Stripe-Backed Tempo Raises Massive $500M for Blockchain Payments
Tempo, a payments startup propelled by Stripe, just closed a record $500 million Series A to build a new blockchain-based payment infrastructure. The investor list surprisingly includes VCs typically focused on AI and enterprise software. It's a clear signal of the convergence between AI-driven agentic finance and crypto payment rails.
The massive $500M Series A for Tempo, which came with a $5 billion valuation, was led by Greenoaks and Thrive Capital, with notable participation from Sequoia Capital, Ribbit Capital, and SV Angel. Interestingly, as incubators, neither Stripe nor crypto-focused VC firm Paradigm contributed new capital to this round. Tempo is a new, independent company led by Matt Huang, the co-founder of Paradigm, who also sits on Stripe's board. The project was born out of Stripe's need for a high-throughput, low-latency blockchain specifically for payments, as CEO Patrick Collison noted that existing blockchains didn't meet their requirements for large-scale stablecoin use. The blockchain is a Layer 1, meaning it's not built on another network like Ethereum, and is designed specifically for stablecoin transactions. It aims for a throughput of over 100,000 transactions per second with sub-second finality, a stark contrast to Bitcoin's sub-10 TPS. It also features "dedicated payment lanes" to ensure transaction fees remain low and stable, even during network congestion. This move is part of a larger, billion-dollar crypto strategy from Stripe. The company previously acquired Bridge, a stablecoin infrastructure startup, for a reported $1.1 billion, and Privy, a crypto wallet provider. Tempo completes this stack, giving Stripe control over the entire stablecoin transaction lifecycle. The project has attracted top talent, including Ethereum core researcher Dankrad Feist, and is being developed with input from a wide range of major players in finance, e-commerce, and AI, including Visa, Shopify, Deutsche Bank, OpenAI, and Anthropic. The long-term vision for Tempo is explicitly tied to the rise of AI-driven agentic economies. Stripe anticipates a future where software agents transact directly with each other at machine speed, requiring infrastructure that can support potentially over a million transactions per second. This positions Tempo as a foundational layer for a new wave of automated, machine-to-machine commerce.
