JohnPaul Williams II, AI Sales Trainer and Builder of Rex

I've sold for years, on almost every kind of floor. Shoe stores, clothing, warehouse clubs. Then B2B: cannabis, e-commerce, and my own marketing agency.

And I still froze. Not on product knowledge. The moment the sales hat was officially mine, the part of selling I'd spent years working around became the part I had to break through. If you carry a number, you know that freeze. I've been there.

I'm a mind-over-matter guy. I knew where this was heading, and I needed a way to hit the gym on it without drilling in bad technique.

So I built Rex for me.

Not because I was good. Because my emotions were out of whack and I needed somewhere to practice without anyone watching.

I'd get on calls already convinced the answer was no. Lead with apology. Soften the ask before anyone pushed back. That's not a knowledge problem. You can't read your way out of it. The only fix is reps. Enough of them that the composed version of you starts to feel like the real one.

So I built an AI sales trainer that would give me that. Something I could run objection drills and roleplay with, alone, until the language patterns I needed started showing up on their own. Not an AI sales training course to click through. An actual place to reset the wiring and build the confidence to show up as myself on a real call.

It helped. More than I expected.

What I didn't see coming was the gap tracking. Rex logs where things break down. The specific patterns. The moments you don't know are costing you. That data changed how I practiced.

Today Rex works for solo reps and for teams, small to large. Every rep gets a dashboard with their own gap profile over time. Managers get a team dashboard that shows where each rep is getting stuck before it shows up in the numbers, plus white-glove onboarding: Rex reads your company website and drafts your objections and roleplay scenarios for you to approve. Not a gut feeling. Just the actual data, week over week.

I still run it on weekends. That's not changing. I'll be here every Saturday pushing it forward, curious where it goes and how to make it better.

If any of this sounds familiar, Rex is a place to get those reps. No audience. No judgment. Just you and the work.

I've canvassed street corners for monthly subscriptions. I've sold shoes, clothes, and thousand-dollar websites and marketing packages. I'm no guru. But I've lived this at enough levels to know the repetitions are what make the difference.

I hope it does for you what it did for me.
