Why We're Building Vaulra

My partner and I tried to budget together once. It lasted about two weeks.

We sat down on a Sunday, opened a shared spreadsheet, and mapped out everything: rent, groceries, utilities, savings. It felt productive. We were finally going to get our money organized.

By the second week, the spreadsheet was already wrong. One of us forgot to log a grocery run. The other entered a number in the wrong column. We spent more time fixing the spreadsheet than actually talking about money.

So we tried apps. The popular envelope app. The aggregation-focused one. A few others. They were good at what they did, but they were all built for one person. The moment we tried to use them together, we hit the same wall every time: share everything, or share nothing.

That was the part that never made sense to me.

The all-or-nothing problem

When you share a budget with someone, most apps give you two options. You can merge everything into one view, where both people see every dollar, every transaction, every account. Or you can keep completely separate budgets and try to coordinate manually.

Neither option reflects how most households actually work.

My partner and I split rent. We share grocery costs. But we also have personal spending that is, frankly, none of each other's business. A birthday gift. A hobby purchase. A random impulse buy that does not need to become a conversation.

We wanted to share the things that are shared and keep the things that are personal. That is not a complicated idea. But no app we tried could do it.

Why existing tools fell short

It is not that existing budget apps are bad. The envelope method is solid. Transaction aggregation is useful. But these tools were designed around a single user's financial picture.

Sharing was added later, as a feature, not as a foundation. And when sharing is an afterthought, it shows. You get full transparency or nothing. You get one shared login or two separate accounts with no connection between them.

There is no way to say: share the rent envelope and the grocery envelope, but keep my personal spending private. You cannot give someone view access to certain budget envelopes while letting them add expenses to others. Moving money from your personal budget into a shared household budget means tracking it in two places.

These are not edge cases. This is how most couples and households actually manage money.

The decision to build

I kept waiting for someone to solve this. A budgeting app where sharing is built into the design, not bolted on. Where "together" does not mean "transparent about everything."

Nobody built it. So I started building it myself.

Vaulra is a budget app based on the envelope method. You set up your budget envelopes once, and that structure carries forward each month. Income comes in, gets allocated across envelopes, and expenses are tracked against each one.

That part works for one person. The part that makes Vaulra different is what happens when you add someone else.

What Vaulra is trying to do

Shared Budgets in Vaulra are independent from your personal budget. You create a shared budget, invite someone, and define exactly what they can see. Which envelopes are visible. Whether they can edit or just view. Whether they see income entries or just spending.

Each person has their own visibility profile. Your partner might see the rent and grocery envelopes but not your personal savings. A roommate might only see the utilities envelope. A family member might have view access to everything but edit access to nothing.

And when you contribute money from your personal budget to a shared one, it happens as a single transaction. One entry creates an expense in your personal budget and income in the shared budget. No double-entry. No reconciliation.

This is what budgeting looks like when sharing is part of the foundation, not a feature toggle.

What comes next

Vaulra is still being built. I am building it in public, which means the progress is real and the gaps are honest. Some things work well today. Others are still in progress.

The company behind Vaulra is one human making the decisions, supported by AI agents that handle the work. That is a story for another post. For now, the thing that matters is the product and whether it solves a real problem.

If you manage money with a partner, a family, or a household, and you have felt the friction of the all-or-nothing choice, Vaulra is being built for you.

More soon. If you want to follow along or try Vaulra when it is ready, join the waitlist.
