Summary
Rewbi uses AI to optimize grid-connected battery storage by charging when electricity is cheap and discharging when expensive. Founded by Thomas Marge, a repeat founder who previously founded inBalance (acquired by Stem), and Derek Modzelewski, Adept's first technical hire who worked on early foundation models at Meta. They solve the problem of human traders manually tracking grid conditions despite batteries being able to adjust power output 100x faster than traditional generation and electricity prices changing every 5 minutes by up to 300%. Their AI tracks hundreds of live inputs and makes faster decisions, more than doubling revenue.
