Corros

Event organizer-to-venue marketplace. We rescued it after a failed devshop build: audit, rebuild plan, working platform.

Case study

Problem

Corros was modernizing a traditional event organizing business into a digital marketplace connecting event organizers with venue owners. The business value depended on translating a historically manual matchmaking process into reliable product workflows.

This was a “rescue project.” Corros had previously hired another devshop, which led to a lawsuit and a non-functional product. They were left with:

  • A broken platform that couldn’t support real users
  • Uncertainty about what could be salvaged vs. rebuilt
  • High risk of repeating the same mistakes without a clear technical plan
    They needed execution they could trust, with transparent scoping and a reliable delivery path.

Solution

Horizon Labs stabilized the effort by moving in phases:

  • Conducted a thorough audit of the existing codebase to identify failure points and root causes
  • Produced a detailed rebuild plan (approximately 700 hours) to remove ambiguity and control risk
  • Rebuilt the marketplace from scratch to create dependable organizer ↔ venue workflows
  • Established a clean technical foundation designed for future feature expansion (without compounding technical debt)

Outcome

  • Delivered a functional marketplace over the course of a year
  • Digitized and streamlined Corros’ matchmaking process (less manual coordination, more repeatable operations)
  • Created a stable platform foundation for ongoing growth and iteration

Features & Tech Stack
