iStock; Skye Gould/Insider The SPAC boom has infused billions into upstart companies such as BurgerFi and Tattooed Chef. But many are finding challenges on the public market, from short-sellers to annual reports. Many brands may not survive or may opt to sell themselves to a bigger player. Last month, Sarah Galletti fielded a question about marketing spending from an analyst — a common ask on earnings calls of publicly traded companies, but one that had an unusual answer. "We've had no marketing until January of 2021," Galletti said, adding that her company, the plant-based food brand Tattooed Chef, was still "gathering data" to determine its advertising strategy. The March call was Tattooed Chef's second as a public company.
