Recent highlights

Paxos Medical’s main disclosed financial milestone is a $2.073 million Seed round announced on May 8, 2026, its only listed funding round. The company is developing UnderControl™, an implantable neuromodulation therapy for underactive bladder (UAB), intended to help patients initiate voluntary urination rather than simply suppress bladder activity. The stated approach is designed to activate the voiding neural circuit through a targeted, patient-controlled signal, with outpatient placement described as a design goal. Leadership expanded in April 2026, when Jon Ruais was listed as COO, Co-Founder, and Board Member; Jeff Erb is CEO, Co-Founder, and Chairman, and Matthew Fraser is CSO and Co-Founder. The product concept draws on more than 40 years of research at Duke and the University of Pittsburgh, as described in the company’s product positioning. No specific product launch, partnership announcement, award, or additional financing milestone is included here, so the available picture centers on the Seed financing, leadership, and development of UnderControl™.
