What NBT does

NBT is a Seoul-based ad tech company founded in 2012 and listed on KOSDAQ since 2021, operating Korea's No.1 offerwall network — AdISON — alongside a portfolio of consumer reward apps. The AdISON Offerwall is embedded in 70+ premium Korean platforms including Naver Webtoon, Toss, Baemin, Naver Pay, Kakao Mobility, Bank Salad, and Zepeto, with 148 media partners by end-2025. NBT monetizes via performance-based pricing (CPS, CPE, CPA, and multi-mission formats), earning a take rate on GMV that reached 3,220 billion KRW in 2025 through the shopping affiliate model launched that September — 4x growth from 818 billion KRW in 2024. The company has expanded internationally with launches in North America and Southeast Asia in 2023 and 6 additional countries in 2025.

On the consumer side, NBT operates Cashslide — the world's first smartphone lock-screen rewards app with 27M+ cumulative registrations — along with Cashslide StepUp (savings pedometer), CashFeed (content monetization), Shopping Savings (e-commerce coupons), and Chips (multi-reward app with C2C second-hand coupon trading launched 2025). These apps are unified through a cross-app account and point system, with rewards redeemable for mobile coupons from 40+ partner brands or cash via N Pay. Underlying infrastructure is multi-cloud (AWS, GCP), ISMS-certified, and processes over 300 million daily data events.

The dual B2B/B2C model is reinforced by proprietary technology including the AdISON RTB and audience-targeting platform, the multi-mission advertising format (D7 retention reportedly 15x single-mission), CPS purchase-confirmed settlement with fraud handling (1.99% cherry-picker rate), and the proprietary Pay Grade compensation system. The company has 101-250 employees, operates a wholly-owned NBT Retail subsidiary, and reported 1,063 billion KRW in 2023 domestic AdISON Offerwall revenue.

Direct peers

• Tapjoy: US-headquartered offerwall and rewarded advertising platform integrated into mobile apps. Most direct global comparable to AdISON Offerwall — same product category (offerwall), same performance-based advertiser pricing model (CPA/CPE), and same publisher monetization value proposition.
• Moloco: ML-driven mobile programmatic and app monetization platform operating in performance advertising. Comparable to AdISON in providing performance-based (CPA/CPS) campaign optimization and audience retargeting for app-driven advertisers.
• Buzzvil: Korean lock screen advertising platform and direct competitor to Cashslide. Operates in the same Korean market with the same core product (rewarded lock screen inventory) and shares overlapping premium publisher relationships, making it the closest domestic peer.
• Persona.ly: Mobile ad-tech platform combining programmatic demand with rewarded offerwall formats. Direct comparable to AdISON in offering both performance advertising and rewarded user acquisition for app advertisers.
• Chartboost (now InMobi): Mobile ad network and monetization platform (originally gaming-focused) offering rewarded ad formats including offerwall. Comparable to AdISON in delivering performance-based mobile ad inventory across publisher apps.
• CashWalk: Korean pedometer/reward app competing directly with Cashslide StepUp. Comparable as a domestic reward-based consumer app monetized through embedded advertising, though it does not operate a separate B2B offerwall network like AdISON.

Emerging players

• Pollfish: Mobile monetization platform offering rewarded surveys and offerwall-style formats for app publishers. Comparable in product category (in-app rewarded monetization) but narrower in scope and without NBT's proprietary lock screen inventory.

Broad incumbents

• ironSource (Unity): Major mobile app monetization and ad-tech platform now part of Unity. Comparable to NBT as a broader ad-tech incumbent offering mediation, offerwall, and rewarded video across a global publisher footprint, though with deeper focus on gaming apps.
• AppLovin: Global mobile ad-tech and monetization platform with AXON algorithmic ad ranking and SparkLabs mediation. Comparable as a broad incumbent in mobile performance advertising and rewarded formats, though much larger and more diversified than NBT.
• Digital Turbine: Mobile ad-tech and app install monetization company offering on-device media delivery and programmatic exchange. Comparable as a broader incumbent in mobile ad monetization, though its offering spans carrier-level distribution beyond NBT's offerwall focus.
