Envoy Medical, Inc., trading under the ticker COCH on Nasdaq, is a medical-device company focused on fully implantable hearing technology, best known for its Esteem device. The company reached the public markets through a merger with Anzu Special Acquisition Corp I, a blank-check vehicle sponsored by Anzu Partners that completed its IPO in 2021 and operated within the healthcare and medical-device sector. The de-SPAC transaction closed in late 2022, transitioning Envoy Medical into a publicly reporting company. The April 2023 Form 10-K filing with the SEC marked the company's first full annual report under its current public structure.
