What Zettelwerk AG does

Zettelwerk AG is a privately held Swiss architecture and construction management firm headquartered in Winterthur, Zürich canton. Founded in 2013 and founder-owned by René Zettel, the firm operates as a self-described mittelgrosses Architekturbüro (medium-sized architecture firm) with a lean team of approximately 9–12 members spanning architects, interior architects, visualizers, industrial designers, construction supervisors, and an HR/social-work professional. Its service portfolio integrates project development (Projektentwicklung), architecture, construction management (Baumanagement), construction supervision (Bauleitung), construction consulting (Bauberatung) covering energy, fire protection, and heritage preservation, and 3D visualization/rendering. The firm is positioned as a budget-affine, solution-oriented partner for complex, time- and cost-critical projects in Hochbau (high-rise/commercial), retail, temporary, and office construction sectors across the Winterthur and Zürich region.

The offering is delivered as professional services on a custom project basis, with no publicly disclosed pricing and no standardized product, API, or SaaS component. Technical differentiation rests on an interdisciplinary in-house team — including certified construction managers and a visualization lead with a CAS in Disruptive Technology — rather than on proprietary software. Distribution is direct-to-client project delivery with a single headquarters at Seidenstrasse 27, Winterthur, and a single LinkedIn page as the primary digital presence.

The revenue model is fee-for-service on construction projects. Geographic scope is explicitly Switzerland (CHE) with no claims of international footprint. The firm has no disclosed funding, no external investors, no parent company, no subsidiaries, no acquisitions or partnerships, and no public-sector or large-customer anchors in the source data, indicating an owner-operated consulting model rather than a venture- or PE-backed growth vehicle.
