Creator marketplaces charge per video. Billo is about $99 per creator video, and Trend about $69 to $92 per creator video. Insense runs on a subscription from about $500 per month, and JoinBrands charges a subscription plus a fee per creator. Check their sites for current pricing.
With UgcVids the price is per month, not per video. Starter gives you 20 ads a month for $24 a month on yearly billing, and Growth gives you 60 ads a month for $55 a month on yearly billing. There is no shipping product to anyone and no waiting on someone else's schedule, because the ad renders in a few minutes.
A human creator brings a real personal story, and some brands want that. When you need many hook variants to test in paid social, an AI UGC video generator gets you there faster and for far less per ad.
