Zach Dell’s goal is to install a Base Power home battery system in every backyard in America—and in Europe and beyond for that matter—so it’s fair to say there’s a lot of room for growth.

The son of legendary Dell Technologies founder Michael Dell, Zach has already made a name for himself in his own right. Just weeks before turning 30 later this month, his company Base, which Dell cofounded in 2023, has raised another $1 billion in a Series D funding round. The new round revealed that Base’s valuation has spiked to $13 billion from $4 billion in less than a year.

“We want to bring Base to every neighborhood in America over time,” Zach Dell told Fortune, noting that the residential retail electricity market in the U.S. is about $200 billion. “The scale of the opportunity is just massive, and of course, we do have global ambitions. We think markets like the U.K., Germany, Australia, and potentially others are attractive as well.”

The three-year-old company has gone from installing one battery system daily to over 100 per day—more than 30,000 total customers and rapidly rising. Earlier this year, Base opened its own battery manufacturing plant, Base Factory 1, in Austin, and a much larger second factory is under construction and slated for completion in 2027.
