If you’ve been watching Selling Sunset, you’re probably curious about Christine Quinn‘s husband, Christian Richard. The supposed tech wiz was introduced on the series during season 2 and the pair got engaged after mere weeks of dating. Though the rest of the cast was quick to bring the 41-year-old into the fold, we still have questions. Namely, what does the mysterious man do for a living — and how did it make him so rich? Here’s what we know.

“Christian is big in the tech world,” Christine revealed during the season 2 premiere of the popular Netflix series. “He went to MIT, and he’s a software engineer and has worked for multiple companies, multiple development projects.”

The real estate agent also told Women’s Health he was part of the creation of “the first online food delivery business.” Plus, the guy is so rich, he’s already retired (three years ago!) at such a young age.

Speaking of his finances, money seems to be almost no object for the businessman. He purchased his wife —whom he married in December 2019 — her Hollywood Hills dream home for a whopping $5 million. Plus, he built a state-of-the-art gym for her in their new home.

TheCinemaholic estimates Christian’s net worth to be close to $20 million, but it is unclear exactly where his bank account stands. One thing is for sure, though: The retired techie isn’t into flaunting his wealth very much.

“He’s never really cared about the finer things in life or fancy things at all,” Christine told Women’s Health about her hubby’s preferences. “So he just loves when I do my thing, and he trusts me and knows that I have really great taste. So, he’s always like, ‘You do your thing, I trust you. Whatever you pull together, it’s always fabulous.'”

Christine and Christian were set up by a mutual friend and the connection was instant. They got engaged weeks after they started dating, which was revealed on the season 2 premiere of Selling Sunset. The couple wed in December 2019 and footage from their nuptials aired on the season 3 finale episode.

It seems the mystery surrounding reality couple — and Christian’s job — is one of the reasons folks will keep watching!
