Method
How this edition was prepared.
The same process is applied to every company in the source snapshot.
View the official Zefix source01
Start with registered companies
The source snapshot draws on Swiss commercial-register information available through Zefix and associated official register sources.
02
Screen in three Swiss languages
Company names and stated purposes were screened for terms such as Treuhand, Buchhaltung, fiduciaire, comptabilité, fiduciaria and contabilità.
03
Apply a second-stage AI classification
Gemini 3.1 Flash Lite applied a second filter to determine which preselected companies actually provide fiduciary or accounting services. For each company, it considered all available context, including the company name, description and registered purpose. The registered purpose was the main deciding factor.
04
Aggregate and analyze the results
The resulting classifications were aggregated consistently and analyzed by registered canton and city, founding period and legal form. Every chart uses the April 2026 snapshot.
