Quick answer
Which platform fits your campaign?
Upfluence, GRIN, Aspire, Collabstr, Modash and HypeAuditor are influencer marketing platforms: they find creators, run campaigns and pay flat fees. Referly is affiliate software. Creators get a link and a coupon code and earn a commission per sale. Choose by payment model first, database size second.
GRIN
Continuous creator programs with seeding, approvals and content rights.
Modash
Discovery and vetting, with prices you can actually read.
HypeAuditor
Fake-audience detection is your biggest risk.
Collabstr
One-off bookings at a fixed price, like buying a product.
Upfluence
You want creators matched against your own customer list.
Referly
You would rather pay a commission on sales than a fee per post.
The decision
Two different products, one search term
Influencer platforms find creators and pay them to post. Affiliate software pays creators when their audience buys. Most brands run both.
| Influencer platform | Affiliate software | |
|---|---|---|
| What you pay for | A post, agreed up front | A sale, after it happens |
| Who carries the risk | You | The creator |
| The numbers you see | Followers and engagement | Revenue and conversion rate |
| Typical database | Millions of scraped profiles | Creators already selling |
| Best for | Awareness and launches | Performance and repeat revenue |

The shortlist
Seven platforms, honestly compared
Three publish no price at all. We say so instead of guessing, and ours is last because it is a different category.
GRIN
The deepest end-to-end creator workflow: sourcing, gifting, contracts, content rights.
- Publishes a real price ladder, free tier included
- Credit-based metering with a spend cap you set
- Month to month, no sales call required
Limitation: Credits are burned by automated work, so the bill moves with activity and is hard to forecast. The hands-on workspace starts on the $500 tier.
Best for brands running always-on creator programs.
Modash
Discovery and monitoring over 380M+ profiles, with published prices.
- Huge index across Instagram, TikTok and YouTube
- Plain published pricing, rare in this category
- Payments with 0% fee up to $10k/yr on Performance
Limitation: Meters on opened profiles and unlocked emails, so research-heavy months cost more whether or not anything ships. No payments on the $199 tier.
Best for teams whose bottleneck is finding and vetting creators.
HypeAuditor
Analytics-first discovery with the best fraud detection in the space.
- 227M+ profiles with 35+ filters
- Audience authenticity scoring is the core product
- Around forty genuinely useful free tools
Limitation: No price is published anywhere. The buttons say Request demo. Commission logic and payouts are not the product.
Best for teams whose main risk is fake audiences.
Collabstr
A fixed-price marketplace. Browse, book, escrow, delivered.
- The fastest way to get one piece of creator content
- Escrow protects both sides
- No annual commitment
Limitation: You get a transaction, not a relationship. We could not verify current pricing on their own site, so this page states none.
Best for one-off bookings and first tests.
Upfluence
Discovery plus ecommerce, with one unique trick: creators matched to your customers.
- Finds the creators already buying from you
- Shopify and WooCommerce integration
- Discovery through campaign management in one
Limitation: No pricing published anywhere, sales-led, annual contracts. Not a tool you trial on a small budget.
Best for ecommerce brands with a customer base worth mining.
Aspire
Campaign management and creator relationships at scale, strongest in fashion and beauty.
- Built for long-running relationships
- Deep reference base in fashion, beauty and CPG
- End-to-end campaign workflow
Limitation: Three plans, no prices published on any of them, no free plan and no trial. Every evaluation starts with a sales call.
Best for larger teams with a signed-off budget.
Affiliate software. Creators get a link and their own code, and earn per sale.
- Discovery profiles carry real revenue and conversion history, not follower counts
- Signing bonuses paid automatically on acceptance
- Payouts, tax forms and a branded portal included
Limitation: Not an influencer marketing platform: no content approvals, no seeding, no media planning. Influencer Discovery is a $199/mo add-on with 500 invites a month, on top of a $75/mo plan, and the database is Referly's own network, far smaller than a scraped index.
Best for brands that want to pay on results.
Before you pick
Six questions that decide it
Flat fee or commission?
Decide this first. It halves the list before you compare a single feature.
Whose numbers are these?
Follower counts measure reach. Earnings history measures sales.
Who keeps the relationship?
Marketplaces optimise the booking. Programs optimise month twenty.
How do creators get paid?
PayPal, Wise or bank, and someone has to collect the W-8.
Can one creator do both?
Fee for the launch, commission on the tail. The normal end state.
Can you read the price?
Only two platforms on this page publish one. That is a signal.
Run the numbers
Flat fee or commission, on one post
Below a certain conversion rate the flat fee genuinely wins. See where that line sits for your numbers.
- Flat fee
- $1,200
- $7.50 per customer
- Commission at 20%
- $2,176
- $13.60 per customer
At this conversion rate the post drives 160 customers and $10,880 in revenue, so the flat fee is cheaper. You paid once and kept the upside. The two models cost the same at a conversion rate of about 0.22%.
The verdict

Always-on creator campaigns with a team

Influencer marketing pays a creator to publish, fee agreed up front, and you carry the conversion risk. Affiliate marketing pays a commission when their audience buys, so the creator carries it. Most brands eventually run both.
