Christine Hunsicker, founder and former chief executive of CaaStle Inc, was sentenced Thursday to five years in federal prison and three years of supervised release after pleading guilty to securities fraud. CaaStle, a web‑based clothing rental service for plus‑sized women founded in 2019, had reached a valuation of more than $1.4 billion and later sold its platform to other fashion firms. Prosecutors said Hunsicker submitted falsified income statements, fake audited financial statements, fictitious bank records and other fabricated corporate documents to investors. She claimed the funds would be used to purchase discounted shares from existing shareholders, but authorities said she invented the existence of those shareholders. The scheme, which spanned from 2019 to 2025, allegedly defrauded hundreds of investors of $300 million. Even after law enforcement seized her electronic devices in March 2025, prosecutors allege she continued fraudulent activity. CaaStle filed for bankruptcy in spring 2025 after its financial condition was disclosed as heavily exaggerated. Hunsicker’s attorneys did not respond to a request for comment. The case underscores the risks of securities fraud in emerging fashion‑technology companies and marks one of the largest fraud prosecutions in recent years.
