Storyblocks picks creators with a score.
The stock-media company replaced gut-feel creator selection with a custom Trudy Score, built on two years of their own campaign data.
About half the roster wasn't working.
Storyblocks sells stock video, audio and images by subscription, and pays thousands of creators on YouTube, Instagram and TikTok every month, with hundreds of partnerships live at any one time. At that scale, selection ran on gut feel and team relationships, with no number to defend a pick in a planning review.
A 50% miss rate, applied to thousands of partnerships a year, is real money going to underperforming creators.
We built them a score from two years of their own campaigns.
Share the history
Storyblocks handed over two years of past campaign data: who they ran, and how each one performed.
Train a Trudy Score
We built a custom model on that data to predict which creators would convert for Storyblocks.
Prove it on unseen creators
We held back part of the history and tested the score on creators the model had never seen. That test is where the 1.8× comes from.
How the score reads a creator.
A Trudy Score isn't built on follower counts. For every creator, Trudy analyses more than 160 research-backed signals of genuine influence, drawn from how a creator actually communicates.
Every word they say
The vocabulary, framing and narrative patterns a creator uses to carry an audience from interest to action.
How they say it
Tone of voice, pace and emphasis. The vocal cues that separate genuine conviction from a flat read.
Their face on camera
Facial expression and on-screen presence that shape how trustworthy, warm and engaging a creator feels.
Personality & psychology
Profiles grounded in published behavioural research that proxy for trust and persuasion.
Those signals roll up into one score that tells you why a creator works.
Higher Trudy Score, higher conversion.
Across a held-out test set, creators with a high Trudy score converted at 1.8× Storyblocks' previous baseline rate.
Same creator spend. 1.8× the conversions, and the new-subscriber revenue that comes with them.
Each dot is one creator from the held-out test set. Conversion rate climbs with Trudy Score. The strongest converters, shown in green, cluster in the high-score zone, where Storyblocks now concentrates spend.
