I only have ASX broker data. Since 20th Sept NASDAQ volumes have been very low so if anyone accumulated and held out of that 1.7m traded then they would be holding at a decent loss - similar to the ones shown above.
Worth reviewing the SEC filings for Sezzle director Paul Purcell too - he held 261,565 shares in mid May 2023 and acquired almost 125,000 shares on market since that date (ASX and recently NASDAQ) bringing his total to 384,573. His average buy would be in the $20s too (aud).
