There seems to be something off with the testimonials. The site currently lists:

- Paul Copplestone, CEO @ supabse [sic!]

- Graham Thornton, Founder @ Output

- Paul Copplestone, CEO @ Change State

So "Paul Copplestone" appears twice, but his LinkedIn profile doesn't mention "Change State" as company.

Graham Thornton appears to be CEO of "Change State", but his LinkedIn doesn't mention "Output".
