Company profile
researched Sep 2026Inuru is a Berlin, Germany based company that develops and manufactures printed organic light-emitting diode (OLED) lighting and display technology. Its OLEDs are paper-thin, flexible and described as recyclable, and are produced by a printing process that the company says makes the technology substantially cheaper than conventional OLED manufacturing. The core product is an "elf" (embeddable luminous film), a robust film combining an OLED, a power source and a chip, designed to be laminated, moulded or sewn into other products. The films can display messages, support context-based sensing and user interaction, and are either single-use or wirelessly rechargeable.
The company applies the technology across three stated solution areas: medical packaging ("Medi-Pak") with illuminated warnings and dosing guidance intended to improve medication adherence, clothing with daylight-visible, washable and rechargeable light effects, and marketing/packaging applications for retail, hospitality and home delivery. Its technology has also been described as enabling interactive and reusable packaging, for example integrating displays into containers such as Tetra Paks so they can be refilled and relabelled. Inuru develops its own printed OLED stack and produces devices in Germany.
In March 2024 founders Marcin Ratajczak and Patrick Barkowski opened the company's own factory, the "Dragon Factory", in Wildau near Berlin, where luminous ultra-thin layers are printed onto PET film on a fully automated single production line intended for mass production.
Founding story
Inuru was founded by Marcin Ratajczak and Patrick Barkowski, and originated at Humboldt University in Berlin.
Business model
Inuru manufactures printed OLED films and light-emitting labels in its own German production facility and supplies them to brand owners for integration into packaging, labels, advertising materials and clothing; it also sells finished consumer OLED stickers directly.
Sales of OLED films, luminous labels and integrated light-emitting products to brand customers, plus direct sales of consumer OLED stickers priced at around 20 euros each.
Traction
Named customers include Coca-Cola, Cattier Champagne and Displate. The company delivered an OLED-enabled Coca-Cola Singapore Star Wars campaign in 2019, opened a fully automated production line in 2024, and began shipping a range of OLED-powered consumer stickers in 2024.
Latest developments
In March 2024 Inuru inaugurated its inkjet-printing OLED production line in Wildau near Berlin, and by late 2024 it had started shipping flexible, battery-powered OLED stickers, including a Cyberpunk design range.

Market position
Inuru is positioned as a printed OLED lighting company producing in Germany, distinguished within the packaging sector by low-cost printed manufacturing and named brand references including Coca-Cola, Cattier Champagne and Displate.
Printing-based OLED production that the company says lowers costs by up to 90 percent relative to conventional OLED manufacturing, combined with thin, flexible, recyclable films made from organic emitting materials and integrated power and control electronics in a single film.
Technology
Inuru developed its own printed OLED stack and manufactures it by inkjet printing, depositing luminous ultra-thin layers onto PET film. The resulting "elf" film integrates the OLED with a power source and a chip, is flexible, mouldable, laminable and sewable, and supports free-form light, message display and sensing. The company reports OLED lifetimes of about 5,000 hours, with battery-limited stickers rated to roughly 2,500 activations. It states its printing process cuts production costs by up to 90 percent versus conventional methods and achieves 67 percent energy savings and 99 percent material savings, while avoiding toxic materials by using organic emitters.
Go-to-market
Direct engagement with brand customers, including a sample-request process on its website, alongside branded campaign projects and a consumer product line of OLED "holo tag" stickers.
Consumer brand owners and packaging users in beverages, spirits and wine, cosmetics and champagne, pharmaceutical and medication packaging, apparel, and retail/entertainment marketing; also consumers purchasing OLED stickers.
Geography
Headquartered in Berlin, Germany, with manufacturing at its Wildau facility near Berlin; customer projects have included a Coca-Cola campaign in Singapore.

The company's first project was an OLED-enabled Coca-Cola Singapore Star Wars campaign in 2019. It raised a Series A round in 2020 and a further financing in 2023 backed by Aper Ventures and Adamed Technology, at which point it announced a focus on printed OLED lighting for the medication and entertainment sectors. In March 2024 it inaugurated its inkjet-printing OLED production line, the "Dragon Factory", in Wildau near Berlin, and later in 2024 began shipping a consumer range of OLED-powered stickers.
