Why Mint Died (and What It Taught Us About Free)

In March 2024, Intuit shut down Mint — the most popular personal finance app ever built, with roughly 25 million registered users at its peak — and pointed everyone at Credit Karma, an app that does almost none of what Mint did. The migration dropped budgets and most transaction history on the floor. Millions of people lost a decade of financial records because a spreadsheet in Mountain View said the product wasn't worth the servers.

The interesting question isn't "why did Intuit do it" — companies kill products constantly. The interesting question is why the most-used personal finance app in history was never a good business, because the answer explains most of what's wrong with the category.

Free was the product's defining feature — and its disease

Mint launched in 2007 with a radical price: $0. The model was referral fees and ads — show users a better credit card, collect a bounty when they sign up. It worked well enough to get acquired by Intuit for $170M in 2009, and then it never really worked again.

The problem with monetizing financial data through offers is that your incentives quietly rotate away from your user. The app's job stops being "help you understand your money" and becomes "keep you scrolling past credit card placements." Categorization accuracy — the actual core of a spending tracker — stayed famously bad for fifteen years. There was no revenue line attached to fixing it.

When the user isn't the customer, the product's most important features are the ones the customer (the advertiser) cares about. Mint's users wanted accurate categories. Mint's customers wanted impressions.

The shutdown was the business model completing itself

By 2023, Intuit had a clearer way to monetize the same audience: Credit Karma, an app explicitly organized around financial product placement. Mint's users were worth more migrated into the offers machine than served by a tool whose job was clarity. The shutdown wasn't a failure of the free model — it was the free model's logical conclusion. The audience was the asset; the product was packaging.

This is worth internalizing as a user: a free finance app with no visible revenue source has a business model — you just can't see it from the outside, and history suggests you won't like it when you do.

What the diaspora revealed

The most instructive part of Mint's death was watching where the refugees went. They split along a fault line most people hadn't named before:

• Some wanted Mint, but paid and maintained — full bank sync, budgets, net worth. They went to Monarch and Copilot, and accepted $95–100/yr as the honest price of an app whose customer is the user.
• Some realized they'd never used the budgets at all — they just wanted the "where did my money go" screen. A tool that answers that question automatically, without bank-credential sharing, is the gap Piggey was built into.
• And some went back to spreadsheets, rediscovering within six weeks why they'd left.

The three lessons

1. "Free" in consumer finance means the data is the business. Mint proved the model at scale and then proved its ceiling. The honest alternatives now charge money, which is exactly why they can afford to work for you.

2. Your financial records shouldn't live at a company's pleasure. Mint users lost years of history overnight. Whatever tool you use, prefer one where the underlying data is yours — exportable, portable, ideally derived from files you control in the first place. (A CSV you downloaded from your bank can't be shut down.)

3. The category's core feature was never budgets. Mint's most-loved screen was the pie chart, not the envelope. Twenty-five million people were using a "budgeting app" as a rearview mirror. We wrote a whole essay on that realization — Is Budgeting Dead? — but Mint's usage data made the argument first.

Epilogue

Mint deserves a fair obituary: it taught an entire generation that seeing all your money in one place was possible, and it set the expectation that software should do the sorting. It just never found a way to get paid for being good. The apps that survived it charge money and answer to their users — pick one of those, whichever it is. If your version of Mint nostalgia is "just show me where it all went," that's the part we rebuilt.
