Blockchain data startup Allium closed a $40 million Series B on June 23, 2026, with Amplify Partners leading and Kleiner Perkins and Theory Ventures participating, as Visa and the U.S. Federal Reserve use its on-chain data in institutional products and research.
The round brings total disclosed funding to roughly $61.5 million, including the $16.5 million Series A that Theory Ventures led in July 2024. Theory backed both rounds, while Kleiner Perkins joined the Series B.
The New York company ingests, cleans, and standardizes on-chain data across more than 150 blockchains for banks, fintechs, analytics platforms, and government agencies. Its client list includes Visa, Stripe, Coinbase, and Andreessen Horowitz's crypto arm. The U.S. Federal Reserve has also cited Allium data in published research.
The raise points to a shift in how traditional finance uses crypto infrastructure. Banks and asset managers are no longer treating crypto only as an asset-allocation question. They also need reliable blockchain data for payments, compliance, analytics, and internal reporting. Allium sits in that data layer.
"It's never been a better time for the institutional side," CEO and co-founder Ethan Chan told Fortune.
The round comes as other crypto analytics firms face pressure. Dune Analytics laid off staff, while Messari was acquired at a significant discount to its prior valuation. Allium has pitched itself around data quality for institutional compliance and AI workflows. Amplify Partners' David Beyer pointed to AI agents settling transactions in stablecoins as a potential source of demand for clean on-chain data feeds.
