Allium Raises $40M to Expand Blockchain Data

Allium closed a $40 million Series B led by Amplify Partners. Kleiner Perkins and Theory Ventures also participated in the round. The startup processes and standardizes onchain data from more than 150 blockchains. Its clients include Visa, Stripe, Coinbase and the U.S. Federal Reserve, the company said.

Total funding for Allium now stands at roughly $61 million. The company said it will use the new capital to expand its data infrastructure and hire engineering and sales staff. Demand for verified blockchain data has grown as financial institutions integrate crypto analytics into compliance, risk management and payment systems.

Allium was founded in 2021 and has positioned itself as a neutral data layer for institutions that need clean, reliable onchain information without running their own nodes. The Federal Reserve has used Allium's data to study stablecoin flows and decentralized finance activity. Visa and Stripe rely on the platform to track merchant settlements and fraud signals across blockchains, according to the company.

The Series B follows a $10 million Series A in 2022. Amplify Partners led that round as well. Theory Ventures, which co-led the latest round, focuses on infrastructure software. Kleiner Perkins has backed other crypto data firms.

Allium's product ingests raw transaction data from major chains including Ethereum, Solana, and Bitcoin, then normalizes it into structured formats. Clients access the data through APIs or dashboards. The company competes with firms like Dune Analytics and Nansen, though Allium emphasizes direct institutional integration over retail-facing dashboards.

A spokesperson said Allium plans to release new tools for transaction monitoring and wallet screening later this year, targeting compliance teams at banks and asset managers.
