SIGRIX MARKETPLACE

Meet our founding sellers.

Sigrix was built with these people. They were the first to submit. The first to get verified. The first to trust that a curated, human-reviewed prompt marketplace was worth building. Everything that came after is built on what they started.

Sigrix is the first place I've published prompts where the quality bar actually means something to buyers.

I have been creating prompts professionally for two years. Finally a platform that treats that as a craft worth recognising.

  • You can write a clear description of what your work does and who it's for
  • You can commit to publishing your first listing within 14 days of launch

FAQ

What founding sellers ask

Why only 15?
Curation only works when the bar is real. Fifteen people we can personally onboard, support, and help succeed at launch — versus a flood of unvetted accounts. It's deliberate.
What does "founding" actually mean long-term?
Your founding badge is permanent. The 15% commission is locked for the life of your account. Featured placement runs through launch month and the first major marketing push.
Can I sell prompts, personas, and agents?
Yes — all three. Your founding status applies to your shop, not individual listings, so anything you publish under your account benefits.
Do I need an audience already?
No. We weight craft over follower count. A working portfolio of real prompts buyers would pay for is enough.
What happens after the 15 are filled?
Standard sellers can apply through the normal verification flow at 20% commission. Founding seats don't reopen.
Is there an exclusivity clause?
None. You can keep selling on other platforms. We just ask that your storefront on Sigrix gets your A-tier work.
