For Creators
Marketplaces like Collabstr solved discovery — a brand can browse hundreds of creators in an afternoon. But they created a new problem for you: you're one card in that browse, and the card format flattens everyone into a photo, a price, and a promise. Getting hired more often isn't about a better photo. It's about being the one listing that reads as measured.
Fast, skeptical, and in bulk. They filter by niche and budget, open a dozen profiles in tabs, skim a video or two for a few seconds each, and shortlist by feel. Nothing in that flow verifies whether your content performs — so the shortlist skews toward whoever looks most professional or costs least. The frustrating part: a brand can't choose the best-performing creator even if they want to, because no profile gives them performance to compare. That gap is your opening.
Here's what most marketplace creators don't know: some brands now vet marketplace creators by running their recent videos through attention-scoring models before hiring — especially for deals where paid budget will sit behind your content. The vetting is happening whether you participate or not. The move is to get ahead of it: score your own work first, put the numbers on your profile, and walk into the evaluation having already passed it. It's the difference between being tested and arriving with test results.
Run your three strongest portfolio videos through PreTestAds. Each gets a predicted-attention percentile against 76 top-performing TikTok ads — scored by a neural model trained on brain-response data — plus a second-by-second attention curve. Then write the result where browsing brands will see it: one line in your bio, repeated in your package descriptions, with the curve images in your portfolio. Keep the claim precise — top-quartile predicted attention, benchmarked against proven ads — and never inflate it into a sales promise. In a grid where every card says "engaging," the card with a percentile reads like the only adult in the room.
When a brand messages you, they're usually messaging three or four creators at once. Most reply with availability and rates. Reply with evidence: a relevant sample with its score, and — for bigger deals — an offer to score the actual deliverable before final handoff. That second part quietly solves the brand's real anxiety on whitelisting and Spark Ads deals: they're about to put media spend behind your cut, and you're the only candidate offering to prove it holds attention before they commit. Your rate conversation inherits the same evidence.
Marketplace algorithms and brand behavior reward the same thing: completed orders that went well. Scoring your deliverable before you submit it — and re-cutting the opening if the curve sags early — means fewer revisions, better reviews, and rebookings, which lifts your placement in the browse, which brings more inquiries you can answer with evidence. The flywheel starts with the first scored video. Off-platform, the same numbers power your media kit, so the work isn't marketplace-specific — it's your proof layer everywhere you sell.

Score Your VideosUsually not because your content is bad — because your profile gives a browsing brand no way to conclude it's good. Marketplace profiles mostly show the same elements: photos, follower counts, package prices, and self-descriptions. When every listing makes the same unverifiable promise, brands pick on price, aesthetics, or follower count. Adding independent evidence — attention scores on your portfolio videos — gives them a different reason to pick you.
Beyond the basics (niche, formats, clear packages), add the one thing competing profiles don't have: a measured claim about your content. Score your best videos with an attention-prediction model and write it into your bio and package descriptions — 'my recent UGC ads score in the top quartile for predicted attention against a benchmark of 76 top-performing TikTok ads.' Specific and checkable beats enthusiastic and vague.
Increasingly, yes — and not just follower stats. Brands know engagement rates come from your warm audience, so some now screen candidates' actual videos through attention-scoring tools before hiring, especially for whitelisting and Spark Ads deals where their media budget rides on your content. Showing up with your own scores means you've pre-passed the check.
