What gfai tech does

gfai tech GmbH is a Berlin-based (Berlin-Adlershof) specialist in acoustic and vibration measurement and visualization, founded in 2006 and wholly owned by the GFaI research society. The company builds both hardware and software for high-precision sound source localization, with beamforming-based Acoustic Camera systems at the core — ranging from handheld units (Mikado) to stationary arrays such as the 192-microphone Octagon and customized installations exceeding 500 microphones. Its proprietary NoiseImage software suite offers a modular platform covering near-field holography, pass-by measurement, wind tunnel analysis, psychoacoustics, and order analysis, alongside structural dynamics products including the WaveHitMAX automated impact hammer, WaveCam video-based vibration analysis, WaveSim FEA software, and QAIros industrial quality testing. The newest line, HydroVision SeaStar24, extends beamforming into passive underwater acoustic imaging for maritime security and critical infrastructure monitoring.

Revenue is generated through a mix of hardware sales (microphone and hydrophone arrays, data recorders including mcdRec and the new gt4 series), modular software licensing (NoiseImage Basic plus add-on modules), engineering services (consulting, custom hardware/software development, rental, calibration), and turnkey customized solutions (e.g., up to 1,000-hydrophone arrays, 40-meter-diameter geometries). GTM is sales-led and event-driven: direct enterprise field sales with consultation-based quoting, supplemented by trade show presence (UDT, BeBeC — which the company itself hosts), webinars, technical publications, and a small e-commerce shop for standardized services like WaveCam analysis.

The customer base spans automotive manufacturers and research institutes (primary segment), rail operators and regulators (Federal Railway Authority, DB Regio), energy and wind turbine OEMs (Siemens Energy, Flender), academic and industrial R&D centers (Tongji University, RWTH Aachen), and a nascent marine/defense vertical. Pricing is quote-based and not publicly disclosed. The company employs 11–50 people, has not raised venture funding, and operates as a privately held, parent-owned Mittelstand specialist rather than a venture-backed growth company.
