ZeroRISC Raises $10M to Expand Open Silicon Security Stack

ZeroRISC has secured $10 million in seed funding to expand its open-source silicon security platform and bring its Integrity Management Platform (IMP) to a broader range of silicon supply chain partners, according to SiliconANGLE. The startup, founded in 2023 by OpenTitan creator Dominic Rizzo, is focused on delivering end-to-end security that starts at the chip level.

At the core of ZeroRISC’s approach is a commercial-grade chip built on the OpenTitan root of trust, which provides verifiable device boot integrity. Designed to operate independently of manufacturers or physical custody, the chip is part of a full-stack solution that addresses growing demands for stronger hardware security in supply chains and regulated environments.

ZeroRISC’s IMP combines secure silicon, embedded software, and cloud-based tooling to track and manage device integrity from manufacturing through in-field operation. The system enforces isolation and ownership rules at the firmware layer, below the OS, enabling flexible policy enforcement and secure lifecycle management at scale.

The company has also added post-quantum cryptography to its platform, implementing SPHINCS+ for firmware signing. The new funding, led by Fontinalis Partners and joined by investors including Analog Devices co-founder Ray Stata, will support the next phase of commercial growth and product development.
