- SiFive specializes in designing RISC-V architecture chips, positioning itself as a leading alternative to x86 and ARM architectures in the semiconductor market, particularly for AI applications.
- In April 2026, SiFive raised $400 million in an oversubscribed Series G funding round, bringing its valuation to $3.65 billion, with backing from prominent investors including Nvidia and Atreides Management.
- Key customers include major tech firms like Alphabet (Google), leveraging SiFive's customizable processor designs for their internal chip development, and partnerships with Nvidia to integrate RISC-V with NVLink technology.
- SiFive's ideal buyers are hyperscale data center operators seeking customizable, open-standard CPU solutions to differentiate their compute offerings, addressing the growing demand for flexible and efficient AI processing capabilities.
Engineering is SiFive’s largest department with 147 employees, accounting for just over three-fifths of total headcount. Business Management (18), Sales & Support (16), Finance & Administration (15), and Information Technology (14) form a balanced middle tier that supports product delivery and go-to-market needs. Smaller groups include Marketing & Product (10), Human Resources (6), Program & Project Management (1), and a miscellaneous “Other” category (6). The distribution underscores the company’s technology-centric structure, with operational, commercial, and people functions scaled to match its core design efforts.
SiFive’s workforce is distributed across ten primary hubs. Approximately 39 % of employees work remotely or in unspecified locations, while the largest named office is San Francisco with 72 employees. Bengaluru hosts 27 team members, followed by Austin (18), Portland (8), and Hsinchu (6). Smaller contingents sit in New York, Boston, Pune, and San Diego. This spread illustrates a hybrid footprint that combines a Bay Area headquarters with engineering centres in India, Taiwan, and key U.S. tech corridors.
