Virtual worlds tech firm Improbable, the a16z & Softbank-backed venture builder, has appointed Irina Scarlat, formerly of Uber, Revolut and Bitpanda, as chief marketing officer.

The firm says her expertise in hyper-growth will be central as Improbable sharpens its focus on building and scaling companies at the intersection of AI and Web3.

Improbable is preparing to launch the first ventures built on Somnia, its high performance Layer 1 blockchain, which reached a peak valuation of $1.9 billion following mainnet launch last year.
