Allium Raises $40M Series B as Institutional Blockchain Data Heats Up

Allium, the New York-based blockchain data platform, has raised $40 million in a Series B funding round led by Amplify Partners, with participation from existing investors Kleiner Perkins and Theory Ventures. Amplify's David Beyer will join the board as part of the deal.

The raise follows a $16.5 million Series A led by Theory Ventures in 2024, bringing Allium's total disclosed funding to just over $56 million. The company declined to disclose its valuation.

Allium's core product is unglamorous but load-bearing: it ingests, cleans, and standardises onchain data across more than 150 blockchains, then delivers it to enterprises in queryable formats through APIs, analytics dashboards, and data integrations. The company counts Visa, Stripe, Uniswap Foundation, and Phantom among its clients. Its data has been cited by the Federal Reserve and Stanford — an unusual credential for a five-year-old crypto startup.

Since the Series A, Allium says revenue has grown more than 10x. Visa partnered with Allium to power its Onchain Analytics Dashboard; Boston Consulting Group uses the platform for research on digital asset and stablecoin payments. Blockhead has cited Allium data in coverage of stablecoin market share, RWA market growth, and transfer volume — it has become a standard reference point for onchain market sizing.

The company's pitch to investors frames the opportunity around three converging forces: stablecoin supply now sits above $302 billion, onchain payment volume reached $394 billion in 2025, and tokenised financial assets have grown to $27.6 billion.

CEO Ethan Chan, who studied AI at Stanford before co-founding Allium in 2021, said, "Tokenized assets are entering traditional financial markets. Institutions are increasingly building products and workflows on public blockchain networks. As that transition happens, access to blockchain data is no longer enough. Organizations need trusted infrastructure that helps them understand what is happening onchain, operationalize it inside critical workflows, and build products with confidence."

The fundraise arrives as Allium's competitors are consolidating under pressure. Dune Analytics, valued at $1 billion in 2022, laid off 25% of its staff in May. Blockworks acquired Messari last month for more than $10 million — a steep discount to Messari's roughly $300 million peak valuation. Allium has so far avoided the fate of analytics platforms that built for crypto-native users during the bull market without securing the institutional contracts that provide durable revenue.

The company plans to use the Series B to expand its team across engineering, product, and go-to-market roles.
