Solarize

Solarize provides a cloud-based meter-to-cash billing platform for decentralised energy models such as Mieterstrom (tenant power), GGV community supply, Energy Sharing, on-site PPAs, heat contracting and dynamic tariffs. The website describes an API-first, time-series-based architecture and ISO 27001 compliance.

Its customers are energy suppliers (Stadtwerke), property owners and portfolio holders, and contractors (EVU and Contracting providers). The company sells software for these customers; the website references customer case studies but does not state pricing or revenue model details. It states it serves more than 200 companies and has more than 15,000 meters on the platform (Q2 2026).

Solarize was founded in 2020 and lists offices in Berlin and Stuttgart. The company's open roles include Node.js software engineering, business development representatives, project and onboarding managers for renewable energy, and working-student positions in ISMS and compliance. It names Future Energy Ventures among its partners.
