What Stephanie Kasel Interiors does
Stephanie Kasel Interiors is a Swiss interior architecture studio headquartered in Geneva, founded in 2004 by Stéphanie Kasel, a Swiss interior architect trained at prestigious Parisian schools. The firm specializes in full-service, high-end interior architecture for residential and premium commercial clients, offering concept design, material selection (Matérialité), project management, FF&E (furniture, fixtures & equipment) specification, and installation as an integrated turnkey engagement. Projects span scales from 49 m² to 280 m² and are delivered both in Switzerland (primarily the Geneva and Nyon regions) and internationally, with 30+ named projects documented between 2019 and 2025.
The firm's core offering is professional services revenue generated through bespoke, project-based fees rather than a technology platform; there is no proprietary software, API, or AI tooling described in the source material. In early 2023 the firm extended into physical retail by opening La Boutique, a showroom-boutique at Rue Caroline 13, Geneva, selling curated designer furniture and decorative objects from international designers including Kelly Wearstler, Theresa Rand, and Guillaume Delvigne. This creates a second revenue stream (hardware/retail) alongside design services and serves as a physical consultation touchpoint.
Go-to-market is sales-led and relationship-driven, targeting high-net-worth private clients and premium commercial customers. Acquisition channels include a website inquiry form, an Instagram/Pinterest/Facebook/LinkedIn portfolio presence, press coverage and awards, the Geneva boutique showroom, and word-of-mouth referrals within the Geneva HNW community. The firm has no external investors, no subsidiaries, and no parent company; it is founder-owned and bootstrapped, with no disclosed revenue, funding, or headcount expansion beyond 1-10 employees.
