Rebaba has raised $44.0M in seed funding, a hefty early-stage bet on giving used electric vehicle batteries a second act. The company builds energy storage systems from repurposed batteries, aiming to smooth the path toward a greener grid without the environmental cost of manufacturing new units from scratch.
The round’s size stands out for a seed stage, signaling strong conviction in the market for circular battery solutions as utilities scramble for cheaper, more sustainable storage options. Rebaba’s pitch hinges on turning a looming waste problem-retired EV packs-into a grid asset, though specifics on backers or deployment plans remain under wraps.
