About Ostrom

Ostrom is a Certified B Corp™ digital energy management platform based in Berlin that makes green electricity affordable and straightforward for households in Germany. Unlike other traditional providers with lengthy contracts, Ostrom offers monthly tariffs, end-to-end English and German support, and electricity at market purchase price, which comes from 100 percent renewable energy sources. Consumers can view their energy consumption and control their tariff in real time using the Ostrom app. In 2023, Ostrom rolled out dynamic pricing and electric vehicle charging integration and its roadmap includes incorporating smart meters and more. All this will support Ostrom in becoming the leading B2C energy platform in Europe by 2030. Ostrom is an equal opportunity company that means it. We have a remote-focused culture built on trust by default.
