JSJ Corporation functions as an investment and holding company that manages a portfolio of manufacturing-focused businesses. It is based in Grand Haven, Michigan, and its holdings include GHSP, which is described as its largest portfolio company. A notable 2025 development involved the sale of assets to PrecisionX Group, with Hudson Technologies—the portfolio firm that manufactures precision metal components—being acquired by that buyer. Through its portfolio, JSJ supports manufacturing firms by coordinating management across its holdings. Positioned in the executive offices segment, the company acts as a parent organization rather than a producer of goods. The organization employs a few hundred people.
