Eisen, the AI-enabled compliance operations infrastructure for financial services, today announced $18.5 million in funding, including a $10 million Series A led by MissionOG and a previously unannounced $8.5 million seed round led by Index Ventures, with participation from Cowboy Ventures, First Round Capital, Homebrew, and Restive Ventures. The company will use the capital to expand its compliance coverage and grow the team serving fintechs, financial institutions, and digital asset companies.
In 2025, Eisen prevented more than 31% of at-risk assets from being lost to state custody. The company now monitors nearly $16 billion in balances across tens of millions of accounts at nearly 50 companies, including Adyen, Binance.US, BitGo, OKX, and PeoplesBank. The platform integrates state-by-state requirements directly into daily account operations, so institutions can be proactive – catching dormancy risk earlier, replacing manual compliance work, and keeping customer assets in customer hands.
Eisen started with escheatment, where the scale of the problem dwarfs the infrastructure built to handle it. Roughly 33 million Americans have unclaimed property today, with states holding nearly $70 billion in consumer assets (retirement accounts, life insurance proceeds, forgotten savings). In 2024 alone, about $4.5 billion was returned to owners, yet billions more continue to flow out of bank accounts, investment accounts, and crypto wallets each year. Escheatment exists to protect customers. But monitoring hundreds of millions of accounts across 50 states, each with its own rules, is an operational challenge most institutions were never built to handle. Few can keep up.
The problem is accelerating fastest in crypto. California, New York, Delaware, Florida, and a growing list of states now treat digital assets as escheatable property, with most requiring platforms to liquidate dormant tokens – converting customer holdings to cash at prices customers didn’t choose, triggering a tax event they can’t avoid. As the GENIUS Act pulls stablecoins and digital assets deeper into the regulated financial system, the platforms holding them must now comply with state-by-state escheatment rules written without crypto in mind.
“Every dollar in state custody represents a real person who never expected their money to disappear,” said Allen Osgood, co-founder and CEO of Eisen. “The rules governing dormant assets weren’t built for crypto wallets, fintech platforms, or digital-first banking. Most institutions are sitting on 5x to 10x more liability than they realize. Eisen prevents that loss before it happens.”
When funds are turned over to the state, institutions lose three things at once: the assets, the revenue tied to those accounts, and the customer relationship behind them. Consumers lose money they thought was safe. As digital assets and modern financial products collide with legacy state-by-state frameworks, compliance obligations are outpacing the infrastructure most teams have to work with.
“Eisen solves a problem every financial institution, fintech, and digital asset company faces every day – and takes both the operational headache and the regulatory risk off the table,” said Jason Tiede, Managing Partner at MissionOG and Board Member of Eisen. “Allen and the team have built something rare: an AI-enabled compliance system of record, purpose-built for modern financial services.”
Eisen already covers escheatment, tax reporting, and disbursement – and the same pattern shows up across the entire compliance stack. Operational teams use Eisen to replace manual work and prevent dormant-account risk. Executives use it to reduce regulatory exposure, retain customer assets, and protect customer trust.
