Thisbe

Thisbe is a wholly owned subsidiary of FAM AB — part of the Wallenberg family ecosystem — that invests in early-stage growth companies with high levels of innovation and strong potential for long-term value creation. The portfolio consists of around ten companies previously owned directly by FAM, spanning deep tech and climate tech sectors including green hydrogen (Hymeth, Qarlbo Energy), solar and battery technology (Holyvolt), green steel (Stegra), cleantech agriculture (Moving Floor), space infrastructure (Pythom), quantum computing (SEEQC), and sustainable construction (Gropyus). Thisbe takes a close, active ownership approach to support portfolio company development. No public application process or open call for new investments is indicated on the site; the portfolio appears to have been seeded from FAM's existing holdings.
