How it works

From brief to post.

01 · Publish

The brief

The brand posts a campaign or searches the directory: niche, audience, network, city, budget.

02 · Choose

The applications

Creators pitch their idea. kstr ranks them by relevance to your target.

03 · Pay

The payment

The brand pays through Stripe. The creator is paid once the content is approved.

04 · Approve

The content

The creator posts, the brand approves, both leave a review.

Questions

What people ask us.

How much does kstr cost?

Sign-up is free for everyone. Brands pay a service fee of 4 to 10% depending on their plan, and creators pay a 5% commission only on completed collaborations. See the Pricing page.

How does the creator get paid?

Once the brand approves the content (or automatically 7 days after delivery if there’s no reply), the amount is added to the creator’s balance, who can then request a transfer to their bank account.

What happens if there’s a disagreement?

The brand can report a problem before approving the content: the creator can first correct it, then our team helps both parties reach an agreement for 15 days. Without agreement, the brand is refunded the amount of the collaboration and waives the right to use the content.

Which social networks are supported?

Instagram, TikTok, YouTube, Twitch and LinkedIn. Creators list their statistics for each network.

Can I run kstr from my AI or my Shopify store?

Yes, for brands. The MCP connector links your account to Claude, or any compatible assistant: it reads your campaigns and giftings, prepares campaign drafts and accepts gifting applications. The Shopify connector, available on request, imports your products into your campaigns, tracks the shipping of the gifting orders you create and reads the sales made with your creators' discount codes (affiliation), read-only. No payment goes through these connections.

Will others see my brand?

Not if you don't want them to. kstr never publishes its client list, and free STEALTH mode keeps your presence confidential: campaigns without name or logo, anonymous profile visits. You reveal yourself to a creator, and to them only, when you message them or send a collaboration proposal. Learn more
