What Start Engineering does

Start Engineering AD (Старт Инженеринг АД) is a privately held Bulgarian full-cycle industrial engineering company with approximately 70 years of operational history, 391 employees, and 27,655 square meters of production capacity distributed across 10 branches nationwide (Sofia HQ plus Burgas, Varna, Plovdiv, Stara Zagora, Veliko Tarnovo, plus specialized units for Automation, HVAC, Montage, and Electrical Panels). The company designs, manufactures, installs, commissions, and services electrical, automation, and mechanical systems for large energy, industrial, and transport infrastructure clients. Its core manufactured products include type-tested low-voltage switchgear and Motor Control Centers (PCC/MCC up to 6,300A, separation forms 2/3/4, IP30-54, EN 1090 EXC4 certified), relay panels, control desks, automation panels, and medium-voltage retrofit kits using components from Siemens, ABB, Schneider Electric, and GE. It also operates a CNC metal fabrication shop (laser/plasma/waterjet cutting, FANUC robotic welding) and runs an accredited Inspection Body Type C for electrical installations above 1,000V.

Start Engineering generates revenue through three coordinated streams: (1) engineering and design services delivered via its wholly-owned subsidiary Start Project Ltd. (founded 2005); (2) hardware sales — electrical panels, metal structures, and partner-branded equipment (Phoenix Contact, Lapp Kabel, Circutor, Rittal, Alfra); and (3) installation, commissioning, calibration (Beamex MC6), and inspection services executed by 20+ engineers and 100+ specialists in its Installation branch. A proprietary software layer, SE-DATA, was developed in-house (2020) for seismic monitoring visualization, FFT analysis, and SMS alarm management for dam wall and critical infrastructure monitoring; it integrates with SYSCOM accelerometers and is offered as on-premise or cloud. The company's go-to-market is enterprise field sales driven by official representation agreements with international technology leaders (Siemens, ABB, Valmet Automation, DURAG, Syscom/Bartec, Schneider Electric, ETRALUX), with new business generated through co-bidding and direct relationships with major Bulgarian industrial and government buyers (NRIC, NEK, Lukoil Neftochim, Sofia Metro, Sofia Municipality).

The company's customer base spans power generation/distribution (NEK, Sviloza TPP), transport infrastructure (NRIC for Corridor IV/IX railway electrification, Sofia Metro), oil & gas (Lukoil Neftochim), metallurgy (Promet Steel, Kurdzhali Lead & Zinc), district heating (Toplofikacia Burgas), ports (Burgas Port), industrial manufacturing (Kronospan), and international delivery (Bordeaux Métropole Aréna formwork in France, 27+ Valmet Automation projects across Europe). Pricing is project-based and quote-driven with no public disclosure. Geographic reach is concentrated in Bulgaria with selected European and Balkan spillover through its partnerships. The company is ISO 9001/14001/45001/27001, EN 1090 EXC4, ISO 3834-2, SA 8000, and BDS EN ISO/IEC 17020 certified.
