No testimonials yet — on purpose

Scroll this site and you’ll notice something missing. No logo wall. No “trusted by 10,000 teams.” No smiling headshot saying the product changed their life. The reason is simple and a little unusual to say out loud: we don’t have external customers to quote yet, so there is nothing honest to put there. Rather than manufacture the appearance of social proof, we left the wall empty and wrote this essay about why.

Social proof is the easiest proof to fake

Testimonials are unverifiable by design. You cannot check whether the quote is real, whether it was written by marketing, whether the person still holds the view, or whether nine unhappy users exist for each happy one quoted. A logo wall is weaker still — it often means someone at that company once signed up for a trial. None of this is checkable, which means — as with every unverifiable claim in AI — the good actors and the bad actors produce identical-looking evidence. When both kinds of vendor have an identical wall, the wall carries no information.

What we show instead

Proof you can check without believing us. The AI Trust Index scores 18 frontier models across 13,171 scored pairs against ground truth — out-of-sample Brier of 0.1877 versus a 0.25 uninformed baseline — with the errors published and the methodology hashed so it can’t quietly change. The record is recomputable: arithmetic, not anecdote. And the tools themselves are open to inspection the only way that matters — ten of them are live and free to try, no account required. We’d rather you form your own opinion in five minutes than borrow a stranger’s.

The standard to hold everyone to

Here is the useful takeaway, and it applies to every AI vendor including us. When you evaluate a product, sort its evidence into two piles: claims you could verify yourself (public scoring against ground truth, recomputable records, a product you can try before believing) and claims you are asked to take on faith (testimonials, logo walls, “industry-leading,” unnamed case studies). The second pile isn’t always false — but it is always unverifiable, and a vendor who leans on it heavily is telling you which kind of evidence they’d rather you not ask for. The ratio between the piles is itself a signal.

When testimonials do arrive

Someday this site will quote real users — and when it does, the quotes will sit on top of the checkable evidence, not in place of it. That’s the ordering we think the whole industry owes you: measurement first, opinion second. A company built on calibrated truth doesn’t get to bootstrap itself with the one genre of marketing that can’t be calibrated. Until the real thing exists, the wall stays empty, and the index, the free tools, and the recomputable record will have to make the case on their own. We think that’s a feature.
