Built on Trust and Transparency
Learn how we secure funds, handle payouts, and maintain a fair ecosystem for both sponsors and technical creators.
Escrow by Default
Every sponsorship is backed by funds held in escrow. Creators work with the certainty that they will be paid, and sponsors only release funds upon proof of work.
Instant Payouts
No more 30-day billing cycles. Once a placement is verified, the funds are instantly available in the creator's wallet for withdrawal.
15% Service Fee
One flat, transparent fee covers everything: payment processing, verification technology, and our marketplace infrastructure. No hidden costs.
How Sponsors Pay
Deposit Funds via Moonpay
Sponsors add funds to their platform wallet using Moonpay. We currently support instant **Crypto Checkout**, with **Credit Card** support arriving soon.
Lock into Escrow
When a campaign launches, the total budget (including fees) is moved from the Sponsor's wallet to a secure **Escrow Account**. This guarantees the creators will be paid.
Automatic Protection
If a creator declines a request or fails to publish within the agreed window, the funds are instantly returned to the Sponsor's wallet.
How Creators Get Paid
Accept & Publish
Creators review incoming offers. Once accepted and published, the creator submits the "Proof of Work" (the live newsletter URL) to the system.
Automated Verification
Our system verifies the placement, checks for tracking links, and confirms the content matches the approved creative. No human back-and-forth needed.
Release of Funds
Upon verification, funds are released from Escrow directly to the Creator's payout wallet. Creators can withdraw to their bank account anytime.
Simple, Flat Fees
We believe in a fair marketplace. Our 15% service fee is only finalized when you succeed.
Single Service Fee
Taken at Fulfillment
Unlike traditional agencies that charge upfront "setup fees", we only take our commission when the sponsorship is verified. This aligns our incentives perfectly with yours.
