Allium raises $40M to enhance blockchain data for Wall Street
The New York-based data platform is building the infrastructure layer that traditional finance needs to actually use blockchain technology.
Allium, the enterprise blockchain data company that counts Visa, Stripe, and Fidelity among its clients, has raised $40 million to deepen its push into Wall Street’s growing appetite for on-chain analytics.
The raise marks a significant leap for the New York-based startup, which closed a $16.5 million Series A just last July. That round, led by Theory Ventures, brought total funding at the time to $21.5 million.
The Bloomberg terminal problem
The company provides production-grade indexing, APIs, and analytics across more than 150 blockchains. It takes the raw, messy firehose of on-chain activity and turns it into structured, queryable datasets that institutional clients can actually use.
Allium offers millions of labeled addresses and over 100 on-chain data schemas, covering everything from real-time decentralized exchange trades to fraud detection patterns. The company holds SOC 1 and SOC 2 certifications, which are the table-stakes security audits that institutional clients require before they’ll even take a meeting, let alone sign a contract.
Why Wall Street cares now
Allium’s data was featured in Citi’s 2025 report, which projected stablecoin transactions approaching $1 trillion per month.
Visa is using blockchain rails for cross-border settlement experiments. Stripe re-entered the crypto payments space. Fidelity has been building out digital asset custody and trading. All three are Allium clients. The common thread is that each of these institutions needs reliable, compliant, institutional-grade data infrastructure to operate in the on-chain world.
The client roster also includes the Uniswap Foundation, which bridges Allium’s appeal across both traditional finance and crypto-native organizations.
The competitive landscape
Allium isn’t the only company chasing this opportunity. Firms like Chainalysis, Nansen, and Dune Analytics all operate in adjacent spaces, though each with different specializations. Chainalysis leans heavily into compliance and law enforcement. Nansen focuses on wallet labeling and smart money tracking for traders. Dune built a community-driven analytics platform that’s popular with researchers and crypto-native teams.
Founded in 2021, the company has moved quickly from seed stage to institutional credibility in roughly four years. The earlier funding came from notable venture firms including Kleiner Perkins and Amplify Partners, both of which have deep networks across enterprise software and fintech.
