Definitely a cool & smart company
Got stuck during application on an offer with another bigger popular energy company, as I was already with them, due to a bureaucratic blocker on their online formular even their customer service did not want to understand....... well this blocker does not exist with Ostrom: totally another level and they are quick, after 2 days they managed to switch on my contract, which includes dealing with Stromnetz.

Hi Goutham,
Thank you for your honest feedback, and we're sorry this experience left you frustrated. We understand how important the invoice is for your insurance claim.
We looked into your case right away. You reached our support team via chat in the Ostrom App on the same day, and our agents worked on your request. We currently don't offer phone support, which is why you couldn't find a number. Chat and email are the fastest ways to reach us.
Why we couldn't issue the invoice immediately: as your energy provider, we can only bill based on the official readings of your electricity meter, not on values from the drying company's devices alone. The readings we received didn't match your meter's history, so we had to double-check before creating an invoice. We're sorry this wasn't made clearer from the start.
We'd love to solve this with you. Please continue the conversation in the chat in the Ostrom App, and we'll work out the best way to document the consumption for your insurance.
Feel free to contact us with any further questions or visit our FAQ [https://support.ostrom.de/en/] for more information!
Best regards

Recommend!! Top electric service provider.
This service provider has been one of the best I’ve encountered since arriving in Germany in 2022. It has always been a smooth experience with very competitive rates and no hassle. The English app made the entire process much easier. I have not had a single complaint about the company.
