How Some Companies Survive, Even Thrive, in Viral Crisis Associated Press WASHINGTON - When the coronavirus struck the United States hard last month, 22-year-old entrepreneur David Zamarin knew his company needed a Plan B -- fast. As the economy essentially shut down, demand for his stain-resistant coatings was sure to drop. So Zamarin decided to retool his company, DetraPel, in Framingham, Massachusetts, to start making disinfectants to help fight the virus's spread. Within weeks, "we completely changed our whole system." Sales of the DetraPel ecoCleaner & Disinfectant have been strong, he said, and Zamarin expects to produce the cleaner even after the health crisis has passed. "I don't want this to be a one-time thing,'' he said. "I don't want to capitalize on this to make short-term money.'' .
