The company serves two primary customer segments: Polish music festivals and outdoor events (Open'er Festival across all editions, Kraków Live Festival, Orange Warsaw Festival, Polsat SuperHit Festiwal, KFPP w Opolu) and Polish television production (Taniec z Gwiazdami, Twoja Twarz Brzmi Znajomo, Szansa na Sukces, You Can Dance, Mam Talent, The Voice of Poland). Corporate events and industry conferences form a smaller secondary segment. Operations extend beyond Poland into Germany, Czech Republic, Belgium, France, Spain, and Ukraine, though no granular geographic revenue split is disclosed.

GMB Pro Sound generates revenue through project-based professional services contracts, with pricing custom-quoted per engagement based on event scale and technical specifications. Go-to-market is direct B2B relationship-driven sales and industry referrals, supported by a Facebook presence and a portfolio-based company website. The company has 11 disclosed employees, no institutional investors, no parent company, and received a COVID-19 financial subsidy from Polski Fundusz Rozwoju in 2020. No patents, certifications, AI capabilities, or management team details are publicly disclosed.

Broad incumbents

• NEP Group: Global outsourced broadcast and live event production partner serving television networks, sports leagues, and entertainment shows — overlaps with GMB's television production work for shows like The Voice of Poland and Dancing with the Stars.
• PRG (Production Resource Group): Global leader in entertainment and event production services, offering integrated audio, lighting, video, and rigging solutions for concerts, festivals, and broadcast shows — directly comparable to GMB's SOUND+LIGHT+MEDIA service stack, but at much greater scale and geographic reach.

Others

• d&b audiotechnik: German professional audio equipment manufacturer — relevant ecosystem participant as GMB's pro-audio rental fleet likely includes d&b loudspeaker systems for festival and broadcast deployments.
• Meyer Sound: US-based professional sound reinforcement manufacturer — adjacent ecosystem player whose loudspeaker systems are commonly deployed by European AV rental and event production companies.
• L-Acoustics: French manufacturer of professional sound systems and loudspeakers used by GMB and its peers; included as an ecosystem participant because GMB's competitive advantage depends on deploying and investing in this category of pro-audio equipment.

Direct peers

• SFL Group: UK AV rental and event production specialist providing sound, lighting, and video for live events and broadcast — directly analogous integrated service offering to GMB's three-division Grupa GMB structure.
• Solotech: North American AV production services company providing sound, lighting, video, and rigging for live events, tours, and broadcast — closely aligned business model to GMB Pro Sound's equipment-rental-plus-technical-execution model for festivals and televised shows.
• Hawthorn: UK-based live event production and equipment rental company serving corporate events, festivals, and broadcasters — comparable to GMB as a multi-discipline AV production house serving event organizers and television productions.

Regional players

• LS-SYSTEM: Polish audiovisual and event technology rental company providing sound, lighting, and multimedia for corporate events and conferences — comparable regional peer operating in the same Polish market segment as GMB's corporate events work.
• ABAKUS Systemy Audiowizualne: Polish AV rental and event production company offering sound, lighting, and multimedia services across Central Europe — most direct domestic competitor to GMB Pro Sound in the Polish live event market.
