 2015.
The company plans to allocate the new capital toward enhancing its offerings for AI data centers. SiFive's technology enables customizable chip designs based on the open-source RISC-V architecture, which is gaining traction as an alternative to proprietary architectures like Arm and x86. This funding comes at a time when AI workloads are driving demand for efficient, scalable computing solutions.
SiFive was co-founded by the creators of the RISC-V instruction set architecture at the University of California, Berkeley.
The RISC-V standard, which is royalty-free and open, allows companies to design processors without licensing fees associated with closed architectures. SiFive provides IP cores, development tools, and custom silicon services to clients in sectors including automotive, consumer electronics, and data centers.
The startup has previously raised funds in multiple rounds, including a $145 million Series D in 2021.
Key customers include semiconductor firms and tech companies seeking to integrate RISC-V into their products. As AI applications expand, RISC-V's flexibility is positioned to support specialized accelerators and edge computing devices.
Atreides Management, a Boston-based investment firm focused on technology and innovation, led the round.
Other participants were not named in the announcement. The funding values SiFive at an undisclosed amount, though prior reports indicated a valuation exceeding $1 billion following earlier investments. This infusion of capital affects SiFive's employees, now numbering over 300, and its global operations with offices in the United States, China, and Europe.
