First Imagine has reaffirmed its support for HotGreen Solutions as the company closes an acceleration round that extends its pre-seed funding. Empirical Ventures is also taking part, and Ponderosa Ventures, part of the Galvanize platform, joins as a new investor. HotGreen also received a non-dilutive Innovate UK Investor Partnerships grant. The funding will support commercial deployments and scaling, mainly in food and beverage, and more pilot projects testing high-efficiency industrial heat in real settings.
