Challenge

Tassie is an Amsterdam startup that turns city tourism into something more cultural, more social, and way less cliché. Users explore cities through curated walking routes that mix landmarks, hidden gems, and conversation prompts at every stop.

The business runs on two tracks at the same time. B2C: tourists buy tours directly in the app. B2B: hotels and companies buy access codes and give them to guests or employees to unlock tours for free.

One app. Two completely different users. And at the time neither journey was working well.

The original app had friction at every turn. Redundant buttons showing up where they shouldn't. Unclear states that left users wondering what to do next. A gamification system, points and achievements, that had no clear purpose and confused more than it motivated. Visuals that felt flat and generic for an app targeting young, curious travelers. And for the B2B side? There was no real flow at all, which was a problem because that's the direction the business needed to grow.

Approach

Two weeks. Full-time. Solo.

With that kind of timeline there's no room for extensive research, so I went straight to benchmarking. Airbnb, GetYourGuide, Headout. What do the travel apps that actually convert have in common? Three things came up consistently: large immersive imagery, one clear action per screen, and a tone that feels like a recommendation from a friend rather than a listing from a travel agency.

That became the filter for every decision.

The goal wasn't to reinvent Tassie. The signature red, the playful energy, the Amsterdam soul: those stayed. The job was to remove the noise, clarify the paths, and build a proper flow for each user type so neither one had to navigate through the other's experience.

Low-fi sketches first to map the new flow and cut what wasn't needed. Then wireframes. Then the full UI.

  • Gamification

The gamification system was the first thing to go. Points and achievements only work when users understand what they're earning toward. Here there was no clear reward, no progression, no reason to care. Removing it simplified the navigation immediately.

  • Flow

The B2B flow needed to be completely separate from the B2C purchase experience. A hotel guest receives a code. They open the app, enter the code, the tour unlocks. That's it. Three steps. No payment screen, no sign-up friction, no confusion with how the tourist-facing purchase works. Building this as a standalone path meant both user types could move through the app without running into each other's logic.

  • First Impression

The home screen was the most important screen to get right. Tassie sells curiosity. If the home screen doesn't make you want to explore, nothing else matters. Large photography, a search bar for cities, nearby tours surfaced automatically. The less a user has to think about what to do, the faster they start a tour.

Typography and spacing got a proper system. The red stayed as the primary action color. Everything else was neutrals and photography doing the heavy lifting.

Solution

Here's what shipped.

Onboarding: fast, visual, sets the tone in one screen. One promise, one action, done.

Home: full-width imagery for each tour, city categories, nearby suggestions. Content-first, no clutter.

B2B code flow: enter a code, unlock a tour, start exploring. Completely separated from the purchase flow so hotel guests never encounter a paywall that doesn't apply to them.

My Tours: tabbed between all tours, purchased, and completed. Clear states. No redundant actions.

Profile: compact. Completed tours, saved tours, settings. Nothing extra.

Tour detail: rich imagery, full description, highlights, reviews, and a clear preview vs. buy decision. Everything a user needs to decide without leaving the screen.

Full UI delivered with a refined logo, updated iconography, and a spacing system built to scale.

Results

The founder called it "exactly the vibe we wanted. Modern, visual, and ready to sell."

Hotels responded positively to the new experience. Before the redesign, there was nothing clean to show B2B partners in a demo. After, there was a focused, intuitive flow that made the pitch make sense.

The B2B onboarding became a proper sales tool. The simplified UX gave the team something they could actually put in front of hotel partners and say: this is what your guests will see.

Sometimes good design is not about reinventing. It's about removing what's in the way.

Thirty minutes.

Bring your roadmap and your deadline. I'll tell you whether this is a sprint, a partnership, or neither.
