Not another review site
Consumer review sites weren't built for how businesses choose each other. Insiderz is.
Generic review sites
- Built for consumers, not B2B
- Anyone can post — hard to trust
- No company verification
- Endless filters to wade through
- No secure way to message other businesses
Insiderz
- Built for SME-to-SME, not consumers
- Reviews tied to a real order or PO
- Every business verified via Companies House
- AI search in plain English (in beta)
- Secure messaging on the way
What a review looks like
“Responsive, professional and delivered exactly what we agreed. We've since moved all our IT support to them — would recommend to any small business.”
