Allium Raises $40M Series B as Visa and BCG Build on Its Blockchain Data Platform

Allium, a New York-based blockchain data infrastructure company, has closed a $40 million Series B funding round, bringing its total capital raised to roughly $61.5 million as institutional demand for onchain data accelerates.

Amplify Partners led the round, with Kleiner Perkins and Theory Ventures participating. Amplify partner David Beyer is joining Allium’s board.

The company now manages over 30 petabytes of blockchain data, serving as the onchain system of record for institutions like Visa, BCG, and major banks and asset managers.

Founded in 2021 by Ethan Chan and Cheng Han Lee, Allium was created to solve the problem of fragmented blockchain data across hundreds of chains, making it unusable at institutional scale. Today, Allium ingests raw data from more than 150 chains and over 10,000 protocols, normalizes it into standardized, queryable formats, and delivers it via APIs, data streams, and analytics tools to roughly 150 enterprise customers. Those customers include Visa, BCG, Coinbase, a16z Crypto, Stripe, Uniswap, and Phantom. Allium’s data has been cited by research institutions including the U.S. Federal Reserve and Stanford University.

Revenue grew 10x since its Series A round closed in July 2024. Visa and BCG both built stablecoin dashboards directly on Allium’s platform.

Amplify Partners’ David Beyer pointed to a longer-term opportunity: AI agents using blockchains and stablecoins for autonomous payments and transactions, a use case that depends on high-quality, normalized onchain data.

CEO Ethan Chan connected Allium’s positioning to lessons from machine learning: “You have to control the data source.”

The raise comes as blockchain analytics peers face pressure. Dune Analytics laid off staff in May 2026, and Messari was acquired by Blockworks at a discount in June 2026. Allium has differentiated through its enterprise focus, data quality at scale, and alignment with rising Wall Street participation in crypto, stablecoin expansion, and real-world asset (RWA) tokenization.

“It’s never been a better time for the institutional side,” Chan said.

The company now employs approximately 50 people. Specific allocation details for the Series B proceeds were not disclosed at the time of announcement.
