Our take

Founded in 2022, Klink Finance is a cryptocurrency asset management platform that operates at the point of intersection between gamified consumer finance and blockchain technology.

The company was inspired by - and hopefully will follow in the footsteps of - the UK Government’s Premium Prize Bonds. Klink’s model which deploys gamification in the personal finance landscape is an interesting reimagining of the industry and could therefore have a unique impact on user engagement.

Seed funding, led by Blockchain Founders Fund as well as BlockBase, will be used to carry out its product development phase to ultimately launch the product.
