Stephen Industries

Stephen Industries operates as a Helsinki-based family investment firm dedicated to funding innovative solutions across Healthtech, Deeptech, and Greentech sectors. With roots as an industrial holding company established by accomplished entrepreneur Kustaa Poutiainen, the organization maintains a straightforward yet ambitious vision: achieving unparalleled excellence in their investment endeavors. This commitment to exceptional performance has been woven into the very foundation of the company since its inception, driving their strategic approach to identifying and supporting transformative technologies that contribute to global improvement.

The company's trajectory toward international recognition began with Picosun, a pioneering deep tech venture specializing in atomic layer deposition technology. Founded by Poutiainen in 2004, Picosun exemplifies Stephen Industries' ability to nurture technological innovation into commercial success. Through strategic growth capital investments and expert guidance, the company expanded to generate annual revenues exceeding €50 million. This remarkable growth culminated in the 2022 acquisition by Applied Materials Inc., a leading American technology corporation, marking a significant milestone in Stephen Industries' investment history.

Following the lucrative Picosun transaction in mid-2022, Stephen Industries underwent a strategic transformation, evolving from its traditional industrial holding structure into a dynamic investment company with enhanced capabilities and broader market reach. This pivotal shift has allowed the firm to leverage its extensive operational expertise and industry insights to identify promising early and growth-stage companies developing breakthrough technologies. Their investment approach combines financial support with hands-on guidance, enabling portfolio companies to navigate complex technological and commercial challenges while accelerating their path to market leadership.

Today, Stephen Industries maintains a diverse portfolio spanning multiple sectors, including Puzer, a recognized manufacturer of central vacuum cleaning systems, alongside several innovative technology ventures. Their investments include Hycamite, which develops carbon-neutral hydrogen production technology; TILT, focusing on advanced biometric solutions; Sooma, pioneering non-invasive brain stimulation therapies; Fiberwood, creating sustainable wood-based materials; and Stemsight, developing revolutionary treatments for vision impairment. This carefully curated portfolio reflects the company's commitment to supporting technologies that address significant global challenges while maintaining strong commercial potential and alignment with their expertise in industrial innovation.
