The rules we hold these pages to.
- Every fact about another company links to its source; “reportedly” marks secondhand figures.
- Each page says where the other option is stronger — scale, track record, certifications, customers.
- We’re explicit that Sandworld is early-stage, with no customers or certifications yet.
- No disparagement. If a fact is out of date, tell us and we’ll fix it.
