Augustus

Augustus is building the global dollar bank. Moving dollars across borders still runs on correspondent banking, a chain of intermediaries that is slow, opaque, and expensive. Augustus replaces it with programmable USD and EUR accounts, direct clearing and settlement, and an AI-native core banking platform built from scratch. The moat is the license. Augustus holds OCC conditional approval for a US national bank charter, which is rare and very hard to replicate, and euro clearing is live today for customers including Kraken. $180M Series B at a $1B valuation, led by Tiger Global with QED, plus operators from Nubank, Ramp, Circle, Revolut, and Coinbase. Fewer than 50 people, in NYC and Berlin.
