Influencer marketing agency
An influencer marketing agency built for campaigns at scale
Sup does the work of a full service influencer marketing agency for brands and agencies that run creators by the hundred.

Creators by the hundred
A search that does not run out
An agency’s roster is the creators it already knows, and a big campaign empties it fast. We search Instagram and TikTok live, across 350 million creators, for each brief. So a campaign can grow city by city and niche by niche without reusing the same faces.
- Any niche, any size, in the countries you sell in
- Fees agreed against your cost per 1,000 views target
- You approve every creator before they are booked
The paperwork
Every contract, tax form and payout handled
At volume the hard part is not finding creators. It is the contracts, the tax forms and the payouts for each one. Every creator signs an agreement written from the deal, gives their tax details on a secure page, and is paid by bank transfer once their approved post is live.
- One agreement per creator, signed on a phone
- Form W-9 or W-8BEN collected before payment
- You pay Sup once. We pay every creator
Tracking and ads
Every post tracked, and ready to run as an ad
Each live post is found and read three times a day, so the report shows what every creator delivered. Paid usage is in every agreement, so the posts that work can run as Spark Ads or partnership ads straight away.
- Views, likes, comments, shares and saves on every post
- Creator cost per 1,000 views for the whole campaign
- Ad codes collected in the platform

What it takes
What a large creator programme needs
A campaign with a few creators can run on email. One with hundreds cannot. These are the jobs that grow with every creator you add, and how each one is done.
| The job | Why it gets hard at volume | How Sup does it |
|---|---|---|
| Finding creators | A roster runs out, and the same faces repeat | A live search across 350 million creators for each brief |
| Agreeing fees | Every creator negotiates on their own | Fees agreed inside the budget against your target, then approved by you |
| Contracts | One document per creator, each with its own terms | Written from the deal and signed on a phone |
| Tax forms | Every creator needs one before they are paid | Form W-9 or W-8BEN given on a secure page |
| Ad labels | Each creator labels posts their own way | In the brief, then checked on the draft and the live post |
| Payouts | Hundreds of invoices and transfers | One invoice from Sup. We pay every creator |
| Reporting | Posts are spread across hundreds of accounts | Every post read three times a day into one report |

FAQ
Influencer marketing agency questions
What does a full service influencer marketing agency do?
It plans and runs a brand’s work with creators from start to finish. It finds the creators, agrees each fee, writes each contract, briefs the creators, checks the drafts, pays the creators and reports the results. Sup does every one of those jobs, for brands and for agencies.
How do brands run creator programmes at scale?
They stop handling creators one by one. A large programme needs a search that can find hundreds of the right creators, fees agreed against a target, one contract per creator, every draft checked, every creator paid and every post tracked. Sup runs all of that in one place: we search 350 million creators live for the brief, and you approve each creator and each post.
Our agency is too slow to scale our creator programme. What are our options?
Three, broadly: hire more people in house, buy software and run it yourself, or hand the work to a team built for volume. Sup is the third. A shortlist comes back within 6 hours of a brief, and our team and our AI agents do the contracts, the checks, the payouts and the tracking. Agencies use Sup too, and keep their client.
How much does an influencer marketing agency cost?
Most agencies charge a monthly retainer, a share of the campaign budget, or both, and few publish either. Sup has no monthly fee. You pay the price you approve for each creator, when their post is live, and we take our fee from creators. A gifting-only campaign pays $19 per gift as our fee.
How many creators can one campaign have?
The search is live, not a fixed roster, so the brief and the budget set the number. Campaigns start at about 10 creators. Our gifting programme for Moco Museum had more than 300 creators posting across London, Amsterdam and Barcelona.
Can we run the creators’ posts as paid ads?
Yes. Paid usage is written into each creator’s agreement as a length of time, so the best posts can run as Spark Ads on TikTok or partnership ads on Meta without a second negotiation. We collect the ad codes in the platform.
How is a large campaign measured?
Post by post. Every post’s views, likes, comments, shares and saves are read from the public post three times a day and listed in one report, with the creator cost per 1,000 views. Across our paid campaigns that cost has been $10.10. A view count includes views from ads run on the post. Sales are counted only where a code or a link can count them.
Do you work with brands outside the US and the UK?
Yes. We work with brands and agencies in any country, and pay creators by bank transfer in dollars, pounds or euros.
