HIL platform automates tests to validate hardware behavior

A new hardware-in-the-loop (HIL) testing framework claims to make automated, hardware-validated testing accessible to every team by offering engineering resources previously available only at large enterprises. This new testing framework—called BootLoop Test—unifies bench, continuous integration (CI), and end-of-line validation on a single platform.

Though HIL testing is one of the most valuable practices in the hardware world, it’s mostly adopted without any rigorous testing infrastructure. That’s because building a hardened HIL framework requires dedicated test engineers, months of custom development, and specialized skills that most firmware teams don’t have.

Consequently, many companies either forgo testing entirely or rely on ad hoc scripts and manual validation processes. That, in turn, slows development cycles, misses errors, and causes fragile release processes.

BootLoop, a startup that provides an AI platform for firmware and embedded development, addresses this problem by offering a complete HIL platform that spans the entire embedded product lifecycle. As a result, a hardware company can go from zero testing infrastructure to a fully automated pipeline in days.

“Most hardware companies know they need more rigorous firmware testing,” said Noah Pacik-Nelson, CEO of BootLoop. “They just don’t have the time or the tools. We built BootLoop Test, so they don’t have to choose between shipping quickly and shipping robust code.”

BootLoop’s agent ingests PCB design files and component datasheets to automatically generate tests that validate real hardware behavior down to the register level. The agent connects to serial monitors, debuggers, and test equipment to iterate until the code runs clean. So, test teams can go from zero testing infrastructure to a full CI pipeline on real hardware in hours by using a single command install.

BootLoop—a Y Combinator company founded by SpaceX and MIT Media Lab engineers—covers the entire embedded development lifecycle, including development, testing, and debugging. The company was founded in 2025 and is based in San Francisco.
