Augustus has secured $180 million in a Series B round, reaching a $1 billion valuation, to expand its mission of providing financial institutions worldwide with programmable access to U.S. dollar accounts and payment rails.

The round was led by Tiger Global, with participation from QED Investors, Hummingbird VC, Brevan Howard Digital, existing backers, and founders of Ramp, Deel, Nubank, and Circle.

The funding follows Augustus' recent conditional OCC approval for a U.S. national bank charter, supporting its vision of building a Global Dollar Bank powered by its AI-native banking platform, Marble.
