About the Founder
Joe Schellenberg, founder of SolarStamp.io (an ENGletter Company), began his career as an independent contractor supporting solar companies with residential installations. By 2018, he saw firsthand how inefficient the communication and tracking process was between solar companies, engineers, site surveyors, and designers. To solve this, Joe envisioned a simple web application where every step of a solar project could be managed in one place—with better accuracy, faster communication, and streamlined organization. This innovation dramatically reduced project timelines from survey data to engineer letters, improving management, timelines, and cash flow. Then in 2024, as the industry’s needs evolved, SolarStamp.io expanded its capabilities to include city permit services and solar panel removal & reinstallation (R&R) projects—further strengthening its role as an all-in-one solution for solar and roofing companies.
