Case study

Problem

Sick Day Sports Club is a curated experiences marketplace. Unlike open marketplaces, the value depends on trust and quality control: the platform must enforce who can list, what they can offer, and how visibility works. Otherwise quality degrades and operations become manual.

They needed to launch quickly while maintaining a “curated” experience:

Trust requirement: hosts must be certified/approved before being promoted
Tiered offering model: different host tiers needed different visibility and pricing rules
Booking edge cases: minimum group sizes, “free” experiences, and controlled inventory needed to work reliably
Admin overhead risk: without built-in tooling, the team would become the gatekeeper for every exception

Solution

Horizon Labs implemented a Sharetribe marketplace foundation and built a certification + tiering layer:

Certification workflow with admin review, approval, and badges
Tier-based visibility controls so only approved/certified hosts appear in the right contexts
Flexible listing model supporting free vs paid offerings
Guest count range logic and minimum group-size handling
Admin interface to manage approvals and enforce policies without engineering involvement

Outcome

Launched a curated marketplace model with trust built into the product
Reduced operational load by making certification and tiering first-class workflows
Enabled marketplace scaling without sacrificing quality control
Created a foundation for continued supply onboarding and monetization experiments
