“Our investors are energized by MicroTransponder’s vision to enable treatment for the millions of stroke survivors that have ongoing moderate to severe upper limb impairment. Our goal has always been to establish Vivistim Paired VNS as the gold-standard stroke rehabilitation intervention. Today is the day this therapy can help more stroke survivors get back to the daily activities, hobbies and experiences they love,” CEO and director Richard Foust said in a statement.

The seed and Series A rounds were led by JAZZ Venture Partners, Root Ventures, Mithril Capital, Global Asset Capital and Free Solo Ventures. The debt facility came from Silicon Valley Bank. The fertility startup’s first product is aimed at identifying the healthiest sperm to improve IVF outcomes. 

“Oma Fertility is capitalizing on the opportunity to bring leading-edge technological advancements to the fertility space, meeting the demands of rising infertility rates,” cofounder and CEO Gurjeet Singh said in a statement. “Our mission is to improve outcomes for more families facing fertility issues and we strive to create a place where everyone seeking to have a child has access to the most advanced, successful fertility treatments.”
