Practical questions

FAQ

How often does Factbase review this ranking?

We revisit category pages when material public information changes and date each report so readers can judge its freshness.

Can a company pay for a ranking position?

No. Commercial relationships do not determine editorial order. Any future sponsored placement would be labeled clearly.

Should I contact more than one company?

Yes. A short discovery conversation with two or three relevant teams is usually the clearest way to compare working style, scope and cost.
