From the article:
>"The company’s unaudited financial statements were reviewed by an auditing firm in May 2020. According to the complaint, the review concluded that Headspin’s cumulative revenues from inception through the first half of 2020 totaled only approximately $26.3 million, instead of the $95.3 million originally reported by the company. The review also calculated the cumulative net loss from Headspin’s inception through the first half of 2020, totaling approximately $15.9 million, instead of the $3.7 million net income originally reported by the company."
The first audit found the fraud (which probably means it just wasn't well covered-up).
