Charterhouse announces partnership with ESTYA

March 12, 2025

Charterhouse Capital Partners, one of the longest-established private equity firms operating in Europe, announces that it has agreed to acquire ESTYA, formerly ERIS. Charterhouse will invest in partnership with ESTYA’s management, who are reinvesting in the company, and alongside Chequers Capital, who will remain a significant shareholder following an initial investment in 2021. The transaction is subject to customary regulatory approval.

Founded in 1974, ESTYA is a leading French services provider specialising in electronic fire safety and security systems with a comprehensive offering across electronic fire detection, smoke extraction and compartmentation, gas detection, and electric security. Headquartered in Paris, the company delivers circa €120m in revenue, across 15 agencies in France, and has tripled in size since 2021, having completed seven acquisitions during that period of time.

ESTYA’s leadership, including CEO and Founder Ludovic Goëta, are committed to supporting the firm’s next stage of growth alongside Charterhouse and Chequers Capital. Through this partnership, and in alignment with ESTYA’s management, Charterhouse will apply its expertise in professionalising, internationalising, and transforming services businesses through organic growth and M&A initiatives across France and other key European geographies.

Charterhouse pursues pan-European mid-market opportunities in two core sectors of focus: Services and Healthcare. It targets businesses that feature ‘defensive growth’ characteristics, combining strong market positions with sustained earnings growth, with the potential for transformation. Its investment in ESTYA is closely aligned with this investment strategy, and follows recent investments in Metrodora, a leading Spanish education group for healthcare professionals, Skin Tech Pharma Group, a B2B medical aesthetics group, and Two Circles, a leading tech-enabled services and software business serving sports and entertainment clients, which were agreed in 2024.

Cédric Barthélemy, Partner at Charterhouse said: “We have been following ESTYA’s journey closely for some time and have been truly impressed by what Ludovic and his team have achieved to date. As a fast-growth, high quality and resilient mid-market company, ESTYA is exactly the type of business that we like to back at Charterhouse. We are delighted to combine our expertise in transforming local leaders in the services sector into international champions with the talented management team and Chequers Capital, to reinforce ESTYA’s leading market position and support Ludovic’s long-term growth ambitions.”

Ludovic Goëta, CEO and Founder at ESTYA, said: “At ESTYA, we are focused on providing mission critical services to our customers across the electronic fire safety and security system value chain. We have grown strongly in recent years and are confident that Charterhouse is the right partner, alongside Chequers Capital, to take us into our next stage of growth across France and into new European markets.”

Aurélien Klein, Managing Partner at Chequers Capital, said: “We are pleased to have found in Charterhouse the right partners to continue Chequers Capital’s investment in ESTYA. ESTYA has grown significantly since we first invested in 2021 and we look forward to working hand in hand with Charterhouse to grow the business further in France and internationally.”
