Social Cat wins on unit economics at every published tier, which is the opposite of what pay-per-post pricing feels like it should do. Divided out per collaboration, Social Cat costs between $9.97 and $19.80. Stack Influence charges a flat $30 per completed post. Stack Influence only wins at low or unpredictable volume.
The price table

Verified 2026-08-19. Per-collab figures are the published monthly price divided by the published allotment: $99/5, $199/15, $299/30.
The arithmetic, in full
| Social Cat tier | Monthly | Collabs included | Cost per collab | Stack Influence for the same volume |
|---|---|---|---|---|
| Essentials | $99 | 5 | $19.80 | $150 |
| Performance | $199 | 15 | $13.27 | $450 |
| Pro | $299 | 30 | $9.97 | $900 |
At five collaborations a month, Social Cat costs $99 and Stack Influence costs about $150. At thirty, Social Cat costs $299 and Stack Influence costs about $900, three times as much.
The gap widens as you scale, because that is what a fixed subscription against a flat per-unit fee does. Pay-per-post feels cheaper because $0 a month sounds like nothing, and $30 sounds small next to the $649 tiers charged elsewhere in this category. Against Social Cat specifically it does not hold, and I have not seen anyone put these two divisions on the same page.
There is a reason for that. Stack Influence runs this comparison on its own domain in both directions, a page framed as Stack Influence against Social Cat and a mirrored one the other way round. Both are written by Stack Influence. Neither divides Social Cat's monthly price by Social Cat's collab allotment, which is the one calculation that changes the answer.
The condition that decides it
The per-collab numbers above assume you use the whole allotment. That assumption is the entire comparison.
Social Cat's Pro tier is $9.97 a collab if you run all thirty. Run ten and you have paid $29.90 each, which is Stack Influence's price with a subscription attached. Run four and you have paid $74.75 each.
So the real question is not which pricing model is cheaper. It is whether your program produces steady, predictable volume that fills a tier every month. Mine does not always. Gifting runs in bursts around launches, and there are quiet months. A brand with that pattern is buying allotment it will not use for part of the year.
What each one is actually built for
Stack Influence is a pay-per-post marketplace. Creators complete posts, you pay per completion, and the model is aimed at micro-creator content produced in volume in exchange for product. You are buying output, and a creator who never posts costs you nothing. That last property is worth more than it looks in gifting, where non-delivery is routine rather than exceptional.
Social Cat is a matching service sold as a monthly subscription with a collab allotment. You are buying capacity, and the discipline of that model is that unused capacity is wasted money. Its 7-day trial is a real advantage at the evaluation stage, because you can find out whether creators in your category are actually on the platform before committing a cent.
The buyer split is clean. Steady monthly volume of five or more collaborations, Social Cat, and the more volume the wider its advantage. Sporadic bursts, a handful of posts, or a first program where you genuinely cannot predict volume, Stack Influence, because you only pay for what happens.
Who carries the risk when a creator ghosts you
Unit cost is only half the comparison. The other half is what happens when a send produces nothing, which in gifting is not an edge case.
I ship gifts every week for my own brand, and the number of boxes that go out is always higher than the number of posts that go up. People change their minds, lose interest, or simply never get round to it. Any gifting program has a gap between sends and results, and the two pricing models here put that gap on opposite sides of the table.
Stack Influence charges on completion, so a creator who never posts costs you nothing beyond the product. Social Cat charges monthly whether your collaborations convert or not, so a bad month is the same price as a good one. That is the strongest argument for pay-per-post and the per-collab arithmetic above does not capture it, because the arithmetic assumes every collab in your allotment turns into something.
The way to settle it is to use your completion rate rather than your intent. If you send fifteen and reliably get twelve posts, Social Cat Performance is $16.58 per post rather than $13.27, still comfortably under $30. If you send fifteen and get five posts, you have paid $39.80 each and pay-per-post wins outright. Your own completion rate decides this, not the sticker price.
Both of these SERPs are thinner than they look
One more thing a buyer should know, because it shapes what you find when you research this matchup.
Search for alternatives to either tool and the results are unusually low quality. The "social cat alternatives" results are largely the same article duplicated across several domains, including creator-hero.com, influencer-hero.com and nc-media-group.com, which is one content operation syndicating itself rather than several independent assessments. The "stack influence alternatives" results skew towards directory sites like SourceForge, Slashdot and SpotSaaS, which publish templated listings rather than considered comparisons.
The practical effect is that a buyer researching this decision keeps meeting the same source wearing different names, and almost never meets a page that divides the monthly price by the collab allotment. That is why the table at the top of this page is worth the trouble.
Who should not pick Social Cat
If your gifting is seasonal or campaign-driven, a monthly allotment is a bad fit and Stack Influence's model is straightforwardly better. Paying $299 in a month where you ran six collaborations is worse than paying $180 for six completed posts, and no amount of per-unit theory changes that.
The same applies to a brand running its first program. You do not know your volume yet, and buying a tier before you know it means guessing. Stack Influence lets you find out at exact cost. Once you have three months of data and it shows a steady floor, run the division above again and switch if the numbers say so.
What I would do
Pull your last three months of completed creator posts. Take the lowest month, not the average, because the lowest month is what your subscription has to justify. Divide the Social Cat tier that covers it by that floor number and compare to $30.
If your floor is comfortably above five posts a month, Social Cat is cheaper per unit and the trial costs nothing to confirm it. If your floor is two or three, pay per post and stop thinking about it.
Where Seed fits
Both of these tools are about finding creators and getting content made. Seed handles the part that comes after either one of them: the actual send. One branded link, the creator picks a product and variant and enters their address, and a real $0 Shopify draft order lands in your admin for approval. Whichever sourcing model you pick here, the box still has to reach a real address, and that is the job we do. Costs are on our pricing page and the app is at apps.shopify.com/influencer-form.
What Stack Influence doesn't do
- No Shopify App Store listing — runs as an off-platform managed service, not inside the Shopify admin
- No published monthly subscription tier — charges roughly $30 per completed post instead of a flat fee
- No stated minimum spend or contract length on its public pricing page
- No self-serve dashboard for the brand to run — creator sourcing, outreach, and campaign management are handled by Stack Influence's own team as part of the model, not something you're left to do yourself
What Social Cat doesn't do
- No Shopify App Store listing despite marketing directly to Shopify brands; campaigns run inside Social Cat's own dashboard and marketplace
- No free tier — entry Essentials ($99/mo) caps at 5 creator collaborations/month and 1 campaign
- Top published tier (Pro, $299/mo) still caps at 30 collaborations/month; no unlimited-orders tier is published
- Public pages don't describe how its named "Shopify" integration channel fulfills gifts — no draft-order or address-collection mechanics are documented
- No done-for-you tier — Social Cat gives you a searchable creator database; sourcing and outreach stay with your team
What Seed doesn't do
- No creator discovery database — Seed doesn't help you find creators, unlike Social Cat's 500,000+ profile marketplace
- No content guarantee — Seed ships product on approval; it doesn't buy or vet finished posts the way Stack Influence's per-post model does
- No affiliate or commission-tracking engine
- Concierge ($299/mo, 30 creators) is Seed's only done-for-you tier — outside it, sourcing and outreach on the core plans stay with your team, the opposite of Stack Influence's built-in managed team
