## Summary

Across more than 3,800 creator candidates assessed for Adidas, ESN, and REWE, median purchase lift is remarkably stable from nano to mega tier — contradicting the widespread belief that smaller creators reliably out-convert their larger counterparts at the point of sale.

## The nano-advantage narrative doesn't survive the full distribution

The industry consensus in 2025–2026 strongly favours nano and micro creators, pointing to engagement rates of 4–8% versus under 1% for mega accounts. But engagement and actual purchase conversion are different signals. When demographics-adjusted purchase lift is measured across the entire candidate pool — not cherry-picked examples — the tier gap shrinks to noise. For Adidas (nano–mega range: 1.75×–1.95×) and ESN (2.86×–3.50×), statistical testing confirms no significant tier effect. REWE shows a statistically detectable difference, but the spread (1.80×–2.23×) is small in commercial terms. The extreme individual lifts of 6×–12× sometimes cited for small creators are right-tail outliers, not the typical result in their segment. For brands negotiating creator fees, this means follower count alone is a weak proxy for expected audience affinity — creator-to-brand fit and audience overlap quality matter more than tier.

## Chart

Grouped bar chart showing median demographics-adjusted purchase lift (y-axis) by follower tier (nano to mega, x-axis) for three brands — Adidas, ESN, and REWE — each represented by a distinct colour. Error bars indicate the 25th–75th percentile range; the number of creator candidates per bar is annotated on the chart. The observation period is June 2025 to June 2026.

## Methodology

Purchase lift was measured for all creator candidates evaluated for Adidas, ESN, and REWE using a creator–audience affinity model that identifies creators whose followers over-index on actual brand purchases. Lift figures are demographics-adjusted (age × gender) based on 12-month purchase and follow behaviour among verified brand buyers. Each creator was assigned to a follower tier (nano, micro, mid, macro, mega) using a standardised classification. The chart shows median lift and the interquartile range per tier and brand; candidate counts per cell are indicated on the chart. The observation window covers June 2025 to June 2026.
