Nauticus Robotics, a developer of robots, software, and associated services, went public via a SPAC merger with CleanTech Acquisition, a publicly traded special purpose acquisition company, in a $561m deal. “We are pleased with this outcome that takes Nauticus public and allows them to further their mission of positively impacting the cost and emission profiles of the massive ocean economy. I continue to believe Nauticus’ Robotics-as-a-Service business model will be appealing to public markets investors and have confidence in their long-term growth trajectory," Eli Spiro, CLAQ CEO.
