OceanTech Acquisitions I Corp. functioned as a special purpose acquisition company, or SPAC, lacking any substantial business operations of its own. Established in New York in 2021, the entity's primary objective was to facilitate a business combination, which could involve a merger, stock exchange, or asset acquisition, with a suitable operating enterprise. Initially, its focus for potential targets centered on businesses operating within the leisure marine, yachting, and superyachting industries. After several efforts to identify and finalize a merger, including a planned combination with Regentis Biomaterials, the company ultimately announced its liquidation and subsequently delisted its shares from Nasdaq in 2024.
