What Firefly AB does

Firefly AB is a Swedish supplier of industrial spark detection, fire prevention, and dust explosion protection systems serving process industries handling combustible materials. Founded in 1973 (as a successor to PAK construction, 1969) and headquartered in Stockholm, Firefly listed on the Nasdaq First North Growth Market in 1997 and now operates subsidiaries in Poland, Italy, and the United States, with a certified distributor and service partner network spanning more than 90 countries. The company's core technology stack centers on patented TrueDetect™ / TrueIR™ infrared spark detectors (FM and VdS certified), Multi-Checkpoint™ detection, water mist and full-cone water suppression systems, the EXIMIO™ distributed control platform with IntuVision™ operator interface, and the more recently introduced Firefly Prediction Solutions (PreSense™ IR trend monitoring, MGD™ multigas detection, TSK temperature monitoring). Vertical-specific branded solutions — PressGuard®, Tissue Solutions®, PlanerGuard™, SanderGuard™, ShredderGuard™, ConveyorGuard™, ElevatorGuard™, IR-Guard™, OvenGuard™, and BakeScan™ — address ten distinct industries including woodworking, wood panel, tissue, pulp and paper, recycling, ports, hygiene, food, power generation, and bioenergy. Firefly's Quick Suppression System (launched 2017) was the world's first third-party approved system of its kind, tested by DFL (ISO/IEC 17025) and verified by DNV.

The company monetizes primarily through one-time capital sales of customized fire protection systems tailored to specific customer process lines (machines, filters, silos, conveyors, ducts), supplemented by recurring service and preventive maintenance (recommended on a six-month cadence by Firefly licensed service engineers), OEM spare parts sales, and repair services. Pricing is bespoke and quote-based rather than published. Distribution is executed through a direct regional enterprise sales organization (three regional Commercial Operations managers covering Nordics/France/Benelux/Africa/Baltics/Middle East/Asia/USA & Canada; CEE/Italy/Greece; and Latin America/Iberia/DACH/UK & Ireland) alongside named country sales managers and certified service partners. Customer logos include Stora Enso, Andritz, Essity, Veolia, Cérélia, Grigeo, Polarbröd, Familia, and Lagge-in-Daio, with an installed base of more than 100,000 detectors globally. Recent strategic emphasis is on shifting from reactive suppression toward predictive fire safety through the 2026 Prediction Solutions launch, expanding large-area suppression via the Automated Water Cannon, and growing aftermarket and service revenue.

Direct peers

• Marioff (Carrier): Developer of HI-FOG water mist fire suppression systems, now part of Carrier. Directly comparable to Firefly's water mist–based quick suppression offering for industrial and process-industry applications, with overlapping customer verticals.
• Fike Corporation: US-based manufacturer of explosion protection (rupture discs, flameless venting, isolation) and industrial fire suppression systems. Overlaps directly with Firefly's explosion protection and special hazard suppression portfolio across process industries.
• Wagner Group (Minimax Viking): German fire detection and suppression specialist focused on industrial and tunnel applications, including oxygen reduction systems. Overlaps with Firefly in industrial process protection and high-risk open-area detection/suppression.
• Minimax (Viking Group): German industrial and special hazard fire protection specialist offering detection and suppression systems for process industries. Comparable product scope (detection plus special hazard suppression) and shared customer base in industrial fire safety.
• GreCon (Fagus-GreCon): German specialist in spark detection, dust explosion protection, and fire prevention systems for the wood, paper, and food industries. Closest head-to-head competitor to Firefly across core verticals, with comparable IR-detection product lines and similar end-customer profile.

Emerging players

• Firetrace International: Specialty manufacturer of automatic fire suppression systems using linear and tubing detection for equipment enclosures and small industrial assets. Adjacent to Firefly's quick suppression offering, focused on smaller-scale and localized industrial risks.
• Janus Fire Systems (Amerex): US-based supplier of clean agent and special hazard fire suppression systems for industrial and commercial applications. Comparable on special hazard suppression technology and overlap in industrial customer segments, though narrower in spark detection.

Broad incumbents

• Siemens (Smart Infrastructure / Fire Safety): Global broadline fire safety and building automation incumbent offering detection panels, suppression control, and integrated building management. Competes indirectly via integrator channels and adjacent automation platforms, with deeper R&D and balance-sheet resources.
• Bosch Building Technologies (Fire Safety): Broad fire detection and voice alarm systems provider with growing industrial safety offerings. Comparable on detection hardware and integrated control platforms but lacks Firefly's depth in process-industry-specific spark/explosion protection.
• Honeywell Building Technologies (Notifier / Gamewell): Large fire alarm and life safety incumbent with industrial and commercial portfolios. Overlaps with Firefly in detection technology and integrated safety platforms, competing as part of a much broader portfolio rather than as a process-industry specialist.
