What s: stebler does

s: stebler (legal name Kehrer Stebler AG) is a Swiss family-owned manufacturer of custom aluminum and glass building components, headquartered in Oensingen and founded in 1952. The company produces mailboxes and postal distribution systems (Swiss Post-compliant lines such as s: 77, s: 99, s: 75, s: 177/180, and s: box 13), modular parcel locker systems (s: yourbox, awarded the 2019 InnoPrix Swiss Innovation Award), private parcel-and-mailbox units (s: home solution in MONOLITH and FRAME variants), and proprietary management software (s: yours with CLOUD/CONNECT/BASIC subscription tiers). The skylight category spans the s: 203 louver window, s: 211 large-format skylight, s: 211 DA roof access system, and s: 219 flat-roof window with integrated smoke and heat exhaust ventilation (NSHEV/RWA) integrable into KNX and Modbus building automation. The glass facade category is anchored by the patented s: 305 louver glazing system, used in facades, courtyards, roof glazing, and glass pyramids. A Home Living category adds aluminum planter boxes, raised beds, herb ladders, cushion boxes, benches, and outdoor lockers.

The business operates a custom-quote model: each project is individually engineered and manufactured at the Oensingen facility using recycled aluminum and (in s: 203) recycled-PET insulation. Revenue is generated through one-time product sales, in-house installation and mounting services, repair and replacement parts, and a growing subscription stream from s: yours software. Distribution is direct: regional sales representatives cover German-speaking Switzerland, Western Switzerland, and Northwest/Central Switzerland; Kehrer Stebler Germany GmbH (Leipzig, showroom in Berlin) serves Germany and international markets; Kehrer Stebler Portugal Unipessoal Lda. (Lisbon) provides technical support. Customer segments span architecture and planning firms, general contractors, private homeowners, and residential developers, with named reference projects including Glass Trösch Group, Büro Schätz, Vaduzer Landtag, FIPOI, UVEK Campus Ittigen, and Druckerei Wimmis.

Ownership and leadership remain fully in the Stebler family across three generations: Karl and Annerös Stebler founded the lineage, Markus and Anita Stebler assumed full leadership in 2002, and Svenja Lara Stebler joined the Verwaltungsrat in 2018. No external investors or parent company are disclosed. Recent strategic moves include the 2020 Portugal subsidiary, 2023 German subsidiary, 2023 introduction of robotics in production, and the 2025 Berlin Potsdamer Platz showroom, marking a measured but continuous European expansion.
