NxLite, the manufacturer of air-stable, energy-efficient coatings for glass and polymeric substrates, announced the final close of its Series A financing, a $3.5 million debt facility from RSF Social Finance, and the appointment of technology supply chain leader Erin Sawyer to its board of directors.
The first close of the round was announced in October 2025 at $9.2 million. The final close brings the Series A to $13.1 million, oversubscribing the company’s original $10 million target, with capital arriving over a 120-day second-close window from new and existing investors. The round was led by Crabtree Lane Alt, LLC, with new investment from VoLo Earth Ventures and continued participation from Earth Foundry, MUUS, New Climate Ventures, ACT Venture Partners, and strategic investors in the door, window, and building industries. Alongside the equity round, NxLite secured the $3.5 million debt facility from RSF Social Finance to provide additional non-dilutive capital supporting manufacturing scale-up.
Since the first close, NxLite has been adding capacity and enhancing its full-scale manufacturing capability at its Advanced Innovation & Manufacturing Center in Canton, Michigan, while adding partnerships with major players across multiple use cases. Erin Sawyer, the company’s newest board member, is a Venture Partner at VoLo Earth Ventures who previously served as Vice President of Supply Chain at Wrightspeed and Group Manager of Core Technologies at Tesla, where she executed global sourcing strategies and drove cost reductions across the Model S and Model X platforms during their global scale-up.
