Horizon Space Acquisition I Corp

A "blank check" company — formally a special purpose acquisition company, or SPAC — formed in the Cayman Islands in 2022 to raise money and eventually merge with a private business so it can go public without a traditional IPO. Despite the space-themed name, it makes no products of its own; its job is to find a company to combine with. The "Horizon" name hints at far-off ambitions, though the target it ultimately paired with was SL Bio, a Taiwan biomedical firm developing cellular therapies for hard-to-treat cancers.
