Early History

Ostrom was founded in January 2021 in Berlin with an objective to simplify the energy switch to renewable sources across Germany. The concept originated when co-founder Matthias Martensen, during his tenure at Oliver Wyman, noticed the outdated and bureaucratic processes dominant in the German energy sector. This realization spurred the creation of an easier, customer-friendly alternative focusing on digital solutions for energy management. The early development phase saw the launch of an MVP (Minimum Viable Product) by May 2021, quickly capturing the attention of consumers due to its flexible offerings of green electricity with no long-term contracts. By the end of 2021, Ostrom had already secured a notable customer base across multiple German cities and proceeded to attract significant early-stage venture capital investments.
