FIG · 01— Synthetic Minds · The panel behind every Run

We built an audience
that doesn't
exist.

When you run a page, our Synthetic Minds use it the way your customers would — every button, every form, on desktop or a phone. They're built to be the people your page is for, so every finding on your Run Sheet carries the specificity, skepticism, and life experience of real customers. Back in under an hour, not weeks.

You've probably noticed that asking a chatbot to “review this as a skeptical user” produces feedback that could apply to anything. Polite, balanced, generic. It tells you to “consider adding social proof” the same way it tells everyone to consider adding social proof.

Real people don't work like that. Real people see your pricing page and feel something specific — shaped by their income, their last bad subscription experience, whether this month has been good to them or not.

A page isn't good or bad on its own. It's good or bad for someone. Our Synthetic Minds are that someone.

FIG · 02

A complete person behind every finding.

Every Synthetic Mind is a complete person. Not a demographic label. Not a “persona” on a slide deck. A person with a job they're ambivalent about, a relationship that's going well or isn't, financial stress or financial confidence, a specific history of products that earned their trust and products that burned it.

Thirteen form fields are fine for a methodical buyer at a desk. They're a dealbreaker for a parent checking out on a phone at 11pm.

Each mind has a personality, a budget, a level of patience and a history with products like yours. Those are what turn “the page could be clearer” into “this buyer won't get past the second step, and here's why.”

Same pricing page. Two Synthetic Minds. Two different pins.

MC

Maria C., 41

Doctorate, public health · Questions everything

“Annual discount? That's just a pressure tactic to lock me in before I've actually verified this works. Free trial sounds good, but how much data do they need? And ‘enterprise messaging’ — I deal with budgets; I know when someone's overselling. Show me peer-reviewed case studies, not promises. I'm not paying for anything until I see real evidence this solves my actual problem.”

Rafael W., 62

Burned by past subscriptions · Modest income

“I've been burned before by subscriptions I didn't use. Free tier is good — I'll test it. But I need to understand what ‘pro’ actually gives me that free doesn't. I'm wary of auto-renewal traps. If I'm going to pay, there better be clear documentation and honest customer support, not just slick promises.”

Pinned → Auto-renewal not explained — say how to cancel next to the price

One saw a proof problem. The other saw a trust problem. Both land on your Run Sheet, pinned to the spot, with the fix — because both are right for who they are.

Amanda S., 36

Recently lost her job · Two young kids · Watching every dollar

“Free tier is smart — I need zero commitment right now. But honestly, $29/month feels risky when I'm between jobs. The annual discount is tempting if I knew this would stick around, but what if I can't afford it in three months? I'd rather test drive it free for longer before any payment. Can I really trust this won't lock me in?”

Her reaction isn't about your product. It's about where she is in her life. A persona on a slide deck can't tell you that. She can — because we built the life behind the opinion.

NOTE— from the lab

Yes, they're synthetic. That's the point.

Real people can't go through fifty versions of a page in an afternoon. Real people can't articulate how a recent layoff changed their gut reaction to your pricing. Real people don't even know that about themselves.

Synthetic minds can — because we built the life behind the opinion.

FIG · 03

Your customers, not ours.

Start from a ready-made panel — an ecommerce shopper, a SaaS buyer, a first-time investor — or build one from your own customer data. Either way, the minds judging your page are shaped like the people who actually pay you.

And they stay in the room after the Run. Ask them why a step lost them, what they expected to see, or what would have made them buy. The Run Sheet tells you what to fix. They tell you why it mattered.

FIG · 04

Calibrated against reality.

We keep testing our Synthetic Minds against established behavioral research — the same decision-making patterns that psychologists have documented for decades. Framing effects. Decoy pricing. The psychology of free. Anchoring. Default bias.

When they don't match what real people do, we find out why and we fix it. This isn't a one-time calibration — it's a continuous process of testing the panel against documented human behavior and correcting where it drifts.

FIG · 05

Run it first.
Then test it on real traffic.

We're not claiming we've replaced A/B tests. What we've built catches the trust issues, the messaging gaps, the pricing doubts and the confusing steps that real customers would hit — before you've spent weeks building a variant and waiting for traffic to tell you it lost.

Run it to fix what's broken. A/B test to pick the winner. That's the honest workflow — and every test you launch is a fair fight between two pages that both work.

FIG · 06

The experiments you never proposed
are the ones that cost you the most.

Right now, experimentation is punished. Every experiment is so expensive — in engineering time, review cycles, and personal credibility — that PMs self-censor. Prior.Run inverts that dynamic.
