The fund prioritizes energy-efficient, high-performance systems and supply-chain scale-up, representing a deliberate shift from a software focus to investing in physical systems that a16z calls a social and national imperative.

The combined value of a16z’s stakes in the two companies is reported to be north of $8 billion on roughly $320 million of investment.
