Kartesia backs Verdane's growth bet on Swiss energy-recovery firm Konvekta

What's the deal? Kartesia has provided debt financing to Verdane to support the European growth firm's investment in Konvekta, a Swiss maker of energy recovery systems. The money will fund the transaction and provide additional growth capital, deepening the partnership between Verdane and Konvekta.

What does Konvekta do? Founded in 1949 and based in St. Gallen, Konvekta builds highly engineered energy recovery systems for ventilation and air conditioning in large commercial buildings, with recovery rates of up to 90-95%. It designs its closed-loop systems using proprietary software and digital-twin modelling, and employs about 90 staff across the DACH region, the US, and Asia.

Who's involved? Kartesia financed the deal through its Kartesia Impact Fund and Kartesia Senior Opportunities strategies. Verdane first partnered with Konvekta in July 2025, initiating the succession of the family business.

Why now? Both investors backed the deal from SFDR Article 9 regulated impact funds — Verdane's Idun II and Kartesia's Impact Fund. The transaction marks Kartesia's first dedicated impact investment in the DACH region and its first deal with Verdane.

What's the endgame? The capital is meant to help Konvekta scale distribution globally. "This investment will enable Konvekta as it scales distribution and adoption of this technology globally," said Nico Wellm, associate director at Kartesia.

The signal: The deal reflects a growing convergence of private credit and climate investing, with two established European firms channelling regulated impact capital into a sustainability-focused business. For Kartesia, it signals a deliberate push to expand its footprint in the DACH region.
