Yes — it is compiled independently by our AI from dated, public evidence: business registries (via grok), an automated website audit, and Dorrenhaus's own site — not from anything the company submitted. Where Dorrenhaus states something about itself, we show it beside the public record, so you are reading sourced facts, not marketing.
