What 50 Ingenieros - Construcción, Fit-Out & Facility Services does
50 Ingenieros Construcciones y Servicios ("50i") is a small, privately held Spanish construction firm headquartered in Madrid, operating across five core service lines: single- and multi-family residential construction, civil engineering projects, urbanization and land development, hotel construction and renovation, and interior fit-out, plus industrial warehouse construction as a project type. The company positions itself as a multidisciplinary team executing unique projects using a fast-track methodology with an emphasis on quality, client proximity, on-time delivery, and value engineering to optimize costs. Geographically, its active project footprint spans Madrid and Sevilla, with all work sourced through direct client engagement rather than third-party channels.
The business model is project-based contracting: revenue is generated through one-off construction contracts scoped per project, with pricing handled via quote rather than publicly disclosed rates. The firm employs approximately 5 people per firmographic data, suggesting a lean model where most execution is likely delivered through subcontracted trades — a typical structure for a small Spanish general contractor. Go-to-market is direct sales via website contact form, email ([email protected], [email protected]), and phone, supported by a modest digital presence on LinkedIn, Instagram, and a project-portfolio website. The company has no software product, no disclosed technology platform, no patents, and no disclosed AI or data capabilities.
There is no publicly disclosed revenue, headcount trend, funding history, or named customer base. The firm participates in Spain's Kit Digital program (funded by EU Next Generation EU mechanisms) and has published a Code of Conduct and Ethical Code as governance artifacts. Ownership, leadership team, and financial history are not disclosed in available sources, leaving significant informational gaps for any external diligence effort.
