Four-Person YC Startup Simantic Aims to Let AI Agents Simulate Firmware Hardware

Simantic, a four-person Y Combinator F26 startup founded in 2025, is building hardware simulation aimed at letting AI agents work on embedded firmware without physical prototypes. A job posting says the platform is based on SPICE and Xyce. The company is still hiring a Lead Simulation Researcher, and no simulation fidelity results have been published.
