Winston Score History

The full picture

Boku is a payments technology company that helps people pay for digital services using their mobile phone bill instead of a credit card. Its main product is a "direct carrier billing" platform, which connects app stores, streaming services, and gaming companies to mobile network operators around the world. Major customers include Apple, Google, Sony, and Spotify, who use Boku so their users can charge purchases directly to a phone bill.

Boku makes money by taking a small percentage of every transaction processed through its network. It operates in over 60 countries and has built connections to more than 300 mobile carriers, which is difficult and time-consuming for competitors to replicate. The company's key growth driver is the large share of the global population that still lacks a bank account or credit card but does own a smartphone — expanding into these underserved markets could meaningfully increase transaction volumes over time.
