The team building the system of record for onchain finance

We started Allium in late 2021 to close a data gap we had spent our careers working on. Today we are 50+ engineers and operators across New York, Singapore, and remote, backed by a $40M Series B.

Our story

Origin

We came from data infrastructure

Ethan led ML and data engineering at Primer, building realtime systems for Fortune 500 companies and governments. Cheng Han led cloud and payments engineering at Poynt, processing billions of dollars, and built ad data infrastructure at Meta. Finance was moving onchain and would need the same kind of foundation.

Problem

Openness delivered as chaos

Public blockchains promised open data and produced something fragmented and inconsistent, impossible to treat as a record. Every serious analysis began by rebuilding the same brittle plumbing: RPC connections, mismatched schemas, chain reorgs. All of that before anyone could answer a basic question with confidence.

Solution

One canonical source

We ingest raw blockchain events across 150+ chains, then verify and reconcile them into finance-ready datasets: 10,000+ decoded schemas, standardized, queryable, auditable. The plumbing becomes our problem.

Today

The system of record, in production

Visa, Stripe, Phantom, Coinbase, Uniswap, and Grayscale run analytics and mission-critical workflows on Allium. The unglamorous part, the reconciliation and the edge cases, is the part we care most about.

Named to the Future 50

In 2024 The Generalist asked leading investors to nominate the startups with the most potential, capped at a $200M valuation. We made the 50. We have raised a $40M Series B since.
