What AAA EDV Vertriebs AG does
AAA EDV Vertriebs AG is a Swiss vertical-software developer founded in 1984 and headquartered in Aarau, building applications for the HVAC and building-services trades (Heizung, Lüftung, Klima, Sanitär). Its product family — the Win line (Win_HT, Win_HT Pro, Win_HT Kühllast, Win_OD, Win_LV, Win_Service) and the newer TAIFUN+ platform — covers heating-load and cooling-load calculation, CRB-compliant specification generation, quotation and invoicing, and field service management, with CAD integrations (Bausoft, TinLine) and BIM data import (IFC, gbXML) layered for interoperability with engineering design tools. The platform is engineered to encode Swiss building standards (SIA norms, MINERGIE, cantonal energy regulations) and Swiss cost structures (CRB), positioning the software as the system of record for Swiss HVAC engineers and installers.
The commercial model combines traditional perpetual software licenses with recurring annual maintenance contracts across the Win installed base of approximately 1,600 licensees, supplemented by paid training and the recently introduced TAIFUN+ subscription tier. Customer reach is concentrated in Switzerland, with indirect cross-sell access to roughly 30,000 app users via the OneQrew construction-software group, of which AAA EDV became a member in 2022. Go-to-market has historically combined direct sales to HVAC engineering offices and installers with distribution through HVAC manufacturers and wholesalers. Disclosed customer satisfaction is 9.1/10 (2022).
Operationally the company remains a focused SME — reported headcount of 12 in 2019 with current activity indicating hiring into the 11–50 band — under the leadership of chairman Christoph Stoica and site/Support head Stefan Antener, with founder Urs Antener and 1988 hire Thomas Widmer preserving multi-decade domain expertise. Recent product investments (TAIFUN+ platform, BIM integration in 2018, Win_Service in 2017, and the HalloPetra AI telephone assistant) suggest an active renewal cycle around a legacy user base rather than a new market entry.
