Money shouldn't come between you.
HeyDuo helps couples track shared expenses, split bills fairly, and stop arguing about money — all with a friendly AI assistant.
Works with Amazon, Walmart, and major banks via Plaid.
Hey! Try asking me:
Money is the #1 thing couples fight about.
It doesn't have to be. The problem isn't your relationship — it's the lack of a clear, shared system.
"Who paid for what?"
Losing track of shared expenses leads to resentment and awkward conversations — even in the best relationships.
"Is this split fair?"
50/50 doesn't work when incomes differ. Couples need flexible, transparent splitting that feels right for both.
"We need to talk about money…"
Financial conversations are the #1 source of relationship stress. Most couples avoid them until it's too late.
You don't need a joint account to manage money together.
HeyDuo is the third option — shared visibility without shared bank accounts. Independence and transparency, not one or the other.
Independent couples
You love each other — not each other's spending habits. Keep your own accounts, share only what matters.
Co-parents
Splitting kid-related expenses after separation shouldn't require a spreadsheet or an argument.
Unequal incomes
50/50 isn't fair when one partner earns twice as much. Split by ratio, not by default.
“Banks give you two options: fully merged or completely separate. We built the one they didn't.”
