How it works

Three steps.
Real stakes.

We evaluate on execution quality, not resume keywords. Every contest ships with a rubric — and every judge uses it.

Pick a live brief

Choose from open bounty briefs. Each includes Figma files, functional requirements, and a data API.

Build & document

Build the product. Record a Loom walkthrough and submit your source code. Every decision counts.

Win money. Get hired.

Get scored on our transparent rubric. Winners get paid $50 bounty instantly.

Why 8x

Start shipping, not applying

The traditional path rewards keywords and trivia. We reward what you can actually build.

The old way

  • Resume black hole
  • Ghosted after take-homes
  • Whiteboard trivia tests
  • Generic portfolio pieces
  • Zero feedback loop

The 8x way

  • Real-world product briefs
  • Polished, usable apps
  • Transparent scoring rubrics
  • Cash bounties in days
  • Direct hiring signals

What you submit

Four things,
then you ship

Missing demo clarity is one of the fastest ways to lose points. Record the Loom before you write your reflection.

01

Source code

A link to your public GitHub repo. We audit for quality and structure.

02

Loom walkthrough

A 2-3 minute video explaining your decisions and showing the app in motion.

03

AI logs

Show us how you used AI to accelerate. We value prompt engineering skills.

04

Resume/CV

Optional. Top builders get their profiles highlighted to hiring partners.

Questions

Frequently asked

Anyone. Whether you are a student, self-taught, or a senior engineer, contests are judged purely on the work you ship — not your background or resume.

Every submission is graded by senior engineers against a standardized weighted rubric: product fidelity (40%), engineering quality (35%), and communication (25%).

A link to your public GitHub repo, a 2-3 minute Loom walkthrough, your AI usage logs, and optionally your resume/CV.

Prizes are paid out within days of winners being announced, via PayPal, Wise, or bank transfer — whichever you prefer.

Yes. Top finalists get their profiles highlighted to our hiring partners, and standout builders are invited to production teams at 8x Social.
