An Irish deep-tech startup building open-source RISC-V networking silicon for the AI era.
PacketFive exists to break the proprietary lock-in that constrains modern AI/HPC networking. We build open-source, hardware-accelerated network silicon using the RISC-V ISA, enabling organisations to deploy programmable, trusted, and efficient networking without vendor dependency.
Our flagship product, KESTREL-V, brings eBPF hardware VMs and Trusted Execution Environments to RISC-V silicon — making programmable networking safe, fast, and verifiable.
Core technology is open-source first. We believe open standards and open hardware accelerate the entire industry.
Our engineering culture is rooted in academic rigour. We publish our work, engage with the research community, and build on proven science.
We contribute to upstream RISC-V, eBPF, and Linux communities, and co-design with HPC practitioners and AI infrastructure teams.
