Eisen, an AI-powered compliance operations infrastructure provider for financial services, has closed $18.5m in combined funding to tackle a growing and largely underserved regulatory challenge facing banks, FinTechs, and digital asset platforms.
The total raise comprises a $10m Series A led by MissionOG, alongside a previously undisclosed $8.5m seed round led by Index Ventures. Additional backing came from Cowboy Ventures, First Round Capital, Homebrew, and Restive Ventures. The company intends to deploy the capital to broaden its compliance coverage and expand the team working with financial services clients.
Eisen’s platform embeds state-specific dormancy and escheatment requirements directly into the day-to-day account management processes of its clients, enabling them to identify dormancy risk earlier and reduce reliance on manual compliance procedures. In 2025, the company prevented more than 31% of at-risk assets from being transferred into state custody. It currently monitors nearly $16bn in balances across tens of millions of accounts at close to 50 firms, including Adyen, Binance.US, BitGo, OKX, and PeoplesBank.
The problem Eisen addresses is substantial. Approximately 33 million Americans have assets sitting in unclaimed property, with states holding close to $70bn in consumer funds — spanning retirement accounts, life insurance proceeds, and dormant savings. In 2024, around $4.5bn was returned to rightful owners, yet billions more continue to exit bank accounts, investment accounts, and crypto wallets annually without reaching their owners.
The challenge is becoming particularly acute in the digital asset space. States including California, New York, Delaware, and Florida now classify digital assets as subject to escheatment rules, with many mandating that platforms liquidate dormant tokens at market prices the customer did not select — creating unavoidable tax consequences in the process. As the GENIUS Act draws stablecoins and digital assets further into the regulated financial system, platforms holding those assets must navigate state-level escheatment frameworks that were not designed with crypto in mind. When assets are remitted to the state, institutions simultaneously lose the assets themselves, the associated revenue, and the underlying customer relationship.
Eisen began with escheatment but has since expanded to cover tax reporting and disbursement. The platform serves both operational teams seeking to eliminate manual compliance work and senior executives looking to manage regulatory risk and protect customer retention.
Eisen co-founder and CEO Allen Osgood said, “Every dollar in state custody represents a real person who never expected their money to disappear. 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.”
