Built for one person. Life happens in groups.

Your flatshare pays rent every month. Your trip group spends thousands in a week. Your team buys lunch, your family runs a gift pool, your couple shares a fridge. Every one of these moves real money. And not one of them can hold a single euro of its own.

Why does every banking app assume one person?

Software is built on a base unit, the smallest thing everything else is made of. For banks and fintech, that unit is the individual: one identity, one verification, one account, one card. Every feature composes upward from the person. It is a clean model, and it quietly decides what the product can and cannot do.

So a group gets faked. A shared tab is really one person fronting the cash and a spreadsheet of who owes what. A joint account is a legal exception: slow to open, tied to named adults, nothing your weekend trip can spin up in ten seconds. The group is always simulated by an individual standing in for it.

Here is the part the model misses. There are more groups than there are people. You belong to many at once: a flatshare, a couple, a family, three trips a year, a team, a gift pool. Count the groups in your life and you pass the number of people in it fast. Each is an economic actor that spends, owes, and settles. None of them has an account.

What if the group were the account?

Flip the base unit. Instead of the individual being the only thing that can hold money, give the group a real account of its own. You do not need a bank charter for every friend group to make that work. You need a neutral rail.

That rail is a stablecoin, a digital coin pegged one-to-one to a real currency like the dollar, settled on a low-cost network. Spliz uses USDC, a fully-backed dollar coin issued by Circle, on Base, the low-fee network built by Coinbase. A group balance clears in seconds, for cents, the same in Paris, Toronto or São Paulo.

With a group account in hand, one question shapes everything: where does the money sit at the moment of the spend? Before it, during it, or after it. Three answers, three modes.

Mode 1, Settle: after the spend (live today)

Settle is the default, and the one you can use right now. Everyone pays on their own as life happens, you log the expenses, and the whole group clears at once at the end. No one fronts the cash, no one chases anyone for it.

• Free to track. Add members and expenses, in your own currency, with 140+ available for display. Nothing crypto on screen.
• One signed consensus. When the group is ready, everyone approves the balances in one tap. It is a shared signature (EIP-712), not an admin deciding for the group.
• One settlement. Then every net balance moves in a single transaction, or none of them does. This is atomic settlement: nobody ends up paid while someone else is still waiting.

The fee is 0.1% taken at settlement, with a $0.10 floor on small amounts, and you see the exact number before you sign. The network fee is covered for you. The contracts are audited, and the balance is non-custodial: your keys stay yours, Spliz never holds your money. This is what is live on iOS and Android today.

Mode 2, Pot: before the spend (next up)

Pot is on the public roadmap, not shipped yet, so read it as a plan rather than a promise. The group funds a shared pot up front. The money lives in the group’s account, not in one member’s, and the group sets the rules: who can spend, what the limits are, how many signatures a payment needs. While it sits, the balance can earn yield, a setting you turn on if you want and withdraw from anytime. The keys stay yours.

This is the thesis at its clearest: an account that belongs to the group, not to one person who happens to be holding the cash.

Mode 3, Card: during the spend (later)

Card comes later, also on the roadmap. It is the group’s shared card. You tap to pay at a merchant, and the spend is split across members at the moment of payment, issued with a regulated partner. No logging after the fact, no settling at the end, the split happens as the money leaves. It is group money for everyday life.

Why it matters

One group, three moments, one balance. Same members, same shared account, the money just sits in a different place relative to the spend: after it (Settle), before it (Pot), during it (Card). The product molds to the group instead of forcing the group to behave like a single person.

The shift is small to say and large to live. Change the base unit from the individual to the group, and the fronting, the chasing and the “we’ll sort it out later” fall away, because the group itself is now the thing that holds and moves the money. To be straight about it: Settle is live, Pot and Card are on the public roadmap. A direction, honestly marked, not a finished product.

One group. Three moments. One balance.
