What Arenit does

Arenit is a German industrial holding company founded in 2016 by Dr. Stefan Niemeier and Dr. Nils Schlag, both former McKinsey senior partners, that acquires and supports family-owned Mittelstand businesses across the DACH region while preserving each company's independent character, brand, and location. The portfolio spans 14+ precision manufacturing brands operating in unrelated niches: f.u.n.k.e. AVIONICS (aviation transponders and avionics, including the RTCA DO-160-qualified TM350), Lampert (PUK 6 fine welding units and MicroArcWelder for jewelry and industrial use), FEMTO (analogue measuring amplifiers such as DLPVA-101), Sobernheimer Maschinenbau/SMB (FKM and UKM sweeper series for municipal and landscaping markets), Denz (precision engineering), Scies Miniatures (miniature saw blades, 60 years in business), Chrosziel (TPA optical quality testing for riflescopes), CAP PARTS (automotive/industrial parts), CNC-STEP (CNC milling machines, 10,000th machine milestone), and AKB (special gearboxes, with US expansion). Revenue is generated through direct B2B sales of industrial hardware across aviation electronics, jewelry manufacturing, municipal equipment, sensors, and machining sectors, with go-to-market anchored on international trade fair presence (GaLaBau, AERO, VICENZAORO, INHORGENTA, SENSOR+TEST, JCK Las Vegas, EPHJ, among others).

Arenit's business model is a long-term permanent-home holding structure rather than a roll-up or PE-style exit vehicle: portfolio companies retain their operational identity while benefiting from shared strategic guidance and capital from the parent. In 2023, Spanish PE firm Portobello Capital acquired a minority stake to support European expansion, and in March 2026 Axon Partners Group was announced as anchor investor for an IPO valuing the group at approximately 120 million euros pre-money, with ~40 million euros in expected gross proceeds intended for further acquisitions and capacity expansion. The holding's offices span Hamburg (legal headquarters), Düsseldorf, Vienna, and Zug, reflecting its DACH-centric operating geography and the cross-border character of the portfolio.

Product overview

Arenit is an industrial holding company that acquires and supports German Mittelstand family businesses, allowing them to remain family businesses while benefiting from shared resources. The portfolio consists of multiple acquired precision manufacturing brands spanning aviation electronics (f.u.n.k.e. AVIONICS), precision welding equipment (Lampert), measuring amplifiers (FEMTO), sweeping machines (SMB), miniature tools (Scies Miniatures), optical testing equipment (Chrosziel), CNC machinery (CNC-STEP), special gearboxes (AKB), and precision engineering (Denz). Rather than a unified platform product, Arenit operates as a decentralized holding structure where each subsidiary maintains its own product identity and operations while benefiting from shared ownership and strategic support from the parent company.
