Diogo Ferreira and Leonardo Berteotti are building BananaSplit. They’ve shipped products together for years. They’ve also been the people in the group chat trying to remember who paid for dinner. Shared money should stay out of the way while you’re together, then be obvious when it’s time to settle.

We’ve used the usual splitting apps for years. They work until they don’t: a 70/30 rent split, a receipt nobody wants to type, a holiday with 20 small payments and one awkward ask.
We wanted something that felt like how friends actually spend — fast to capture, clear to settle, a little more human. So we built it.
We’re a two-person team. We both wear many hats — engineering, marketing, content, campaigns, support, and whatever else needs doing.

Leonardo Berteotti
Leo builds the part of BananaSplit you shouldn’t notice: balances that stay correct, splits that don’t break, and a product that still feels instant when a trip has 40 tiny expenses.
He studied software engineering at ISEC in Coimbra and has been shipping with Diogo since Gymious. At BananaSplit he owns the systems work — reliability, speed, the messy rules real groups actually use.
He likes taking the complicated money math off the table so friends can stay friends.
Diogo is the reason BananaSplit doesn’t feel like accounting software. He works in the overlap of product, design, and engineering, where a split either feels obvious or feels like homework.
He studied Systems Engineering at Minho University and has been shipping with Leo since Gymious. At BananaSplit he focuses on the tap that adds an expense, default splits that match real groups, and screens that show who owes whom without a spreadsheet.
He cares a little too much about the details. That’s the point.
The shared-expense space is crowded. We know that. But after years of trying different apps, none of them quite hit the spot. At the back of both our minds, the same itch kept returning: we could build something better.
