What Construction21 does

Construction21 is a Swiss specialized recruitment agency operating as a brand of Prime21 AG, focused exclusively on permanent placement (Feststellenvermittlung) in the construction and technical sectors. Its coverage spans architecture, technical & service, building management, building technology (Gebäudetechnik/HLKS), construction management, and real estate. The company serves both employers and job-seeking specialists in German-speaking Switzerland, with offices in Zug (headquarters, Bahnhofplatz 6300 Zug) and Zürich (Löwenstrasse 1, 8001 Zürich), and operates across the Zürich metropolitan area, Innerschweiz, and Zentralschweiz regions. Its core methodology is direct candidate outreach (Direktansprache) — accessing passive candidates not reachable through conventional job boards — supported by a curated candidate pool and salary benchmarking.

The commercial offering is structured across three tiers: success-based permanent placement (Best Effort), exclusive full-service mandate recruitment, and the PrimeExcellence subscription, which adds modular PeopleSearch, PeopleLearning & Development, and PeopleCare services on a recurring basis. Pricing is undisclosed publicly; a CHF 750 referral bonus program is operated for candidate recommendations. Distribution is relationship-driven — direct employer consulting, a self-service job portal, and email/phone contact channels — rather than performance-marketing-led. Construction21 operates within a broader Prime21 AG multi-brand portfolio that includes Prime21 (IT), PrimeSelect (Search & Select), Care21 (healthcare), HR21, GetTemp (temporary staffing), and Payflow (payments), but Construction21 itself does not disclose financial data, headcount, or ownership stakes, and is treated as a privately held brand under the holding entity rather than an independent investable company.
