Unclaimed funds API for fintechs

Find the money your users forgot they had.

One API call checks state unclaimed-property records against every address your user has lived at, then keeps checking. Your app delivers the good news, and the reason to come back.

What it does for your business

The rare notification users are glad to get.

Fintech apps send a lot of messages about bills, balances and fees. "You have money waiting" is a different kind of moment, and it repeats.

Retention

A reason to stay

Every state refresh is another chance to tell users something new. Monitored users have one more thing to lose by leaving.

Engagement

Alerts that get opened

Found-money alerts get read. Claim steps bring users back to check progress, and dormant accounts get a reason to log in.

Acquisition

Lower cost to acquire

"See if you have unclaimed money" is a sign-up offer with real value and no discount. People tell friends when an app finds them money.

Trust

100% to your users

No finder fees, no cut, no upsell. Returning someone's own money is something they remember your brand for.

Where it shows up in your app

Five moments, one integration.

Features

Built for production, not a search box.

Address history

Past addresses with date ranges, so we match both the state and the years a record was reported.

Confidence tiers

High-confidence matches are ready to show. Medium ones come back as "Is this you?" for users to confirm.

Continuous monitoring

We re-check monitored users when states publish new records and send a webhook for anything new.

State claim steps

Online thresholds, documents, notary rules and deep links to each state's official claim page.

Grouped results

Several matches in one state come back as one summary, ready for a single notification.

Official sources

Records from state unclaimed-property programs, refreshed on each state's own schedule.

Add-on · Settlement matching

Your transaction data, matched to settlement payouts.

Class-action settlements pay people who bought from a company during a set period, and most never claim. If you hold card transactions, we check them against open settlements and tell you which users likely qualify, for roughly how much, and by when.

Ready for the assistants and tools your team already uses.

Your in-app assistant

If your app has a chat assistant, it can answer "Do I have money owed to me?" by calling our tools directly, with the user's consent.

Your developers

Docs, sandbox and test identities available inside your engineers' coding tools, so integration takes hours.

Your support team

Agents look up a user's match and claim status from the tools they already work in, with no new dashboard.

Who it's for

Any app that knows its users and wants them back.

Consent and compliance

Built for the review your compliance team will run.

We designed the product around how unclaimed property actually works in each state.

Built by a team from finance and technology.

Consent firstEvery scan needs a consent record from your app. Every request is logged.
No SSN neededName, date of birth and address are all we use.
Users claim freeDirectly from the state. We never charge consumers or file on their behalf.
Official recordsState programs and licensed address sources. Live in the largest states, rolling out to all 50.
