NBT

NBT operates a mobile advertising model built on two supply sources: owned consumer inventory and integrated partner inventory. It creates value by converting high-attention mobile surfaces, such as lock screens and offerwalls, into monetisable ad placements, then matching that inventory with advertiser demand for engagement and performance outcomes. The business therefore combines elements of adtech infrastructure, media monetisation, and performance advertising intermediation.

NBT INC. is a South Korean mobile advertising company operating consumer-facing and partner-integrated advertising products. Its best-known product, CashSlide, turns the smartphone lock screen into ad inventory and rewards users for engagement, while Addison Offerwall provides rewarded advertising placements inside partner applications. In practice, NBT sits between advertisers seeking mobile performance and app or owned-media environments supplying incentivised user attention.

The company makes money from advertiser spending on mobile campaigns, particularly performance-oriented and incentivised formats. Its customers appear to include brands, agencies, app publishers, and platform partners that want high-visibility mobile placements or monetisation tools, while end users interact with the ad experiences through reward-based mechanics rather than paying directly.
