Our take
Oftentimes, the advice to those with low credit is to build it up with the careful use of high-interest credit cards. However, this comes with the obvious downside of being high risk as well as high reward. Bits, instead, helps people with low credit to improve their scores with a subscription store card that lets them access in-store savings while quickly raising their credit score.
Millions of people in the UK have difficulty accessing financial services due to their credit scores, so it is no surprise that a number of other startups like Pockit and Portify have emerged offering alternative products for this underserved group. Bits, however, stands out for its unique approach that doesn’t put people into any debt at all - with the company making no money on interest.
As Bits has grown, it has expanded its product and now reports to Equifax and TransUnion on top of Experian. Boasting 300,000 users and a strong rating on Trustpilot, it is clear the company has already made an impact and it will be interesting to see what it does in the future.
