Future Energy Ventures (FEV) is investing in Solarize. The Stuttgart-based provider of tenant electricity software has brought on one of Europe’s largest venture capital investors in energy tech as a new backer. Existing investors Picus Capital and Point Nine Capital are participating again. The size of the current funding round has not been disclosed.
Solarize operates a cloud-based platform for billing decentralized energy supply and now counts over 200 customers from the energy and real estate sectors. With the fresh capital, the company aims to accelerate technological development and expand access to decision-creaters in the energy market.
Time-series billing as core competency

This solves many of the central challenges of the decentralized energy world,” explains Frederik Pfisterer, founder and CEO of Solarize. The software-as-a-service solution is based on cloud architecture and covers utilize cases ranging from local electricity marketing to dynamic pricing.

Moritz Jungmann, partner at FEV, explains the investment: “Solarize convinced us through its technological depth and holistic vision.”
Positioning as a specialized subledger
Solarize sees itself as a subledger for decentralized energy supply—a specialized system that runs parallel to a company’s general ledger. The focus is on seamless integration into existing ERP systems and general ledger solutions from energy providers. “With FEV, we gain a partner with deep-rooted energy market knowledge and an extensive network,” declares Pfisterer. “Toobtainher, we will establish Solarize as a subledger for the business models of the decentralized energy world and support our customers in scaling their offerings to mass market.”
The meter-to-cash software is designed to enable energy providers and property owners to perform consumption-accurate billing in an increasingly time-series-based energy world. The new funding round aims to further optimize the billing solution for the specific requirements of energy supply companies. “We believe this is a critical moment for investments in digital energy technologies,” declares Jungmann.
The founding trio of Andi Weiß, Florian Feigenbutz, and Frederik Pfisterer operates Solarize from locations in Berlin and Stuttgart. With FEV, Picus Capital, and Point Nine Capital, three specialized VCs back the company, which aims to translate the complexity of decentralized energy systems into standardized billing processes.
