Cloud&Heat closes financing round with INVEN CAPITAL successfully

May 9th, 2017

Cloud&Heat Technologies GmbH, specialist in the area of water cooled data center solutions and experienced expert in the operation of secure Cloud solutions receives new capital. The financing round is being led by INVEN CAPITAL, a subsidiary of Czech energy provider ČEZ. Also, VNG Innovation GmbH, a 100 percent subsidiary of Leipzig VNG – Verbundnetz Gas AG, which already invested in the Saxon start-up at the end of last year, increases its investment in Cloud&Heat in the current financing round.

“We are very proud to have closed this financing round successfully and to have found an experienced strategic partner in INVEN CAPITAL“, says Nicolas Röhrs, CEO of Cloud&Heat Technologies GmbH. “With the new substantial capital, we will expand our market position, realize newly won projects faster than planned and do first steps on international terrain. Concrete talks have already been held with interesting partners from Japan and Scandinavia. Our future focus lies on the USA,“ explains Röhrs further.

“With our investment in Cloud&Heat Technologies we are further developing our activities in the decentralized energy space and smart solutions for customers. We expect that this investment will broaden our IT know-how while at the same time being deployed in the heating sector where we are proficient. The ČEZ Group has acquired a minority stake including an advisory board seat,” Daniel Beneš, CEO of ČEZ comments on the investment.

Based on own energy and cost-efficient hardware, Cloud&Heat develops and implements individual data center solutions and cloud infrastructures. The highlight: Thanks to an energy-saving water cooling, the waste heat from the servers is efficiently dissipated from the heat hotspots and used to heat real estate. “With our innovative water cooling system, we can dispense with other cooling systems and significantly reduce the operating costs of data centers equipped with our servers. At the same time, a large amount of CO2 can be saved – this is not only economically profitable, but also makes a great contribution to environmental protection,” says Röhrs.

The involved parties have maintained silence about the size of investment.
