Founded

Size

What They Do

Lumenaza GmbH is a Berlin-based software company that develops a comprehensive SaaS platform for the electricity market. This platform helps utilities, aggregators, and energy companies connect decentralized producers and consumers, manage market processes, and launch white-label energy products (source: linkedin.com, lumenaza.de, wikipedia.org). The platform offers an end-to-end solution integrating features such as billing, balancing group management, CRM, customer portals, market communication, product catalogs, redispatch, electricity trading, and virtual power plants (source: lumenaza.de). Lumenaza positions itself as a software company for green, decentralized energy, aiming to optimize the connection between producers and consumers of green energy while reducing time-to-market and costs for its customers (source: lumenaza.de, lumenaza.de). Its target customers include municipal utilities, new market entrants, and larger energy providers such as EnBW and E.ON (source: lumenaza.de, linkedin.com).

Additionally, under the LUOX Energy brand, Lumenaza operates its own direct-to-consumer offerings, which since July 2024 include dynamic electricity tariffs and direct sales of decentralized generation at market prices. This development demonstrates the company’s dual role as both a software platform provider and a market-oriented energy service brand (source: lumenaza.de).

Projects & Track Record

Lumenaza has established itself by providing its SaaS platform to several prominent customers in the German energy market. For example, Greenman Energy uses the Lumenaza platform to supply German supermarkets and charging stations with photovoltaic power (source: lumenaza.de). The platform also supports SonneNext’s market expansion through energy aggregation and dynamic tariffs (source: lumenaza.de). Furthermore, Lumenaza is an associated partner in the SISSY research project, which optimizes and tests processes for direct sales (source: lumenaza.de). The platform enables a wide range of market processes, contributing to the digitalization and decentralization of the energy industry.

Recent Developments

In July 2024, the LUOX Energy end-customer brand was realigned to focus on dynamic electricity tariffs and direct sales of decentralized generation (source: lumenaza.de). Throughout 2024 and 2025, Lumenaza released numerous updates on topics such as dynamic tariffs, solar market expansion, smart meter rollout, the Energy Hub Alliance, and the opportunities of direct sales under the German "Solarspitzen-Gesetz" (source: lumenaza.de). In March 2025, Lumenaza joined the SISSY research project as an associated partner to optimize direct sales processes (source: lumenaza.de). In April 2025, it was announced that Greenman Energy is using the Lumenaza platform to supply supermarkets and charging stations with PV power (source: lumenaza.de).

Working There

Lumenaza offers diverse career opportunities, especially in software development, energy market operations, sales, marketing, product management, and business operations. Public job listings include roles such as Junior Operations Manager, Head of Sales DACH, Operations Team Lead, and Senior Marketing Manager, highlighting the company’s broad scope (source: lusha.com, linkedin.com). The headquarters are located in Berlin-Kreuzberg, recognized as a central hub for developing digital solutions in the energy sector (source: lumenaza.de). The company culture emphasizes advancing the digital energy transition, developing software for decentralized energy, and collaborating with municipal utilities and new market entrants across Germany and Europe (source: lumenaza.de, linkedin.com, xing.com).
