Trust is not a feature. It is a sequence.
A progressive matching service that helps couples build confidence before meeting compatible travelers at an Airbnb Experience — designed, prototyped and tested as a final-report deliverable for the University of Toronto Service Design program.
Couples want memorable social experiences, but meeting strangers raises uncertainty — safety, compatibility, expectations. More information does not fix that; confidence has to be built gradually.
Solo service designer and concept researcher: ideation, concept prioritization, prototyping, testing with three participant groups, and the revision that followed.
Two concepts were developed — an Interest Quiz and Travel Together. I chose Travel Together: harder to deliver, but more distinctive and far better suited to testing trust.
Three participant groups with different travel mindsets — social explorers, family planners and cautious users — disagreed on plenty, but converged on the same trust requirements.
Stated plainly: a tested concept, not a launched service. The evidence is what three groups consistently required before trusting — not adoption or business impact.
Travelers may want memorable social experiences, but meeting strangers creates uncertainty about safety, compatibility and expectations. The design problem is confidence, not discovery — and trust has to be built gradually while participation stays optional.
Two directions were developed further: a personalized Interest Quiz — easier to implement, useful for discovery — and Travel Together. I selected Travel Together: harder to deliver, but more distinctive and better suited to testing trust.
The prototype broke the decision into five steps. Each screen tested a different adoption barrier instead of asking users to commit immediately.
Choose whether to participate.
See that a compatible couple was found.
Understand why the match fits.
Build confidence before meeting.
Retain control over the final decision.
Social explorers, family planners and cautious users had different concerns — family travelers wanted information about children and travel pace, younger couples expected familiar social interactions — but all three groups agreed on the foundations: explain the match, verify profiles and reviews, chat first.
Before: compatibility score, direct invitation, basic profile, immediate meeting. After: explainable match, optional opt-in, verified profile, guided chat and safety controls. The concept shifted from introducing strangers to supporting a progressive trust journey. Recommendation: pilot it in naturally social formats — food tours, walking tours and workshops.
"Make this experience more social" — yes, maybe later, or no thanks.
94% match — with its reasons listed: pace, food, group size, languages, verified IDs.
Verified profile, 18 reviews, shared interests — and the right to decline politely.
Chat before meeting, with suggested icebreakers that lower the social risk.
"You're ready" — meeting point, experience details and safety options, confirmed.
The five-step progressive trust journey. Each screen of the prototype was designed to test one adoption barrier — opt-in, compatibility, credibility, conversation, control — and testing with three groups turned the sequence into the revised concept.
