Intuit Bought Its Way Into Everything Adjacent to Taxes. Then It Had to Kill One of Its Own.

On October 31, 2023, Intuit told 3.6 million people that the budgeting app they checked every morning would soon stop working, and pointed them somewhere else.¹¹⁷ Mint was not failing in the way that usually kills a product - no scandal, no security breach, no sudden collapse. It simply pointed at the wrong door. Intuit already owned a second consumer-finance app that did a similar job and did it for a reason Intuit liked better. So it sent Mint's users down the hall to Credit Karma and turned off the lights. The decision looked like a cost cut. It was really a confession about how the whole company is built.

The official story is that Intuit is a tax-software company that occasionally buys other companies and wanders into new markets. That reading misses the spine entirely. Intuit doesn't diversify. It annexes the territory next door - and only the territory next door - then routes everyone living there back toward the same two products it started with.

Every acquisition pointed the same direction

Start where the company started. Scott Cook and Tom Proulx founded Intuit in 1983; Quicken shipped in 1984, QuickBooks in 1992.¹ Then in 1993 Intuit used its IPO proceeds to buy Chipsoft, the San Diego maker of TurboTax, for $225 million.¹⁰ Note what that purchase was: not a bet on a new industry, but the obvious neighbor. People who track their money in Quicken file taxes. People who run a small business in QuickBooks file taxes. TurboTax sat in the room next to the core, and Intuit walked through the connecting door rather than across the street.

That is the pattern, repeated for thirty years. Credit Karma, acquired at an announced $7.1 billion in February 2020 and closed in December 2020 for roughly $3.4 billion in cash plus 13.3 million shares and equity awards valued at $4.7 billion, is a credit-monitoring service - which is to say, a machine for understanding a consumer's financial life in detail.³⁴ Mailchimp, closed in November 2021 for about $5.7 billion in cash plus 10.1 million shares worth roughly $6.3 billion, is email marketing for small businesses - the exact customer who already lives in QuickBooks.⁵ None of these were random. Each one is an adjacency: a product whose users overlap almost perfectly with the people Intuit wants in TurboTax or QuickBooks.

Here is the thesis, in one line. Intuit's expansion isn't a portfolio of bets - it's a flywheel, where every adjacent product exists to deepen Intuit's grip on the same consumer and the same small business, and to funnel them back toward tax and accounting. The strategy works precisely because it refuses to wander.

Why the flywheel forced Intuit to kill its own product

A flywheel built on overlap has a hidden tax: it cannot tolerate two products that overlap with each other. And that is exactly what Intuit ended up holding. Mint, the budgeting app it had owned for years, and Credit Karma, the $7-billion newcomer, were both consumer-finance front doors aimed at the same person's wallet.³⁷ Two doors into one room is not a flywheel. It's a fork. Every dollar spent improving Mint was a dollar not improving Credit Karma, and both were chasing the same engagement, the same data, the same eventual handoff to TurboTax.

So Intuit chose. It announced Mint would shut down - first targeting the end of 2023, later extended to March 2024 - and pointed Mint's roughly 3.6 million active users toward Credit Karma.⁷ The detail that exposes the logic: Mint's own founder, Aaron Patzer, said the app had been 'in maintenance mode the last eight years.'⁷ Intuit had stopped investing in Mint long before it announced the closure. The shutdown wasn't a sudden verdict - it was the formal burial of the product that had already lost the internal contest for which front door Intuit would feed.

But hasn't the strategy obviously worked?

The fair objection is that this is too neat a story about a company that is, by any measure, winning. Intuit reported $18.8 billion in revenue in FY2025, up 16%, with Credit Karma alone contributing $2.3 billion at 32% growth.⁶ If the flywheel forced one painful shutdown, so what - the machine is spinning faster than ever. That objection is mostly right, and worth taking seriously. The adjacency strategy is not a failure; it's a high-functioning growth engine, and the numbers say so.

But notice what the Mint episode actually reveals, which is the limit, not the failure. Bundling adjacent products into one flywheel buys you growth right up until two of those products collide - and then the bundle can only resolve the conflict by deleting value it paid for. Mint at its peak — in 2016 — reportedly carried over 20 million users; by the time of the shutdown announcement it was down to 3.6 million active ones, a decline that unfolded under Intuit's own ownership and that Mint's own founder attributed to years of neglect.⁹⁷ That is the cost the headline revenue figure hides. Platform bundling isn't a free lunch where every product makes every other product stronger forever. Past a certain point, coherence demands subtraction. The flywheel grows by adding spokes - and stays a flywheel by occasionally snapping one off.

Intuit spent thirty years and tens of billions of dollars proving a single idea: that the most valuable expansion is the one nobody mistakes for a new business. TurboTax, Credit Karma, Mailchimp - each was the room next door, never the building across town. The discipline is the moat. But the same discipline that made the strategy work is what made Mint expendable. Intuit didn't kill Mint because the budgeting app was bad. It killed Mint because the flywheel only points one direction, and Mint had become a second arrow pointing the same way. In a company built entirely on coherence, redundancy is the one thing that cannot be allowed to survive.
