Who are the key investors at Stephen Industries?

What is Stephen Industries?

Stephen Industries is a family-owned investment company based in Helsinki, Finland. We fund companies creating innovative Healthtech, Deeptech and Greentech solutions for a better world. Our vision has been simple since day one: to be the best in the world in what we do. The drive for excellence is deep in the nanofibers of our company. For the first 30 years, Stephen Industries operated as an industrial holding company founded by serial entrepreneur Kustaa Poutiainen. Our journey towards global success started with subsidiary Picosun – a deep tech company that specializes in atomic layer deposition, founded by Kustaa in 2004. Throughout the years, Kustaa raised several rounds of growth capital, growing Picosun to over 50 million euros in annual revenues. In June 2022, Picosun’s stock was sold to US-based technology giant Applied Materials Inc. The sale of Picosun catalysed a change of Stephen Industries’ operations, transforming Stephen Industries into an ambitious and experienced investment company in late 2022. In addition to Picosun, we’re currently best known for the central vacuum cleaner manufacturer Puzer and tech ventures such as Hycamite, TILT, Sooma, Fiberwood and Stemsight.
