Alta builds blockchain infrastructure for banks, payment companies, and other regulated institutions, with privacy and compliance controls enforced on transactions. An early partnership with Airwallex connects the network to local fiat payment rails across 200 countries and 90 currencies, supporting stablecoin transfers, foreign exchange, and treasury management for tokenized assets. The launch targets an estimated $4 trillion held in prefunded accounts globally, cash that institutions keep on hand because cross-border settlement still takes days. The company announced $80 million in total funding, including a $47.5 million Series A led by Index Ventures with participation from GV, Blackbird Ventures, Square Peg, and Capital 49, following $32.5 million in seed financing backed primarily by Airwallex. Co-founders are CEO Loong Wang, who previously co-founded Ren and the quantum chemistry company QDX, president Catherine Porter, who led global partnerships for Meta's Libra initiative, and Airwallex CEO Jack Zhang. Alta's first product is meant to shrink those cash buffers through just-in-time funding and to let businesses move idle balances into yield-bearing tokenized assets. The startup, recently rebranded from Metal, has offices in San Francisco and Melbourne.
