Launch HN: Simantic (YC F26) – Firmware Simulation for AI Agents

By · Published by Everything Blog

In short

The company offers virtual development boards programmable through API calls alongside an AI code reviewer that uses simulation as an automated verification engine. These tools are tailored for both bare-metal and real-time operating system environments used in satellites and flight controllers. To ensure fidelity, the team runs continuous hardware validation rigs that keep software models matched to real-world components.

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…
