⚡️ About Ostrom

Energy. Just Better.

Ostrom makes switching to green energy as economical and as effortless as possible for households in Germany.

Ostrom offers just one flexible monthly tariff, end-to-end English & German support from the website to the live customer care chat, and only purchases 100% green energy. We upend all the headaches of the German energy industry where 12 to 24-month lock-ins, non-existent customer service and paper & fax-based backend processes are the status quo.

The norm for energy contracts in Germany is to lure customers with a large upfront discount but a long lock-in period which they hope to automatically extend by another 1-2 years - giving traditional utilities a lock-and-forget incentive. By offering users simplicity and flexibility, Ostrom is aiming to push the green energy transition further.

In the future, Ostrom sees the increasing adoption of smart meters & electric vehicles as further areas of opportunity to increase our scope.

👨💻 About the Founders

The idea for Ostrom came from Matthias during his time advising energy companies at Oliver Wyman. Upon seeing how manual and bureaucratic everything was - such as 90% offline marketing budgets to highly manual backend processes, he decided to leave and pursue creating a better energy utility for Germany around December 2020.

Karl joined several weeks later to help with the user acquisition & UX, having previously worked in several B2C startups and was also on the lookout for founding a startup after joining the Berlin cohort of Entrepreneur First.

After a few months of development the early MVP was released on May 2021 and we have been already serving several customers while continuing to refine our product and operations.
