Arche has expanded through strategic acquisitions, notably Laforêt in 2017, Guy Hoquet in 2019, Century 21 France in 2021, and Nestenn in 2022, which made it the French market leader and a European leader in real estate transactions. The group has faced controversy over management practices, with media reports in 2024 alleging burnout, harassment and abusive dismissals at subsidiary Citya.

Arche was founded in 1990 in Tours by Philippe Briand. Starting as a small agency, it grew over three decades into a major player in the French real estate sector. A significant expansion phase began in 2017 when Arche acquired the Laforêt franchise network for an estimated €30–40 million. In 2019, Nexity sold its majority stake in Guy Hoquet l'Immobilier to Arche, adding another well-known brand to its portfolio. The group's growth accelerated in May 2021 with the acquisition of Century 21 France from Nexity for approximately €80 million. In March 2022, Arche acquired the Nestenn network, becoming the number one real estate network in France and a European leader in real estate transactions, with a business volume of €1.6 billion and 23,500 direct and indirect employees. As of 2025, the group reports 2,870 subsidiaries and agencies, 186,000 transactions, and 24,600 employees. Arche is part of the Citya group holding and remains privately held, with Philippe Briand owning the quasi-total of the capital. The group has also faced controversy: in 2024, media investigations reported allegations of burnout, harassment and abusive dismissals at subsidiary Citya.
