    • Ostrom

    Company Overview

    Ostrom GmbH

    Berlin, Germany

    2021

    Over 50 employees (estimated) and over 40 million euros in funding (Source: technews180.com).

    What They Do

    Ostrom focuses on digital energy management for consumers, providing 100% certified green electricity through flexible tariffs such as SimplyFair (electricity at cost) and SimplyDynamic (hourly dynamic pricing based on market rates when renewable production is high). These tariffs are integrated into smart home technology to optimize usage (Source: ostrom.de). Core technologies include app-based control of energy devices, including electric vehicles, home chargers, heating, ventilation, and air conditioning (HVAC), solar inverters, and battery storage. These are enabled through partnerships like the Enode API, which provides a unified interface for tracking consumption and production as well as automatic optimization (Source: enode.com). Products and services include the integration of solar PV for real-time monitoring, smart EV charging that can earn up to 300 euros annually through the NeoGrid™ Virtual Power Plant (VPP), as well as the optimization of heat pumps and the rollout of smart meters (subsidized installations) (Source: ostrom.de). Target markets are households across Germany, with over 100,000 customers expected to be served by 2024, aiming to expand into Europe (Source: technews180.com). Ostrom differentiates itself as a B Corp, certified since March 2023, offering dynamic pricing and one of the largest EV VPPs in Germany (Source: bcorporation.net).

    Projects & Track Record

    Ostrom's flagship is NeoGrid™, the largest virtual power plant for electric vehicles in Germany, launched in 2024. It aggregates household appliances and electric vehicles for grid stabilization and renewable energy integration, allowing users to earn up to 300 euros per year (Source: ostrom.de). Ostrom emphasizes software platforms over physical infrastructure, which is why no specific completed projects with MW capacities are listed (Source: ostrom.de). Ongoing initiatives include the nationwide rollout of smart meters, which are subsidized for access to the SimplyDynamic tariffs (Source: technews180.com). Key partnerships include Enode for device control and Eneco Ventures for strategic growth, with customers primarily consisting of over 100,000 households (Source: enode.com).

    Recent Developments

    In 2024, Ostrom raised 20 million euros in a Series B funding round led by Eneco Ventures to finance the rollout of smart meters and the expansion of the NeoGrid™ VPP (Source: technews180.com). The company launched the largest EV Virtual Power Plant in Germany in 2024, enabling revenue from grid flexibility (Source: ostrom.de). In March 2023, Ostrom received B Corp certification with a score of 147.5 (Source: bcorporation.net).

    Working There

    Ostrom is hiring for positions in Engineering (app development, AI automation, device integration), Product (tariff optimization, VPP technology), Customer Service (live chat, English/German), Marketing, and Operations (smart meter rollout), reflecting the startup's focus on high-performing teams (Source: climatebase.org). Hiring is remote-first from the headquarters in Berlin, supporting all operations in Germany (Source: linkedin.com). The company culture emphasizes transparency, flexibility, results-oriented work, diversity and multiculturalism, as well as lean processes (Source: climatebase.org).
