About Delta Green

• Delta Green was established in 2008 as Nano Green and rebranded in 2024 by David Brozik, Prokop Cech, Lukas Benes, and Jan Hicl. 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.
• According to Delta Green, its solution makes possible to integrate renewable resources into the grid on a massive scale without compromising grid stability. Additionally, the startup can save or earn hundreds of euros annually for households equipped with photovoltaics, batteries, heat pumps, or electric vehicles. 

As our initial move, we’re introducing the service to Czech households, aiming to aggregate tens of megawatts,

David Brožík, Delta Green’s co-founder, said.

Investment details

• Tilia Impact Ventures is the lead investor during the €2.2 million round. It is a Prague-based seed stage venture capital firm. In September 2023, the firm launched its second €30 million fund, to support mission-driven CEE founders in climate, education, and healthcare.
• The investment round also saw participation from Credo Ventures, a Czech early-stage investor, and Purple Ventures, a Brno-based VC fund, which also invest in tech startups across the Central and Eastern European region.
