How it works

Where UGC deals get started.

grubstake.gg is the meeting place for Fortnite UEFN creators, investors, and builders. Post a listing, find the right people, and make something worth playing.

Three listing types

Post what you need. Find what you want.

💰 Fund my project

Seeking investment

A creator posts their island concept and offers a revenue share percentage in exchange for funding. Investors browse, reach out, and negotiate terms directly with the creator.

Example: "Building a Fortnite UEFN island. Offering 15% of revenue for 2 years or a 5x return — whichever comes first. Looking for $5,000."
🛠️ Find talent

Seeking collaborators

A creator posts an open role — builder, artist, coder, sound designer — and offers revenue share in lieu of upfront pay. Interested talent reaches out directly through the listing.

Example: "Need a UI designer for a Fortnite UEFN map. Offering 10% rev share for the first year. Remote, async-friendly."
🔍 Find a project

Seeking opportunity

Builders or investors post what they bring to the table and let creators come to them. A good option if you have skills or capital and would rather be found than go browsing.

Example: "Experienced UEFN builder, 3 shipped maps. Open to rev share on the right project. DM me."

Revenue share structures

Common deal structures.

These are the most common structures you'll see on grubstake.gg. Each has different tradeoffs — pick what fits the project.

⏱ Time-bound

Revenue share expires after a set window — for example, 90 days post-launch. A clear end date for both sides.

🎯 Return-cap

The arrangement closes once the investor has received a defined multiple back — for example, 5x. The creator knows exactly when they're free and clear.

⭐ Combined

A return-cap with a time limit fallback — "5x or 3 years, whichever comes first." Gives both parties a defined exit.

A note on agreements: Whatever structure you choose, put it in writing before any money changes hands. A short, plain-English agreement protects both sides and keeps the deal on track.
