The former CEO of a payment processing company had a taste for strip clubs and high-priced escorts — and was so enamored with one of the women he gave her and her mother jobs, a lawsuit charges.

The company, iPayment, alleges in the lawsuit that Carl Grimstad expensed frequent golf outings, visits to jiggle joints and shopping sprees for his wife — running up a tab of about $445,000. The expenses caused “financial and reputational harm,” the company charges in the suit filed in Manhattan Supreme Court.

Grimstad, 49, who was co-founder and president of iPayment before becoming CEO in 2011, invited employees to emulate his lavish ways — encouraging them to also put trips to strip clubs on expense accounts, court papers show.

In late 2007, Grimstad and another iPayment employee visited the Spearmint Rhino strip club in Las Vegas, where they “became acquainted with an employee of that establishment who also worked as a personal escort,” papers charge.

Grimstad offered the escort $4,000 for “certain sexual activities,” according to the suit.

The pair established a bond, and Grimstad hired the prostitute as an employee in 2008 “despite lacking any apparent qualifications for the job for which she was hired,” papers read.

Carl Grimstad allegedly treated himself to a $4,000 escort on the company dime.

“Shortly thereafter, the escort’s mother was also hired as an employee of iPayment,” the suit says.

The escort was fired in 2012 and given $37,000 severance, the suit claims.

Grimstad’s attorney Marc Kasowitz said the allegations regarding his client’s wild lifestyle were investigated and found to be false.

“Carl was not terminated for cause. This is more proof that this lawsuit contains total fabrications,” Kasowitz said.

Grimstad’s alleged excesses didn’t stop there. Among his other indulgences, according to the suit: $288,000 in expenses at the Mark Hotel on the Upper East Side, $10,000 in clothes for a bodyguard and chauffeur and $70,000 for his wife’s “extravagant lifestyle.”

Grimstad’s wife, Jessica Grimstad, is also named in the suit and described as a “bit player on the New York social scene, having been transplanted from Nashville to New York.”

Jessica Grimstad refused to speak with a reporter as she swept into the couple’s E. 63rd St. townhouse.

In September, Grimstad sued over his ouster from the tech firm, which provides payment processing for retail and e-commerce sellers.

The new lawsuit also alleges the company fell prey to a $12 million embezzlement scheme right under Grimstad’s nose between 2008 and 2012.

Grimstad, meanwhile, averaged close to 100 rounds of golf per year between 2013 and 2016, the papers claim.
