Listed
The entry tier. It marks a declared presence on the platform, nothing more, and it's labeled as exactly that.
That an identified person created an account, declared a company name, a country and an activity, and signed the registration statement and the anti-trafficking charter.
The declarant's own statements, and nothing else. No document is checked against a registry at this tier.
Neither the company's legal existence, nor the reality of the activity, nor the holding of any permit, nor the quality of what's on offer.
Create an account, sign statement A1 and the charter. A person reviews the registration before it's approved, and a rejection comes with a reason.
