Key Takeaways
- • Augustus, a federally chartered clearing bank focused on stablecoin settlement infrastructure, raised $180 million in Series B funding at a $1 billion valuation, bringing total capital raised to $210 million to date.
- • The round was led by Tiger Global with participation from Hummingbird, QED, and high-profile fintech founders including Nubank, Ramp, Circle, and Deel principals, plus crypto figures such as former Coinbase CTO Balaji Srinivasan and Circle co-founder Sean Neville.
- • Augustus is positioning itself as a bridge between traditional finance and blockchain infrastructure by building API-first correspondent banking rails that support both legacy settlement methods (Swift, ACH, SEPA) and stablecoin-based payments through its proprietary core banking system, Marble.
- • The company secured conditional approval for a U.S. bank charter in May 2026, targeting access to dollar accounts for international banks and fintechs while enabling 24/7 settlement capabilities through AI-driven back-office operations.

Summary
Augustus, a startup building infrastructure for stablecoin-era payments, closed a $180 million Series B financing round on Tuesday at a $1 billion post-money valuation, according to multiple sources covering the announcement. The round was led by Tiger Global with co-participation from venture firms Hummingbird and QED Investors. The deal also attracted backing from the founders of major fintech platforms—Nubank, Ramp, Circle, and Deel—alongside notable crypto and fintech executives including Sean Neville (Circle co-founder), Balaji Srinivasan (former Coinbase CTO), and Farooq Malik (Rain). Augustus disclosed total fundraising of $210 million to date.
The company's core business addresses a structural inefficiency in cross-border payments: traditional correspondent banking systems operate on weekday schedules with settlement delays, while dollar-pegged stablecoins have emerged as a multibillion-dollar alternative settlement layer that functions continuously. Rather than issuing its own stablecoin, Augustus is constructing an API-first clearing bank that simultaneously supports legacy payment rails—Swift, ACH, and SEPA—alongside blockchain-based stablecoin settlement. This dual-rail approach positions the company to serve both traditional financial institutions reluctant to abandon established infrastructure and modern fintechs demanding faster, always-on settlement.
The infrastructure backbone is Augustus' proprietary core banking system, called Marble, which the company says enables faster settlement, 24/7 operational availability, and AI-augmented back-office processes. The platform supports operating and foreign bank organization (FBO) accounts and is designed specifically around the operational requirements of programmable money and stablecoins. This architecture reflects a strategic bet that stablecoin adoption will accelerate institutional adoption and that clearing banks optimized for this infrastructure will capture correspondent banking market share currently held by traditional operators.
Augustus received conditional approval for a U.S. federal bank charter in May 2026, a critical regulatory milestone that de-risks the path to becoming a chartered clearing bank. The Series B funding provides capital to build compliance infrastructure, expand banking operations, and accelerate charter approval. The investor roster signals institutional conviction: major fintech founders and crypto figures committing capital indicates belief that stablecoin infrastructure is transitioning from speculative to foundational within global payments architecture.
