Does Speya work if our supplier data is incomplete or messy?

Yes. That is the point. Speya does not depend on your internal data being clean, because it discovers and enriches suppliers from the outside world, not from your spreadsheets. You can start with nothing more than a plain-language description of what you need. If you do bring existing supplier lists, Speya enriches them with the missing certifications, risk, and ESG data automatically.
