What ACALY does
ACALY (legal entity: Acaly SARL) is a privately held French engineering consultancy and design office founded in 2015 and headquartered in Lille. The company delivers three core service lines: Consulting (technical and organizational advisory with engineers embedded in client projects), Workpackage (fixed-price project outsourcing with autonomous teams), and Research & Innovation (a dedicated center running thesis work in partnership with engineering schools and laboratories). It serves clients ranging from SMEs to large industrial groups across six sectors: Land Transport, Aerospace/Defense, Energy, Industry, Health, and Telecom-IT.
The company operates through six offices across three countries (France, Belgium, Switzerland) and has grown to approximately 300 collaborators, with the ACALY BENELUX office opened in 2019 and ACALY SUISSE launched on January 1, 2024. The internal R&D unit ACALY LAB was inaugurated on February 28, 2024, focusing on proprietary Industry 4.0 technologies including factory part traceability and production flow optimization. ACALY holds EcoVadis Silver Medal (74/100, 2025) and MASE France and International certification (April 2026).
The business model is professional services revenue — direct sales to enterprise clients with no public pricing. The company emphasizes proximity-based delivery through local offices and leverages a knowledge-sharing network across its talent base of approximately 300 engineers. Notable disclosed engagements include the Project Zénith at McCain Foods' Harnes site and presence at the World Nuclear Exhibition. Growth has been entirely organic, with a stated 41% growth rate and no external funding rounds or parent company disclosed; ownership appears founder-controlled under CEO Tristan Clay.
