Alexandre Arnault, the son of Europe's richest man, is coming on board as an executive at Tiffany & Co. after four years as CEO of high-end luggage brand Rimowa, Arnault and Rimowa announced on Friday.

At Tiffany & Co., 28-year-old Arnault will be the executive vice president of product and communications, according to a press release. Tiffany & Co. is the newest acquisition of LVMH, the world's largest luxury goods maker, which is run by Arnault's father, billionaire Bernard Arnault. After a monthslong dispute, LVMH closed its deal to buy the iconic jewelry brand for $15.8 billion in October 2020.

Arnault announced his career move on Friday on Instagram, a platform he frequently uses to highlight new Rimowa products as well as personal news like that of his recent engagement to Geraldine Guyot, founder of French accessories brand D'Estrëe.

"I am now leaving the reigns of Rimowa to join Tiffany & Co in New York," Arnault wrote in the post. "I am honoured to have been part of the Rimowa family."

The post included a photo carousel of "a few snapshots of our incredible ride together," as Arnault put it, including Rimowa's collaborations with artist Alex Israel and streetwear brand Supreme.

"No matter the distance, Rimowa will always be in my heart," Arnault wrote.

Bringing change to Rimowa

Arnault, who leaves Rimowa after four years as CEO, will stay on as the non-executive chairman of Rimowa, according to a company press release. In 2016, Arnault convinced his father to acquire Rimowa and spearheaded a modern reimagining of the 122-year-old German luggage brand, collaborating with trendy brands like Supreme and Virgil Abloh's Off-White. Last year under Arnault's leadership, Rimowa launched a bevy of new products including backpacks and sunglasses.

As Arnault told Business Insider in a phone call in November, "Even before the pandemic, we thought that our products needed to be more part of people's everyday lives rather than just being at the airport or in the hotel room at the destination."

LVMH has been led by his father, Bernard Arnault, since 1989. Bernard is the richest man in Europe by far and the fourth-richest person in the world, with an estimated $117 billion net worth, according to Bloomberg's Billionaires Index. In the early months of the pandemic, Bernard saw more than $30 billion wiped out from his net worth as retail stores were forced to close and LVMH's share price plummeted. But his empire has since rebounded, leaving his net worth $8 billion higher than it was before the pandemic.

The luxury goods empire is a family operation. In addition to Alexandre, three other Arnault children hold leadership roles at LVMH brands. Delphine Arnault, 45, is Louis Vuitton's executive vice president. Antoine Arnault, 43, is the CEO of Berluti as well as LVMH's head of image, communications, and the environment. Both Delphine and Antoine sit on LVMH's board of directors. And 26-year-old Frederic Arnault is the CEO of Tag Heuer. (Bernard's youngest son, Jean, is still in school, according to Bloomberg.)

Rimowa's new CEO will be Hugues Bonnet-Masimbert, Rimowa's former executive vice president of sales and client operations, who also spent 10 years at Louis Vuitton.

"At my side for the past three years, Hugues has been one of the primary artisans behind this success, and I am delighted to see him promoted to this new role," Arnault said in a press release.

Another Louis Vuitton veteran, Anthony Ledru, will take over as Tiffany's CEO, replacing Alessandro Bogliolo.

Arnault's first day at Tiffany & Co. in his new home city of New York City was Friday, according to his Instagram, where he followed his big announcement with a photo of his Tiffany employee badge.
