Czech energy tech startup Delta Green has raised €2.2 million to expand its operations into Western Europe and further develop its energy management solution for households. The investment was led by Tilia Impact Ventures and saw participation from Credo Ventures and Purple Ventures, as the startup shared with Vestbee.
- Delta Green was established in 2008 as Nano Green and rebranded in 2024 by its founders, David Brozik, Prokop Cech, Lukas Benes, and Jan Hic. The startup develops technologies and software solutions to make flexible electricity consumption accessible to households, promote renewable sources, and reduce emissions from power plant operations.
- Plzen-based Delta Green aims to integrate households into grid balancing, potentially saving or earning hundreds of euros annually. The startup’s solution, which includes photovoltaics, batteries, heat pumps, and electric vehicles, is expected to be completely operational by year-end.
"As our initial move, we're introducing the service to Czech households, aiming to aggregate tense of megawatts, As Delta Green expands into Europe, they'll be handling hundreds of megawatts. That's why it's crucial to develop a robust and stable solution now, which will help replace fossil fuel sources with electricity that's currently being wasted in households. They estimate they'll only need about 200 households per megawatt,” Co-founder at Green Delta, David Brožík, stated.
Details of the deal
- Tilia Impact Ventures, a Prague-based seed stage venture capital fund, led the investment. It launched its second fund, raising €30 million to support mission-driven CEE founders in climate, education, and healthcare.
“In order to clean up the carbon footprint of our energy sector, we need more renewable sources on the grid. But wind and sun are unpredictable and this creates energy fluctuations which must be balanced out , Delta Green has developed a low-cost solution to this problem, and we believe that this could be a key puzzle piece in enabling more renewable energy generation and lowering the cost of electricity for everyone. We're excited to partner with them in taking this global,” General Partner at Tilia Impact Ventures, Andrew Gray, commented.
- The investment round saw participation from Credo Ventures, a Czech early-stage investor that funds tech founders from the CEE region, and Brno-based VC fund Purple Ventures, which invests in startups across the CEE region.
- Delta Green plans to develop its sustainable energy management program for homes, grow its team mostly in the field of software development, and enter new markets in Western Europe.
