Rewbi has raised $500K in total across 1 funding round.
Rewbi uses AI to optimize grid-connected battery storage. We generate revenue by charging when electricity is cheap and discharging when electricity is expensive.
We rent battery storage for a fixed fee per month, and we earn 2x that fee in monthly revenue by dispatching the battery optimally.
Today, power companies use human traders to manually track grid conditions and update the battery’s dispatch schedule. However batteries can adjust their power output 100x faster than traditional power generation (e.g. hydro, coal, nuclear, gas), with the ability to go from full-speed charging to full speed discharging in under a minute. Electricity prices change every 5 minutes, often by 300% or more. Our AI better tracks 100s of live inputs, and it makes decisions faster than a human operator (with lower overhead!), improving revenue 2x.
Rewbi is a climate tech startup founded in 2024 that uses artificial intelligence to optimize grid-connected battery storage systems, effectively doubling the revenue generated from these assets. Its AI technology intelligently charges batteries when electricity prices are low and discharges them when prices are high, maximizing financial returns for battery storage project developers and operators. Rewbi rents battery storage capacity for a fixed monthly fee, offset by the optimized revenue generated through AI-driven dispatch. The company primarily serves power companies and battery asset owners, addressing grid volatility and enhancing the reliability and efficiency of renewable energy sources while reducing reliance on fossil fuels during peak demand periods. This positions Rewbi as a key player in accelerating the transition to clean, stable energy storage solutions[1][2][3][4].
Rewbi was founded in San Francisco in 2024 by Thomas Marge and Derek Modzelewski. Thomas, the CEO, has extensive experience in battery dispatch and renewable energy optimization, having previously founded inBalance, a Y Combinator-backed company acquired by Stem, Inc. Derek, the CTO, brings deep expertise in machine learning from his work at Meta and other AI-driven ventures. The idea for Rewbi emerged from their combined decade-long collaboration and recognition of the inefficiencies in manual battery dispatch in energy markets. Early traction included joining ERCOT, the Texas grid operator, as a registered power company, validating their technology and business model in a major energy market[1][3][4].
Rewbi rides the accelerating trend of integrating AI with renewable energy infrastructure to address grid instability and carbon emissions. The timing is critical as electricity markets become more dynamic with increasing renewable penetration, causing price volatility that traditional manual battery management cannot efficiently handle. Market forces such as regulatory support for clean energy, rising demand for grid reliability, and the falling costs of battery storage favor Rewbi’s AI-driven model. By enabling more profitable and reliable battery storage, Rewbi influences the broader ecosystem by encouraging investment in clean energy assets and advancing the modernization of power grids globally[1][2][3].
Looking ahead, Rewbi is poised to expand its footprint by partnering with more battery storage developers and grid operators, leveraging its AI to capture growing market opportunities in energy storage optimization. Trends such as increasing renewable energy adoption, electrification, and grid decentralization will further amplify demand for intelligent battery management solutions. Rewbi’s influence may evolve from a technology provider to a key enabler of grid modernization and decarbonization, potentially expanding into financing and maintaining clean energy assets as indicated by their broader mission. Their ability to scale and sustain double revenue generation will be critical to maintaining competitive advantage and driving long-term impact in the energy transition[1][4][5].
