"I worked with Closed Loop to review the PCB designs I need to take into mass production. After manufacturing a couple of prototype boards, we ran into several issues, and I wanted a second opinion on the current design. Although we had already identified several issues from the prototype boards and addressed those concerns, I wanted to make sure the design was solid before committing to mass production. Beyond confirming that the fixes for the known issues were sound, I also wanted to verify there were no other problems lurking. Closed Loop went over the design thoroughly and delivered a report that pointed out the weaknesses in the current design, backed by simulations they conducted. With that report in hand, I now understand the limits of the current design and can make better-informed decisions going forward"

"We were under schedule pressure to get a radar board out to manufacturing, and there were parts of the design I wasn't comfortable with. On the first call, Closed Loop was asking questions our own team hadn't raised. We brought them in for a full review and they found several problems that would have been expensive to fix after the boards were built. The engagement itself was well run. We always knew where things stood and never had to chase anyone for updates. The board went out on time and I was confident in it, which was not where we started. I'd hire them again without hesitation"
