What Aion Silicon does
Aion Silicon (formerly Sondrel) is a UK-headquartered semiconductor design services firm founded in 2002 that delivers end-to-end custom ASIC and System-on-Chip (SoC) development for customers ranging from startups to hyperscalers. The company operates as a foundry-neutral and IP-agnostic design partner, providing architecture and IP selection, RTL design, verification, physical implementation, design-for-test, and volume production support across advanced process nodes from TSMC, Samsung, GlobalFoundries, and Intel. Its engineering teams are distributed across the UK (Reading HQ, London, Bristol), Spain (Barcelona), Morocco (Rabat), India (Hyderabad), and the United States (Santa Clara), with proprietary methodologies including the Helium & Neon flow (Queen's Award winner in 2009), the Scalable Architecture Framework, a ten-step SoC modeling process, and a FlexNoC-based ADAS design methodology that compresses advanced SoC design cycles from 4-5 months to 1-2 months.
The company's revenue model is project-based professional services, with engagements typically spanning multi-year, multi-stage programs from architecture through tapeout and production ramp; pricing is not publicly disclosed and engagements are quote-based. Customers are served across four primary verticals — AI accelerators, high-performance computing, automotive ADAS, and 5G/networking/communications — with the go-to-market executed via high-touch, consultative direct sales targeting both emerging semiconductor startups and large technology enterprises. Recent strategic moves include a $12 million RISC-V accelerator design win (May 2025), membership in the Intel Foundry Accelerator Design Services Alliance and Value Chain Alliance, the Barcelona Design Center expansion (November 2025), the appointment of Allen Sansano as VP Engineering (March 2026), and formal partnerships with Arteris (NoC IP) and Andes Technology (RISC-V).
Aion Silicon operates as a private company following its 2024 delisting from the London Stock Exchange's AIM market and its 2025 rebrand from Sondrel, having completed a planned leadership transition from founder Graham Curren to CEO Oliver Jones. The firm holds ISO 9001:2015 and ISO/IEC 27001:2022 certifications, is an ARM Approved Design Partner since 2016, and reports a track record of hundreds of successful tapeouts including its largest chip to date at 30 billion transistors (2020).
