Phast develops sustainable, high-performance polyhydroxyalkanoate (PHA) biopolymers intended for medical applications. The company plans to expand R&D, grow its team, advance product development, and accelerate commercialisation of its next-generation PHA-based medical products. To support those efforts, Phast secured a £1 million pre-seed funding package combining £500,000 in equity from an angel round led by Sheffield Angels with participation from Cambridge Angels and Mandashi, matched by a £500,000 Innovate UK Investor Partnership Grant. The funding increases the company’s runway for development and early commercial activities. Phast is headquartered in Sheffield.
