Simantic (YC F26) – Firmware Simulation for AI Agents

Hi HN, we're Ahnaf and Seungmin from Simantic (https://simantic.com). We are building the simulation layer that lets engineers and AI agents test and validate firmware without hardware.Before Simantic, we were ex-firmware engineers at companies like Neuralink and Tesla. We’ve worked on some of the coolest projects, like the Cybertruck and Roadster, back when they were still early prototypes.We started working on firmware back when ChatGPT didn’t exist yet, but over the years, we saw how much of the engineering and development work has been automated as the frontier models improved to this point. In software, AI can run and test code inside your computer in a matter of seconds. But as firmware engineers, we didn’t have that luxury. An AI agent can write firmware in seconds, but in order to test it, we had to flash a physical board, then manually run tests using expensive and clunky tools with software made over a decade ago.To speed up the validation loop, we built the simulation layer that lets AI agents test the firmware and make decisions based on evidence, instead of waiting for the engineer to run tests for them. We used to spend hours testing our firmware manually on devboards, but now we use our own simulation to validate firmware in seconds.What we offer: - Virtual devboards you can program and run with a single API call, without leaving your terminal. - An AI code reviewer for firmware, that makes informed decisions based on evidence, using our simulation as a verification engine. - A CI/CD pipeline for your hardware projects that validates your firmware against a simulated version of the microcontroller on every commit.Here is a demo of our simulation used in an AI code review session: https://www.youtube.com/watch?v=kBK1ZjGWWbQOur users are using Simantic for bare-metal and RTOS development for applications like flight controllers, electric vehicles, robotics, and satellites. For safety critical systems like avionics and
