I have a theory, and it goes like this:

Convenience built the original bank bundle.

Back in the day, five products from one institution beat five branches, five sets of paperwork, and five relationships to manage. But then digital distribution came along and broke that advantage. Once consumers could open accounts from the couch, fintech companies could peel off checking, savings, lending, investing, and advice one product at a time.

We can call that era The Great Unbundling.

With The Great Unbundling, convenience became portable. Now, almost any company can place several products behind one login, which makes convenience a weak differentiator (but also a necessary foundation). No rewards program is rich enough to make a branch appointment feel modern.

Once convenience stopped being enough, consolidation needed a payoff: a better rate, lower fees, or richer rewards.

For the customer, that means less coordination and a better deal. Triple cherry jackpot. For the provider, it requires much more coordination behind the scenes. The economics of one product must support another, a task that can feel surprisingly exotic inside a large bank whose business lines share a logo and, well, little else.

Banks have an advantage here. Deposits fund loans, and the spread can subsidize generosity elsewhere. Up to a point, the bundle pays for itself. More products reduce acquisition costs and raise customer value. Past that point, the customer gets an annual fee and a guide promusing up to $6,000 in value (provided she treats perk redemption as a second job!).

That's the limit of pricing and rewards. They can make a bundle more valuable today, but they won't answer the larger question of what all those products are supposed to accomplish together for consumers.

That brings us to outcomes.

Money exists to help people get somewhere, be it a house or room in the budget to cover a broken transmission. A bundle organized around that destination gives consumers a reason to consolidate, a reason that can outlast any promotional rate or airport lounge perk.

It also asks for more trust. You can judge an app in an afternoon and inspect rewards at month’s end. You can't know in 2026 whether a financial system will produce a comfortable retirement in 2056. By then, the appeals process is fairly limited.

The customer must trust the provider long before the outcome can prove the provider right. Until then, the customer can judge only the process: what the provider recommends, why, and who answers for it.

That makes an outcomes-based bundle far more expensive for the provider to deliver. The best recommendation may cost revenue by telling the customer to pay down debt, maximize an employer match, or leave the money where it is. The provider must also document that advice and put someone qualified behind it.

Outcome-based bundles give consumers the strongest reason to stay, while testing whether the provider can afford to keep that promise.

The cycle follows from there. Convenience held the original bank bundle together. Digital distribution made convenience portable, opening the door to The Great Unbundling. Pricing and rewards gave consumers a reason to bring products back under one roof. Outcomes give them the strongest reason to remain there.

The old bank bundle survived because leaving was inconvenient.

The new fintech bundle survives only if the pieces work better together than they do apart.
