Marketplace Rescue & Code Audits

According to our client telemetry and inbound scoping calls since 2019, approximately 25% of all marketplace inquiries are not greenfield builds—they are marketplace rescues. A founder has 300 to 500 pre-seed listings, eager early users, but zero live transactions because their prior agency or offshore freelance team disappeared, broke the Stripe Connect webhooks, or created an unmaintainable codebase.

The 3 Red Flags of a Stalled Marketplace

If your marketplace exhibits any of the following symptoms, continuing down the current development path will burn runway without unlocking revenue:

  • Stripe Connect & Payout Failure: Split payments, custom seller onboarding, or payout schedules throw silent 500 errors or fail on dispute webhooks.
  • Phantom Booking States: Calendars and listings allow double bookings because race conditions and database locks were never handled properly.
  • Unmaintainable Forks: The previous developers hardcoded business logic directly into core vendor files (e.g. Sharetribe or custom React templates) without documentation or version control hygiene, making future feature development impossible.

The 3-Step Horizon Labs Rescue Framework

We do not operate with finger-pointing. We follow an engineered protocol designed to protect your runway and get you to live, billable transactions within 14 days:

Step 1: 48-Hour Architecture & Integration Audit (Under NDA)

We sign a mutual NDA and gain read-only access to your Git repository, hosting environment, and Stripe Dashboard. Within 48 hours, an actual senior engineer (not a sales rep) inspects:

  • Stripe Connect webhook listeners, idempotency keys, and account verification flows.
  • Database indexing, query latency, and state transition integrity.
  • Third-party API dependencies, security vulnerabilities, and deployment pipelines.

Step 2: Remediation Roadmap with Hard Hour Ceilings

We provide a written diagnostic report separating "Must-Fix to Transact" from "Nice-to-Have Features". You receive an exact hour range with a hard ceiling and published hourly rates ($150/hr for senior engineering specialists, or $6,000 for dedicated 2-week sprints). We commit code directly into your repository from Day 1.

Step 3: Safe Production Cutover & 6-Month Warranty

We test payouts in sandbox and staging environments, verify edge cases across mobile web, and perform a zero-downtime cutover. Every line of code written by Horizon Labs is backed by our written warranty: if a bug emerges in work we delivered, we fix it at zero cost.

Proven Track Record in Marketplace Rescues

Horizon Labs has engineered and rescued premier marketplaces across North America:

  • RareWaters: Migrated from a crashing WordPress/WooCommerce setup to a resilient Sharetribe marketplace in under 3 months, scaling to season passes and culminating in acquisition by InfiniteOutdoorsUSA.
  • Kidsy: Built parent-to-parent resale operations on custom Sharetribe infrastructure, managing complex condition grading, local delivery, and seller payout automation.
  • SetCircle: Custom film and photography equipment peer-to-peer rental marketplace with security deposit holding and calendar scheduling.

Frequently asked questions

Can you sign our NDA before reviewing our codebase?

Yes. We routinely execute mutual NDAs prior to repository or Stripe Dashboard access. Your intellectual property and user data remain 100% confidential.

Do you develop inside our existing GitHub or GitLab repository?

Always. We do not work in walled gardens or proprietary environments. All commits land directly in your GitHub, GitLab, or Bitbucket repository under clear branch protection rules.

What if the existing codebase is completely unfixable?

We provide an honest "we're not the right fit" or explain plainly if rebuilding a focused slice on Sharetribe or a clean Next.js/Node stack is cheaper and faster than untangling bad legacy debt. You get objective engineering guidance, not a sales pitch.

How fast can we get started?

In most rescue situations, we can initiate repository review within 24 to 48 hours of brief submission.
