Which Dragon's Den investor is known for the retail stationery chain Ryman?

Theo Paphitis is known for owning and developing the Ryman stationery retail chain.

Paphitis became associated with Ryman after acquiring the business in the 1990s. Under his ownership, the chain expanded its presence in British high streets and became one of the best-known names in stationery and office supplies.

He joined Dragon's Den as an investor in the programme's early years. His expertise was especially linked to retail, branding, purchasing and the operation of chains with physical stores.

Paphitis has owned or backed several other consumer businesses, so Ryman is not his only commercial association. The company is nevertheless the clearest answer to this question because it is the retail brand most directly identified with his public business profile.
