A Manhattan marketing executive was sentenced Monday to serve between three and nine years in prison after admitting to embezzling nearly $6 million from his former employers over an eight-year period. Michael Collins, 62, pleaded guilty in April to charges related to the theft, which prosecutors say funded a lavish lifestyle that included the purchase of a $150,000 engagement ring.

Collins, who served as the chief marketing officer for the digital banking platform nCino, used the stolen funds to finance a range of luxury expenses such as executive club memberships, high-end designer goods, fine dining, and extensive travel and lodging, according to the Manhattan District Attorney’s office.

Prosecutors detailed how Collins orchestrated the scheme by establishing two fictitious companies through which he funneled payments from his employers. The fraudulent activities spanned from March 2016 to April 2024. At Monday’s sentencing in Manhattan Supreme Court, Collins appeared wearing a white T-shirt beneath a gray zipped hoodie.

Manhattan District Attorney Alvin Bragg emphasized the importance of the sentence, stating it serves as a warning to executives engaging in similar misconduct. “I hope this sentencing sends a message to New York executives who exploit Manhattan businesses — you will be held accountable,” Bragg said.

The plea deal, arranged by the DA’s office, stipulated Collins’ prison term within the three- to nine-year range. The case highlights ongoing concerns about corporate fraud and financial crimes targeting businesses in New York City.
