Rimal Semiconductors

What Rimal Semiconductors does

Rimal Semiconductors is a fabless semiconductor design company headquartered in Riyadh, Saudi Arabia, specialising in high-performance power chips for energy, mobility, and industrial applications. Founded in 2025 as Saudi Arabia's first fabless power semiconductor company, Rimal designs chips in-house across five technology platforms — Versatile MOSFETs (30V–250V), Efficient SJ MOSFETs (600V–800V), Robust IGBTs (650V–3300V with development extending to 6500V), High-Performance SiC (650V–1200V, developing 1700V), and Compact GaN (100V–650V) — while outsourcing wafer fabrication to international foundries in Taiwan, Korea, and China, with active discussions to onboard US-based foundries for supply chain diversification.

The company operates three service lines: custom Chip Design with a stated 3-month turnaround from concept to mass production, end-to-end PCBA Development and ODM services with a 5.5-week-or-more delivery timeline, and a Design Training Program that trains Saudi engineers in chip design, verification, and testing through real projects and international expert exchange. Its target customers are enterprise buyers across energy (solar inverters, grid infrastructure, storage), mobility (EVs, fast charging, automotive electronics), and industrial (motor drives, automation, oil and gas) verticals, with secondary exposure to defence/aerospace and consumer electronics. The publicly identified pipeline includes six contracts, one of which is with a major Egyptian corporation spanning defence systems, power grid infrastructure, and data centre technologies, and a regional distribution agreement covering Turkey, Egypt, Morocco, Tunisia, and the UAE is being finalised.

The business model is project-based with quote-based pricing for both chip and PCBA engagements, generating revenue through design fees and chip delivery contracts rather than standardised product pricing. The GTM motion is sales-led and enterprise-focused, with CEO Houssam Salem engaging directly on strategic accounts alongside a co-founder team that includes a CCO, CTO, and COO. Rimal is privately held, has 1-10 employees, and has received undisclosed strategic investment from Kahilan Asset Management's Deep Tech Fund plus bridge funding from Keheilan Asset Management and an undisclosed regional investor in March 2026. The company positions itself as a national champion aligned with Saudi Vision 2030, with a stated ambition to make Saudi Arabia the semiconductor gateway to MENA and enable local assembly by 2030.
