Star San Duo

What Star San Duo does

Star San Duo is a privately-held Polish partnership company (spółka komandytowa) founded in 2002 and headquartered in Starachowice, Świętokrzyskie Voivodeship. The company designs, manufactures, repairs, and modernizes specialized heavy vehicles for the Polish military, fire services (OSP and PSP), railway operators, and industrial customers. Core offerings include new vehicle design and sales built on chassis from OEMs such as Renault Trucks, custom truck body superstructures (mobile workshops, cargo boxes, dump trucks, cranes, HDS, work platforms, crew buses), comprehensive STAR 266 modernization to the 266M specification using proprietary Zakładowa Dokumentacja Remontowa developed in accordance with manufacturer guidelines, and rail-road dual-mode vehicles certified to PN-EN 15085-2. The company also operates authorized service centers for Jelcz, DOLL, Fassi, Effer, and HIAB brands.

The business model combines project-based hardware sales with professional services revenue. Star San Duo generates revenue through (i) sale of new custom vehicles and verified used vehicles, (ii) design and fabrication of custom truck bodies, (iii) repair and modernization contracts — primarily long-cycle government and military tenders — and (iv) recurring authorized service and maintenance. Pricing is quote-based and not publicly disclosed, with contract values driven by vehicle specifications and scope of work. Direct enterprise field sales is the primary go-to-market motion, supported by a dedicated online sales platform (starsanduo-trucks.com) launched to broaden reach. Customer concentration is heavily skewed toward Polish government and state-owned enterprise buyers; the company cites over 1,300 modernizations and thousands of satisfied customers across Poland since inception. Ownership rests with partners Dominik Pater and Paweł Pater, with no disclosed institutional investment.
