Thank you to @WSJ for covering the launch of Base Core and our $1B Series D.

The U.S. is undergoing a foundational shift in energy demand, and traditional power generation can't scale fast enough to meet it. Meeting demand this fast calls for new technology that works alongside the grid and adds capacity where it's needed most.

Base Core does just that: one of the largest home batteries on the market at 39.2 kWh, designed and built by Base in Austin, and engineered for rapid deployment at scale.

This new capital will go toward bringing Core to more homes, expanding nationally, and hiring exceptional talent.

The Series D is led by @RibbitCap, Addition, Valor Equity Partners, and @jpmorgan’s Strategic Investment Group, with participation from @AltimeterCap, D1 Capital Partners, Sands Capital, @coatuemgmt, Layer Global, and @EnergyImpact_ . Base’s major existing investors are re-investing, including @ThriveCapital, @a16z, @lightspeedvp, Trust Ventures, @CapitalG, and more.
