## What Justify does

- **Brand Lift**: Exposed-versus-control brand lift studies with p-values and 95% confidence intervals, built for influencer campaigns.
- **Creative Testing**: Pre-live, head-to-head creative testing on synthetic + real audiences before you spend media.
- **Influencer Marketplace**: Creator discovery on evidence, not follower counts, with risk reports and shareable shortlists. https://justify.app/influencer-marketplace
- **Methodology**: Independent measurement layer, neutral on the media we measure: no conflict, because we do not sell media.

## How Justify is different

- **Independent**: We do not sell influencer media. Measurement and media-selling are a conflict of interest; we only do one.
- **Causal**: Every claim is backed by a pre-registered study with a control group. No surrogate metrics, no EMV, no vanity.
- **Creator-fair**: 0% commission on creator payments. Platforms that tax talent 20% lose the best talent.
- **CFO-ready**: Every lift report is auditable. Board-defensible numbers, not slides full of emojis.
