A family business

Founded in 1911 by the great-great-uncle of the current CEO Stéphane Decayeux, this Picardy company is essential in subcontracting (STI for industrial subcontracting) in metal processing. Today, she goes further by launching her brand of luxury products.

It was in 1985, after studying engineering in Lille, that the current CEO Stéphane Decayeux joined the company.

He is then in charge of the computerization of the company. “a great way to get to know all aspects of it”.

In 1993, he took over from his father at the head of the company, which had become a holding company three years earlier.

The whole is impressive with nine production sites, six in France (half of which in Picardy) as well as in Morocco and Romania. “Each site specializes in an activity”, specifies Stéphane Decayeux.

3000 tons of raw materials

10 million parts delivered to customers

Each year, 3,000 tons of raw materials are processed there, with 10 million parts delivered to customers. The company has 300 jobs in France and has a turnover of 50 million euros.

“We have been progressing since 2008, but in the meantime we have turned the page on the automotive sector, a sector in which we previously worked”. confides the CEO of Decayeux STI.

A new challenge

A new ambition

The company has recently taken up a new challenge, the launch of its own brand of luxury products for golfers: Decayeux Golf. “We wanted to offer luxury products, which we know how to do, and get out of the constraint by our customers by being autonomous”.

After a long period of reflection and study of 18 months, the project is set up. “We launched the site in the summer of 2013 and are in discussion to have a prestigious ambassador”. A graduate of a business school, Stéphane Decayeux’s son, Benjamin, was awarded the project.

Stéphane Decayeux has been a member of the Entreprendre en Picardie network since 2014, where he shares his long experience as a business leader
