After finding growth in its home market and Poland, Czech Republic-based Woltair has raised venture capital to expand its software platform for heat pumps and PV systems, used by both installers and homeowners, into Germany and Italy.
Czech Republic-based Woltair is expanding into Italy and Germany, after setting up its online heat pump and solar PV business in the Czech Republic and Poland. The growth takes advantage of the housing market’s switch to heat pumps and the adoption of solar energy on roofs. It entered Germany and Italy after raising €20.5 million ($22 million) venture capital round last year from European and North American investors.
Woltair offers a web-based platform used by private consumers and small and medium-sized installers. Homeowners use Woltair’s country-specific websites to enter their home’s heating needs, for example to get recommendations and prices for heat pump setups from different manufacturers, while experienced installers use the workflow software, called Superfix, to manage customer orders and installation projects. . Buyers and technicians are connected on the platform.
“Together with our investors, we believe that even a subject as complex as the purchase and installation of heat pumps and photovoltaic systems can be digitalized and that many process steps can be automated along the way to provide a great experience for both consumers and technicians in the market. ” shared CEO of Woltair, Vít Javůrek pv magazine. “Our mission is to accelerate Europe’s energy transformation, and heating in particular, in residential buildings by making the heat pump adoption process as simple, smooth and efficient as possible.”
Consumers can compare different brands and products to find “the best solution” for their home, a feature that sets Woltair apart from platforms that have only a limited number of suppliers, Javůrek said. The company also provides financing, develops its heat pump brand and operates its own warehouses.
The company has reportedly served more than 3,000 customers in the Czech Republic and Poland. It recently raised €20.5 million from existing and new investors, in addition to the €16.3 million raised in September 2022. The new capital will be used to strengthen its position in the heat pump and PV supply chains, and to finance expansion into Germany and other countries. Italy.
Noting that there may be a need for some “portfolio adjustment,” along with marketing tailored to “local realities and customer needs,” Javůrek said collaboration in individual markets with local teams will help drive product development.
The venture capital round was led by US-based investors The Westly Group, an existing investor specializing in cleantech, and Fifth Wall, a new investor specializing in real estate technologies. Other early investors participated in the round, including early-stage investor KAYA, Czech Republic-based Inven Capital, and Canadian cleantech investor ArcTern Ventures.
