Company Overview
Rewbi is a technology company founded in 2024 that utilizes artificial intelligence to optimize grid-connected battery storage. The company's service generates revenue by charging batteries when electricity prices are low and discharging them when prices are high, aiming to double the revenue compared to traditional methods. Rewbi's business model involves renting battery storage for a fixed monthly fee and using its AI to generate income from the optimized dispatch of that energy. The company, part of Y Combinator's Summer 2024 batch, was co-founded by Thomas Marge and Derek Modzelewski. Rewbi aims to address grid volatility and support the transition to cleaner energy sources.
