Cardless, a credit card platform, has secured $60 million in a Series C funding round led by Spark Capital, with participation from Coinbase and Bilt. This latest investment brings Cardless's total funding to over $170 million. The company, which enables brands to create and manage branded credit cards through APIs, aims to revolutionize the $200 billion credit card industry by reducing launch times from 18 months to just 90 days. Cardless's partners include notable names such as Bilt, Coinbase, Qatar Airways, and Alibaba, with co-branded card programs experiencing a 400% increase in transaction growth year-over-year. The new funds will be used to expand existing programs, introduce new co-branded cards, and develop customized financial products.
