LAUNCHING 2026
02THE PROBLEM

People are overwhelmed by managing money. Too many apps. Too many alerts. Too many things to check.

Good financial behaviour has been taught as vigilance. Checking. Monitoring. Reacting. As if responsibility is a full-time job.

And the tools were never neutral. They are built to profit from your attention, your patience, and your trust.

Complexity is not an accident. It is the business model.

03MISSION

Goodsystemsdon'tdemandattention.Theyremovetheneedforit.

Sumvin is built on a different belief:
that responsibility should be structural, not emotional.

You decide what matters.
You set the boundaries.
The system follows through.

No constant checking. No reacting to noise.
No staying “on top of it” just to feel safe.

When things are set up properly,
attention becomes optional.

Financial freedom no longer needs your full attention.

04ERRANDS

The best way to buy something is to stop watching for it.

An errand holds a purchase open. You name what you want, the most you will pay, and the window it must happen in. The system finds the seller, vets it, and transacts on your behalf. It watches continuously, with nothing running while it waits, and buys the moment your terms are met. It comes back to you only for a decision it is not permitted to make.

Not a saved cart. A mandate.

  1. 01Intent

    what you want, and the conditions it must meet

  2. 02Authorization

    permission to act inside your limits

  3. 03Vigilance

    it watches, and acts the moment your terms hold

05SIGIL

Your Sigil, on a Visa card.

The identity that proves who you are becomes a card you can tap. Same Sigil. Now spendable at every counter that takes Visa.

Visa Intelligent Commerce · Launch Partner

Sumvin is a launch partner on Visa Intelligent Commerce, the rails built for agents that pay.

The card carries your rules with it. The limits you set. The permissions you grant. The boundaries your agent acts within. Wherever Visa is accepted, your authority is accepted with it.

One identity. Every counter. The whole world of finance.

06ENVOY AGENT

An AI agent that handles every money moment. From finding and booking those flights, to rebalancing your portfolio.

Sumvin automatically connects every account, subscription, and service you use. It monitors balances, tracks spending, manages renewals, and flags what matters, without you asking. This is the last money app because it makes the others invisible.
Tell your agent to plan your birthday trip to Rome. It assembles flights, hotels, and a table worth keeping, and shapes them into one itinerary you approve in a glance. You approve the shape. It handles the rest.
The agent runs continuously. It finds better rates on your insurance. Catches duplicate subscriptions. Moves money to higher-yield accounts when it makes sense. Not as recommendations in a notification you'll ignore. As actions, taken on your behalf, within the boundaries you set.
