Who Is Lori Greiner’s Husband? All About Dan Greiner

Lori Greiner met her future husband and business partner, Dan Greiner, at a Chicago bar in the 1990s.

The businesswoman is best known for her role on ABC’s hit reality show Shark Tank, where she’s invested in companies like Scrub Daddy and the Squatty Potty. Before she became a TV icon, Lori got her start as an inventor around the time she met her now-husband Dan. The couple first met at a sports bar in Chicago, and they’ve since become business partners.

Since the beginning of her career, Dan has advocated for and supported Lori as she’s achieved success in business and become a household name. In fact, he even sketched her first invention.

Lori wrote a sweet dedication to her husband in her 2014 book, Invent it, Sell it, Bank it!: Make Your Million-Dollar Idea into a Reality. "You stood by me, loved me, and made me believe in myself. You have changed my life profoundly. I will love you forever," she wrote.

So who is Lori Greiner’s husband? Here’s everything to know about Dan Greiner and his relationship with the entrepreneur and reality star.

He met Lori in Chicago in the 1990s

Lori and Dan met in the 1990s when they were both living in Chicago.

In a 2009 article published in Crain’s Chicago Business, Lori revealed that they met at Kincade’s, a sports bar located in the city's Lincoln Park neighborhood. Shortly after, they began dating.

He invested in her first entrepreneurial pursuit

In the 1990s, Lori came up with her first big invention: a jewelry organizer. To help make it happen, Dan made a meticulous sketch of Lori's idea and the couple took out a large loan to manufacture the invention.

“He’s cautious – not at all the type to push the envelope,” Lori wrote in her book, per Country Living. “And yet, in this instance he was on board from the minute I told him about my idea.”

She continued, "Dan was supportive of my efforts from the very beginning. If I believed my product was a hero, so did he."

By the end of 1996, Lori was promoting her product with live demonstrations at JCPenney — and Dan was there to support her, according to a speech she gave at the Chase Women’s Business Symposium in May 2015.

He would pretend to be a stranger and say, “That looks pretty cool. I think I might buy one of those for my wife.” This would, in turn, attract more customers to Lori’s demonstrations at the retail store.

“We were a little Bonnie and Clyde-like,” she said about Dan’s marketing tactic.

He left his job to work at her company

Dan started his career at Grant Thornton LLP as a consulting, audit and tax specialist from 1987 to 1990. After that, he became a division controller at Bell & Howell from 1990 to 1998, per his LinkedIn.

Around the time her first invention gained success, in June 1996, Dan started working as the vice president at Lori’s company, For Your Ease Only, Inc. For over 20 years, Dan has been the "Owner, CFO, COO, Founder” of Lori Greiner Companies.

His bio on LinkedIn explains his collaboration with his wife: "Dan joined her to run the financial and operations sides of the new business. Together, Dan and Lori have patented over 100 innovative products."

They work closely together

As the co-founders of Lori Greiner Companies, Lori and Dan work in tandem. In fact, Lori even talked about their synergy in her book.

“Dan is a numbers guy; I’m the inventor,” she wrote. “That’s why we’re a perfect team.”

The Crain’s Chicago Business article even mentioned that the couple share a desk at their Chicago office.

He and Lori have patented more than 100 products

Per his LinkedIn page, Dan says that he and Lori have worked together to patent more than 100 “innovative products,” many of which have been featured on Lori’s QVC show Clever & Unique Creations.

In addition to her jewelry-arranging invention, Lori’s other key patents include a makeup holder and a swivel-style organizer.

They enjoy working together

Lori and Dan have collaborated on patenting products together for over 20 years. In a 2016 interview with Young Hollywood, she talked about her family and conducting business.

“When you’re an entrepreneur, it’s really a 24/7 thing,” Lori said. “There isn’t really work-life balance. You have to be committed and willing to work Sundays, Saturdays, evenings — it’s not where you can just say, ‘It’s 9 to 5, I’m leaving.’ "

“So I think the truth is that you should try to involve your family in your business. That’s what I think. Works for me," she concluded.
