Stephen Industries

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. Read our story to learn more about our background.

For the first 30 years, Stephen Industries operated as an industrial holding company founded by serial entrepreneur Kustaa Poutiainen. 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 catalyzed a change in Stephen Industries’ operations, transforming Stephen Industries into an ambitious and experienced investment company in late 2022. Besides Picosun, we’re currently best known for the central vacuum cleaner manufacturer Puzer and tech ventures such as Hycamite, TILT, Sooma, Fiberwood, and Stemsight.
