What Killer Interior Ag does
Killer Interior AG is a Swiss family-owned company, founded in 1936 and headquartered in Lupfig, Canton Aargau, that designs, produces, and installs customized shop fittings and interior build-outs for commercial clients. The company delivers a fully vertically integrated service covering conception, design, planning, project management, production, logistics, and assembly across 4,000 m² of production space and 4,000 m² of warehouse at a purpose-built facility opened in 2018. Its core operating differentiator is the proprietary Killer Lean Management system and the supporting Killer Lean Academy, which combine 5S workplace organization, video and spaghetti-diagram analyses, and KVP continuous-improvement workshops to drive efficiency and Swiss-quality craftsmanship. Sustainability is operationally embedded: 1,428 rooftop solar panels generate approximately 400,000 kWh annually, covering 100% of the company's electricity needs, and waste heat from production is reused via concrete-core tempering and a groundwater-fed heat pump.
The company sells exclusively to enterprise B2B customers via direct project-based engagements, with no public pricing or product catalog. End customers include Swiss and international retail chains (Jelmoli, Vögele Shoes across 70+ locations, Lindt & Sprüngli with international rollouts in Budapest, Belgrade, Paris, and Brno, Läderach), banks (Raiffeisenbank Kaisten), gastronomy and hospitality (Hans im Glück), and pharmacies and drugstores. The company works alongside design and architecture partners such as Mint Architecture AG, Liganova, Mach Architektur, Brem+Zehnder, and interior designer Kurt Merki Jr. on flagship concepts. Reported 2025 revenue was CHF 33.4 million at the standalone level (+0.6% YoY, the ninth consecutive year of growth excluding the 2020-2021 Covid period) and CHF 45.6 million at the group level including the recently acquired k design&build ag (+4.8%). The company is led by Chairman/Owner Marco Killer and CEO Thomas Würtenberger, employs 112 people, and is investing in a five-story, 12,680 m² expansion of the Lupfig facility that broke ground in September 2025 and is scheduled for completion in spring 2028.
