Doug Richard founded the online business community Library House and was an original investor on Dragons' Den.
Library House was a business-information and networking venture associated with Richard's work supporting high-growth companies. His background included technology entrepreneurship and investment, giving him a different profile from Dragons whose main reputations came from retail, leisure or property.
Richard appeared on the first British Dragons' Den panel after the programme launched in 2005. Although his time as a television investor was comparatively brief, his participation forms part of the show's original history.
The name Library House can be confused with a conventional library or with a later investment fund. In this context it refers to Richard's business community for entrepreneurs and investors, not to a public-library organization. The question also concerns the founder, rather than a company that Richard merely advised or invested in.
