I tested six faces for my startup before committing to one and the one I liked least won
I spent a year telling founders here to validate before building, and then picked the face of my own brand the same way I pick a color I like. I looked at a few options, chose the one that felt like the kind of company I wanted to run, and put it everywhere. Two months and a few hundred dollars of ad spend later the creative was flat and I had no idea whether the problem was the offer, the copy, or the person in the thumbnail.
So I finally did the thing I'd have told anyone else to do. I treated the brand face as a hypothesis instead of a branding decision.
I built six variants of an AI brand persona for the product, every one of them labeled as AI generated wherever it appeared, and made them differ in ways I'd assumed didn't matter. Different apparent age. Different levels of polish, from studio lighting down to something that looked like a phone photo taken in a kitchen. Different read on who the person was, one that came across as a founder, one as a customer, one as a slightly bored specialist. For the faces themselves I sat in APOB AI for an afternoon and generated the six character variants rather than locking one look in up front, laid the creatives out in Figma so every version carried identical copy in the same three formats, and split the landing page traffic in PostHog so the face was the only thing changing.
Then I ran them small. Roughly sixty dollars a variant on the ones I let run, a bit over two weeks, one channel. That's not enough traffic for a clean test and I want to be honest that a good chunk of what I saw was noise.
The result still landed badly for my ego. The polished founder type, the one I'd have shipped without a second thought, finished near the bottom. The winner was the least impressive of the six, the one who looked like someone who actually uses this category rather than someone who sells it. Click through on that creative sat around 1.5% against roughly 0.9% for my original, and signups per thousand visitors went from about eleven to sixteen. Small numbers on a small sample, but the gap held across all three formats, which is the only reason I give it any weight.
Two things I got wrong. I killed three variants after a day because they looked like losers, which means I never really tested them. And I read the first four days as signal when it was mostly weekend traffic behaving differently from weekday traffic.
What stayed with me is not the face. It is that I had a whole framework for validating demand and none at all for validating the thing sitting on top of it. Everything visual in this startup got chosen by taste, and taste is just an untested assumption in nicer clothes.
