What VIEROL does

VIEROL AG is a German family-owned specialist distributor and developer of automotive aftermarket parts, headquartered in Oldenburg, Lower Saxony, and founded in 1977 by Jürgen R. Viertelhaus. The company supplies more than 60,000 SKUs across electronic components, engine and transmission parts, emission-reducing components, and electric/hybrid vehicle components through three quality brands: VEMO (electronic components, registered 1998), VAICO (engine and transmission, registered 1999), and ACKOJA (Asian vehicle replacement parts, registered 2016). Its product lines include the EXPERT KITS+ repair-solution kits and the digital EXPERT KIT-FINDER identification tool (launched June 2025). The company holds ISO 9001:2015 certification through DEKRA (recertified in June 2026) and is certified as a TecAlliance Premier Data Supplier (2022).

VIEROL distributes primarily through its own B2B e-commerce platform (vierol-shop.de, relaunched with 30,000+ products in 2022) and via wholly-owned regional subsidiaries in Singapore (VIEROL Asia Pte., Ltd., 2001), Shanghai (VIEROL Shanghai Co., Ltd., 2006), and Warsaw (VIEROL Polska Sp. z o.o., 2023). Its customer base consists of importers, specialist dealers, and independent workshops in more than 125 countries; it serves this base with an enterprise field-sales motion, regional sales teams organized by country and product group, and indirect channel partnerships. Distribution is supported by a 12,500 m² climate-neutral automated logistics center (Werk II, Rastede, opened 2021), a 3,000 m² headquarters, and the VIEROL Academy (opened 2018).

The revenue model is B2B one-time parts sales with quote-based pricing that is not publicly disclosed. Beyond product sales, VIEROL pursues brand-building through motorsport partnerships (DTM since 2024, FK-Performance racing team from 2026), customer/prosumer events (KARLS BUSINESS LOUNGE opened May 2025; Motorworld Global Preferred Partnership effective January 2026), customer magazine (VDRIVE), trade shows (Automechanika), and regional sports sponsorships in Northwest Germany. Under CEO Mirja Viertelhaus-Koschig (since January 1, 2016, succeeding her father who moved to the Supervisory Board), the company describes itself as profitable, capital-strong, and strategically well-positioned, with no external private-equity or venture-capital ownership disclosed.
