Sunday, for Performativ

Wealth software is built for the advisor.

The client — the person whose money it actually is — sees almost none of it. A statement, a number, a quarterly call. But they’re the one who has to trust it, and that trust is a design problem.

I’m Carl. I run Sunday, product design for fintech, ex-Swedbank. I kept circling the screen the client should see, so I designed my take. It’s live, just below.

The concept, running

It’s live. Open any holding for the detail.

How I’d make the client trust it.

I mapped what a high-net-worth client actually wants from the screen — and it isn’t more data. It’s three quiet answers: are we okay, what happened when markets moved, and is anyone minding this. Performativ has all of it. It just lives on the advisor’s side. So I designed the client’s.

Open. The client opens it on their phone, between meetings — not at a desk.

Four decisions, and why:

Total wealth

€48,412,000

+€1,214,000+2.6% this yearOn plan

I led with the answer, not the data

A client doesn’t open their portfolio to study it. They open it to ask one thing — are we okay. So the screen opens with the number and a plain “on plan,” not a wall of charts.

This year

Spring drawdown — shown as handled, recovered by May.

I showed the scary moment as handled

Trust isn’t built by hiding the bad quarter. It’s built by showing the spring drawdown — and that the plan held and recovered. The honesty is the feature.

Private markets20%€9.7M

I put the money in plain language

Where it is, in words a person actually uses — public equities, private markets, cash — not asset-class jargon. One tap goes to the depth, for the day they want it.

Two things need you this quarter. The rest, Maria already handled.

I kept the human in it

Private wealth is a relationship. The advisor stays a real person with a face, and only the two things that genuinely need the client ever surface. Calm by default.

Anyone can render a portfolio. The work is making the person whose wealth it is feel calm.

A bit about me.

I’m Carl. I run Sunday, a product-design studio for fintech. Before this, Swedbank, one of the Nordics’ largest banks. I work embedded, like part of the team, from first research to the final interface. No handoffs.

I built this from the outside, on your product and your positioning alone. No access to your data, no brief. With your real custodians and client data behind it, it gets a lot sharper.

“He champions user-centered design without ever losing sight of how it drives real business outcomes. That balance is rare.”

Joackim Zwahlen — UX Lead, Swedbank

That’s the idea.

I made this because the problem stuck with me. If it’s useful, grab 30 minutes below and I’ll show you where I’d take it next. If you want it real, a two-week sprint makes this screen production-ready with your data. If not, no hard feelings. I’ll be watching what you build either way.
