Most creator selection still starts with a follower count and a gut feeling. Both are real signals — and both are weak. Followers say nothing about audience overlap with your market, and gut feel doesn't scale past the tenth campaign.
The signals that matter
Every creator on Supapost carries a verified performance record built from connected platform accounts and past campaign outcomes. When you write a brief, the Creator Agent scores fit across four groups of signals:
- Audience: geography, language, demographics, and overlap with the campaign's target market.
- Engagement quality: verified engagement rates with bot and invalid-traffic filtering applied first.
- Content style: formats, pacing, and topics — matched against what the brief actually needs.
- Track record: how this creator performed on similar briefs, budgets, and platforms before.
From score to forecast
Fit is a ranking; the more useful number is the forecast. For shortlisted creators, Supapost predicts expected engagement and reach ranges for this specific brief, so budget conversations start from an estimate instead of a hope. Predictions are compared against actuals after every campaign — which is how the model earns the right to be trusted.
The shortlist isn't who is biggest. It's who is most likely to move your number.
Humans stay in the loop
The agent proposes; you dispose. Every invitation is approved by the brand, negotiated rates stay private, and creators see why they matched — which keeps the system honest on both sides of the marketplace.
