Rewbi Closes $4m Seed Round

As we reflect on SF Climate week, we’re excited to announce Rewbi’s $4M Seed round. Rewbi is building the next generation power company, starting with AI to optimize grid-connected battery storage. Over the next decade, Rewbi will enable a cleaner, more affordable and more reliable power grid. We’re starting by facilitating the build out of battery storage through battery rental agreements, as storage becomes an increasingly important part of our grid (see here for one perspective from the WSJ).

Rewbi rents battery storage for a fixed fee per month, and earns more than double that fee in monthly revenue by dispatching the battery optimally. We’re an active power company in Texas, and are already making a profit from balancing the grid. We’re actively quoting battery storage offtake both domestically and abroad, and we would love to connect with project owners to help them secure debt and other project level capital (reach out here to learn more).

Rewbi’s seed investors include Y Combinator, SurgePoint, Aera, General Catalyst, Collab Fund, Climate Capital, Olive Tree, Rebel Fund, Sand Hill North, Orange Collective, Great Wave Ventures, Chris Hopper, Jacob Monroe, Anuj Saigal, Larsh Johnson, Anthony De Vito, Alex Goldstein, Biao Boey, Elizabeth Linardos, William Yu, Benjamin Bryant, Ian Mc Henry, Nathan Woodard, Matthew Verminski, Mohamed Musbah, Jonathan Gheller, Amir Zohrenejad, Sharo Atmeh, Andrew Arkhipov, Lauren Rothwell, Stefan Lederer and more! We’re excited that many of our investors have direct experience in the battery storage industry and see the same opportunities that Derek and I do based on our decade of experience in energy markets.
