What Gosan Tech does

Gosan Tech Co., Ltd. is a privately held South Korean company founded in December 2015 and headquartered in the Baekseok Industrial Complex in Cheonan, Chungcheongnam-do. The company manufactures precision inkjet manufacturing equipment for OLED displays, perovskite solar cells, semiconductors, and bio-medical applications, organized around two proprietary technology pillars: micro-pressure control (preventing nozzle clogging and improving ejection uniformity) and nano-ink circulation stirring (enabling precise jetting of low-dispersion-stability inks). Its product portfolio comprises three inkjet system series — Pulse (compact desktop R&D), Wave (glove-box N2 environment), and Beat (multi-layer RGB patterning for perovskite and display production) — plus five modular components (Inkjet Head Module, Ink Supply Pressure Controller, Micro Pressure Controller, Ultra Inkjet Pressure Controller, and Head Suction Module). The company reports achieving the world's first shipment of perovskite solar cell inkjet equipment (June 2022), a self-sensing embedded inkjet system (September 2021), and development of a 1100x1300mm fifth-generation perovskite panel maker (November 2023).

The company operates a direct B2B, custom-quote sales motion to enterprise manufacturers and research institutions globally, with an 18-hour quote-response SLA disclosed on its multilingual (Korean/English/Chinese) website. Equipment systems reportedly sell in a $70K–$150K+ band per project depending on specifications, supplemented by bespoke R&D collaborations with universities and institutes. Revenue derives predominantly from hardware sales of systems and modules, with secondary revenue from custom equipment engineering services. The customer base spans Samsung Electronics (primary partner since March 2021), ETRI, Gyeongsang National University, and various R&D institutions, distributed across the semi/display/perovskite/bio verticals with no single end-market dependent concentration.

Gosan Tech has progressed through Series A (2019), Series B (2020), and a strategic round led by Global Brain with Epson participation (April 2025). Strategic technology relationships with Epson (printhead supply, KM1024MHE/Dimatix/Samba/SG024), KRICT (Daejeon resident company since March 2025 with Dr. Jeon Nam-jung), and ETRI (QD patterning co-development) anchor its R&D, while a Cheonan City Green Mobility Talent Agreement and TH Pharm MOU (August 2024) extend its vertical reach into pharmaceuticals. The company has secured ISO 45001, INNO-BIZ, IP Management, and G-PASS certifications, alongside recognition in the Korean Ministry of SMEs and Startups' Materials/Parts/Equipment Startup 100 program.

Core offering

Gosan Tech manufactures and supplies precision inkjet printing systems and modular components for OLED displays, perovskite solar cells, semiconductors, and bio-medical applications. Its product lineup includes the Pulse, Wave, and Beat (MERAK) series inkjet systems, plus modular components such as inkjet head modules, pressure controllers, and head suction modules. The company's offerings are differentiated by proprietary micro-pressure control and nano-ink circulation stirring technologies that improve deposition accuracy, enable diverse ink compatibility, and reduce material waste by over 70% compared to spray and rub methods.

Product overview

Gosan Tech is a South Korean inkjet technology company offering three series of inkjet systems (Pulse, Wave, Beat) and five types of modules (Head Module, Ink Supply Pressure Controller, MPC, IMS, Head Suction Module). The systems serve applications in semiconductor manufacturing, perovskite solar cells, OLED/display production, and bio-medical industries. Core technologies include micro pressure control preventing ink from clogging nozzle surfaces, and ink circulation stirring for precise discharge of low-dispersion stability inks. The Wave Series operates within nitrogen glove boxes for oxygen/moisture-sensitive processes, while the Beat Series targets multi-layer RGB patterning for perovskite solar cells. All systems incorporate proprietary pressure control technology and nano-ink circulation capabilities.
