Blockchain data startup Allium raises $40M Series B as institutional interest in onchain analytics grows

Blockchain data startup Allium has raised $40 million in a Series B funding round led by Amplify Partners, with participation from Kleiner Perkins and Theory Ventures amid increasing demand for onchain analytics services.

Allium ingests, cleans, and standardizes onchain data across more than 150 blockchains, making it queryable for financial institutions, developers, and analytics platforms. Clients include Visa, Stripe, Coinbase, and a16z crypto, and the U.S. Federal Reserve has cited the company's data, according to an announcement.

Allium previously closed a $16.5 million Series A in July 2024, which was led by Theory Ventures and brought total funding to $21.5 million at the time. The Series B brings total disclosed funding to roughly $61.5 million, Fortune first reported Tuesday. The New York-based company declined to disclose its valuation.

The round comes as the broader blockchain analytics sector has consolidated under pressure. Dune Analytics, which was valued at $1 billion in a 2022 fundraise, cut 25% of its staff, and Blockworks acquired Messari for more than $10 million in a steep discount to Messari's approximately $300 million valuation from the same year.
