Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
Collabstr
Hire UGC creators from a searchable marketplace
Collabstr is a directory of creators who will make content for a brand, with the brief, the payment and the escrow in one place. Browsing and hiring work on the free plan, which is unusual in this corner of the market. The paid tiers buy campaigns, analytics and a lower cut on each hire.
Our note
The free plan is the honest entry point here: it hires creators and holds the money, and the subscription mostly buys campaign tooling. Work out whether 5 percentage points off the fee beats $333 a month before upgrading.
Stack Influence
Micro influencer posts at a flat fee each
Stack Influence runs micro influencer campaigns as a managed service and charges per completed post rather than per month, which is the opposite of how most of this category is sold. Creators are paid in product, and the brand pays a fee when a post goes live. That makes the cost of a campaign a multiplication rather than a contract. Anybody wanting to pick each creator by hand will find the managed model frustrating.
Our note
Ask for the fee in writing before committing, since an average is not a price and this is the one number the whole model turns on. Budget for the product you are giving away as well, because that cost sits underneath the per-post fee and does not appear on the pricing page at all.
