The team that vets every listing.
Sigrix is curated by a small team that tests every AI agent, prompt, persona, skill, and assistant before it goes live — and writes the Sigrix Learn guides that help buyers choose well. We publish under the Sigrix Editorial byline so you always know who stands behind the content.
What the team does
- Vets listings. Every submission is run and reviewed against a quality checklist before it can be sold — model support, token estimates, and real example output.
- Curates the catalog. We organise listings into clear categories and surface the ones that actually work, so buyers don't sift through noise.
- Writes Sigrix Learn. The team authors the explainers and buying guides on evaluating, pricing, and building with AI agents — published as Sigrix Editorial.
- Protects digital ownership. We back every purchase with verifiable ownership records so what you buy stays yours.
