Sorl

Partiful for the Nordics: a live, cross-platform events app I co-founded. I led the brand, design and experience: the part that makes it feel premium and genuinely fun to use.

Facebook still owns events. The Nordics run on Swish and mobile pay. So we built a Nordic take on Partiful, a concept already validated in the US: a great-looking invite in seconds, RSVP with no app install, costs split over Swish. It's a founder project with my co-founder: he built the first version in Swift and we built the Flutter version together. We shaped the business together too, splitting focus, with me leading the brand, the art direction and the experience, plus a good deal of the functionality. Built cross-platform on Flutter; live on the App Store today, with Google Play pending. Honest pin: Sorl has no in-app AI; it's simply a well-made product.

01The bet

A validated concept, a Nordic moat and one friction to remove.

The concept was already proven in the US, so the risk was low. The opening here is local: deep Swish and mobile-pay culture across Sweden, Denmark and Norway, with Facebook events still the default. The friction we set out to kill is the install: guests RSVP and register straight from a link, no app required. A light action feels heavy the moment there’s a barrier in front of it. Removing that barrier is most of the product.

Two Sorl screens: the shareable invite card with Dela and Bjud in actions, and the 'Sorlet är startat' launch screen. Guests RSVP straight from the link, no install.
02What I owned

The brand, the art direction and the details that make it feel like a product.

We built it together, focused on different things: my co-founder on the foundation and the first Swift version, me on making it feel premium and fun. I rebranded it end to end with a new identity and palette. I also built the invite system: gradient backgrounds, ready-made SVG patterns with swappable colors, your own photo or a camera shot, plus GIFs, which are the most fun part and, to me, the differentiator. I shaped the public-versus-private event logic (including how expense-splitting and a behind-the-scenes accountant role work) and added update threads, so a host can broadcast or a group can build a vibe in the run-up. It’s the thesis I bring to everything: make something light feel instant and pleasant, because that’s what people remember.

The Sorl invite builder: a live event card with gradient, pattern, photo and GIF backgrounds, a colour picker and an icon set.
Two Sorl screens: adding a new expense with even, shares, percent or exact splitting, plus the expenses ledger that tallies each guest's share.
Role

Co-founder & builder. We split the work: my co-founder built the first Swift version and leads more of the business; I led the brand, the art direction and the experience. I also built a good deal of the functionality. We built the Flutter version and shaped the business together. A founder side-project, live as a first v1: judge it on the craft and the concept, not on traction yet.
