InternSea

InternSea is a marketplace with high coordination overhead: candidates, hosts, timelines, and placement logistics all need to work smoothly to create trust.

Problem: Internship marketplaces fail when coordination breaks: unclear steps, slow follow-up, and manual tracking create drop-off on both sides of the market.

Solution: Horizon Labs focused on shipping the essential “marketplace loop,” including:

• Candidate and host onboarding flows
• Listings and discovery that reduce friction to apply/book
• Placement management workflows to keep both sides aligned
• Operational tooling to avoid everything living in spreadsheets

Outcome:

• Working marketplace MVP that supported real placements
• Reduced coordination burden on the founding team
• Clear foundation for iteration as the market validated
