Built from a specific frustration.
Performance teams have extraordinary data on what converts. They have almost no data on why the voice in their ads is working or failing. AdZhi exists to close that gap.
The audio signal has never been measured
A senior media buyer watches a new cut. The hook is strong, the concept solid, the product looks great. They approve it. It goes live. It underperforms. The platform shows CTR and ROAS: outcome data. It shows nothing about the drivers in the creative.
The things that separate a high-performing ad from a low-performing one are often completely invisible to the people reviewing it, however skilled, because the instruments to measure them didn't exist.
The insight is acoustic. The signals your audience's subconscious processes in the first moments (pitch, energy, credibility, delivery pattern) shape whether they swipe or stay. They've never been measured at scale for ad creative.
Measuring the creative is only half of it. The deeper conviction is the loop: forecast from those signals, run the ad, pull the real outcome back in, grade the forecast against it, and let the system learn which signals actually predict performance in your account. That feedback loop between creative and paid media is the part nobody had closed. An agent now rides it — proposing the next move on every ad, acting only within the scopes you delegate, and explaining each decision by email. It never moves your spend on its own.

Four forces converging
- 01
Creative quality is now your only real edge
iOS privacy, GDPR and cookie deprecation eroded third-party targeting precision. The ad that wins without a data advantage is the one with better creative. Increasingly, it’s the signal that decides the auction.
- 02
AI content makes authentic delivery more valuable
When every brand can generate AI ads, a real human voice delivered with conviction stands out. Acoustic credibility is becoming a competitive signal in its own right.
- 03
The analysis infrastructure became capable
Transcription accuracy, signal processing and AI reasoning reached the threshold to do this precisely enough to give a buyer a specific, actionable brief.
- 04
UGC volume has exploded
Many DTC brands now produce dozens of creator ads a month. Reviewing them systematically by hand is impossible. Acoustic analysis keeps up where human listening can’t.
What we hold to be true
The voice carries more persuasion weight than motion or colour
The visual gets the attention. But how the words are delivered carries the persuasive load: pitch authority, vocal warmth, energy at the ask. Your audience hears it before they consciously process it.
Pre-production is where the leverage is
Post-production reporting tells you what happened. Pre-production analysis gives you a chance to change it: 20 minutes to re-record instead of £20,000 to re-shoot.
Specific beats generic
“Improve your CTA” is advice. “Re-record from 0:24: your CTA was 68% of average energy. Stand up. Mean it. Target 85+” is a brief. Every AdZhi output is a brief, not a score.
The data should be honest about what it knows
Predictions start from peer-reviewed acoustic and linguistic research. As brands connect real performance data, those signals get validated against actual ROAS and CTR, and until they are, we say so. We don’t call a pattern a proof.
Ad + 知: to know, from the source
Ad: what we analyse. Zhī (知): the Mandarin character for “to know”, “to be aware of”. The name carries the founding biography: time spent studying in China, then years as a data analyst across social publishing, influencer marketing and DTC performance — watching dashboards measure reach, engagement and conversion while the creative quality that caused them went unmeasured. AdZhi is that instrument, built in London.

“I kept approving ads that sounded fine and then watching them underperform, and the platforms could never tell me why. AdZhi is the instrument I wished someone had handed me.”
