Bits helps people build credit scores through a subscription-based fintech service. The platform connects with major credit bureaus (Experian, Equifax, TransUnion) to report positive credit activity, while avoiding interest, late fees, and hard credit checks. Users pay a monthly fee to access educational resources like a score simulator and a library of videos, which teach how credit works and how to improve scores. Bits also offers a Bits Credit Card and a Bits Store Card, though these products are not regulated like typical financial products and do not come with standard consumer protections. Revenue comes from subscription fees and potential affiliate partnerships. The business differentiates itself by providing a transparent, low-risk way to build credit with a focus on education rather than traditional lending terms. The goal is to make credit-building simple and accessible, helping users raise their credit scores without high costs or hidden fees.
