Success Story · End-to-end product build

Quitty — rethinking expense splitting

Quitty is a German-first, premium expense-splitting app for friend groups, couples, flatshares, and travel companions. The name carries a double meaning: quitt sein — being even, all settled — and Quittung, the word for receipt. We are taking this product from market analysis and positioning through brand, screen design, and technical foundation.

Our role on this success story

Success stories on this site are not just portfolios of shipped features — they show how we think, structure, and deliver product work. Quitty is a particularly complete example of that.

Full-cycle ownership on Quitty

On this project, we own every phase of the product and business development cycle — market analysis and positioning, product vision, brand and design, technical architecture, and the roadmap through delivery.

Joining ongoing work

Not every engagement looks like Quitty. We also step into processes that are already underway — a product mid-build, a repositioning in flight, or a technical foundation that needs clearer direction.

Towards the bigger picture

Whatever the entry point, we help teams see and deliver towards the bigger picture — connecting isolated tasks to a coherent product story, business model, and execution path.

Product goals

Every design and engineering decision is measured against what users should be able to do effortlessly — not feature count, but moments that feel obvious at the restaurant, on a trip, or at home.

  • Create a new group easily
  • Add expenses in seconds
  • Split by item at the table
  • See who owes what at a glance
  • Invite guests without an account
  • Stay DSGVO-compliant by default

Screen design

Early high-fidelity mockups for core flows — groups overview, trip detail, members, and adding an expense.

How we work on this project

The six phases below map how we are building Quitty — from competitive landscape and business model through brand, screens, infrastructure, and delivery. Each phase is documented as the project evolves.

Quitty

Here we run the full cycle: strategy, product definition, design, and engineering direction sit with us — not as handoffs between vendors, but as one continuous thread.

Other engagements

On other engagements we join at a single phase or several — for example refining positioning, designing core flows, or shaping architecture for a team already in build.

Bigger picture

In every case, the goal is the same: make the next decision clearer and keep delivery aligned with where the product and business need to go.

Phase details

Collaborative item claiming

The payer opens a receipt to the group; each member taps what they ordered — live at the table or async. Unclaimed items split equally as fallback.

Instant split — no account needed

A single-use feature at the table: scan or enter a bill, share a link or QR code — everyone picks what they had and sends their share. No group, no account required.

Bot members & identity

Add named placeholders before someone has an account. When they join Quitty and claim their slot, all historical expenses transfer automatically.

European hosting & DSGVO

All infrastructure hosted within Europe. Full Datenschutz-Grundverordnung compliance from day one — no US cloud dependencies for user data.

Platform & access

Quitty is designed as an iOS-first app with a mobile-optimised web layer for guests and Instant split participants.

  • iOS app with full account features
  • Public web links for guest claiming — no account required
  • Multi-currency groups with automatic historical exchange rates
  • German and English, auto-detect with manual switch

Building a product from the ground up?

Whether you have a product idea like Quitty or need a team to take an existing concept through design and delivery — we bring the same end-to-end approach to every engagement.
