In their words
“This is the solution I'd been looking for, for over a decade. I trust it to close my stage show in front of thousands — and on live TV in front of millions.”
“Aight bro. This is just not fair. Holy Sh*t. How and when can I get this.”
“There's a hidden gem buried in this app that's become my secret weapon. It isn't even the main feature. That should tell you something about the rest.”

Questions
What we can say.
The method and effect are protected.
- Who is Sigma for?
- Working professional mentalists by invitation only. If you don't perform for money, this isn't for you — and that's not a marketing line.
- Will you describe what it does?
- Not publicly. Both the effect and method are protected. Full documentation is delivered privately to license holders after purchase. If you'd like to see it, .
- Why this approach?
- Everything published online — every ad, every video transcript, every forum post — is now permanently absorbed into AI models. Once a method or effect is described publicly, it can be summoned by anyone, forever. The value of a secret just went up. So we don't publish ours.
- How do I get an invitation?
- Existing license holders have a limited number of invites to share with vetted performers they know. Reach out to an existing user (likely the person who sent you here) for an invitation code. Additionally, we grant private demos to qualified performers.
- Refunds?
- Because access is delivered instantly and the method is disclosed, all sales are final. Contact us before purchase with any questions.
