What Fairy does
Fairytech is a South Korean B2B SaaS company founded in October 2021 that operates an on-device AI marketing platform for card/payment apps, telecom apps, and mobile applications. The company's core product is a sub-2MB Edge SDK that analyzes user behavioral patterns directly on the smartphone to detect real-time purchase intent and trigger personalized cashback offers and push notifications — with all inference and data processing occurring within the device and no information transmitted to external servers. The architecture is anchored by 3 registered patents in On-Device AI held by co-founder and Tech Lead Jiwon Shin, and the company reports deployment across 10M+ devices with 50+ partner advertisers connected through its affiliate network.
The platform is delivered through three vertical-specific solutions: a Card & Pay App Solution targeting Korean credit card and payment apps, a Mobile App Solution for non-financial mobile apps, and an Advertiser Targeting Solution for brands seeking verified high-purchase-intent consumers. The SDK is paired with integrated modules including a Cashback Web monetization layer, an Admin Console for campaign management, and a real-time Analytics Dashboard. Fairytech claims performance benchmarks of 27% CTR, 78% conversion rate, and up to 400% ad revenue growth versus general affiliate marketing, with 90% W4 retention for users receiving cashback benefits.
Fairytech generates revenue primarily through managed advertising and affiliate/commission arrangements: the company handles ad sales, targeting, delivery, and revenue settlement on behalf of partner apps in exchange for a share of resulting transaction revenue. Pricing is custom and not publicly disclosed, sold via direct enterprise sales with a ~3-week onboarding cycle from needs assessment through SDK integration. The customer base is concentrated in Korean financial services (Samsung Card, Shinhan Card, Lotte Card, IBK Corporate Card, Hana Card) and Korean telecommunications (SKT, KT, LG Uplus), with a single healthcare deployment via Nudge Healthcare's Cashwork app. Headcount is approximately 9–10 employees, total disclosed funding is roughly $3.7M across seed (July 2023), TIPS (July 2023), Pre-A (May 2025), and an LG Uplus-led round (July 2025), and monthly revenue reportedly exceeded 100M KRW (~$75K USD) as of early 2026.

Fairy product offering
Product offeringCore offering
Fairytech provides an on-device AI-powered marketing SDK platform that enables mobile apps (card/payment apps, telecom apps, lifestyle apps) to deliver real-time purchase-intent-based push notifications and cashback offers. The proprietary Edge AI processes all user behavioral data within the smartphone without server transmission, detecting purchase intent moments to deliver targeted ads at optimal timing. Fairytech handles the complete ad operations pipeline—from advertiser acquisition to targeting, delivery, and revenue settlement—while partner apps simply integrate the ultra-lightweight (under 2MB) SDK.
Product overview
Fairytech is an on-device AI marketing platform built around its proprietary Edge SDK — a 2MB ultra-lightweight software development kit that analyzes user behavioral patterns directly on the smartphone without any data leaving the device. The product portfolio is organized as a core SDK engine (Fairytech SDK) paired with integrated service modules: Cashback Web (monetization web layer), Admin Console (campaign management), and Analytics Dashboard (KPI monitoring). Above this core platform, the company offers three specialized solutions tailored by vertical — Card & Pay App Solution (for financial/card apps), Mobile App Solution (for general mobile apps), and an Advertiser Targeting Solution (for brands seeking purchase-intent audiences). The architecture works as a B2B2C model: partner apps integrate the SDK to unlock real-time behavioral targeting and push-ad monetization, while Fairytech manages ad matching, campaign operations, and revenue settlement on their behalf.

Fairy competitors and assessment
Company assessmentDirect peers
- Airship: Direct peer in mobile push notification marketing and customer engagement. Airship provides push, in-app, and mobile wallet messaging for enterprise apps — overlapping directly with Fairy's push-notification advertising and intent-based monetization, though Airship is cloud-based rather than on-device.
- OneSignal: Direct peer offering cross-channel messaging (push, email, SMS, in-app) for mobile apps. Comparable on push-notification delivery and segmentation, but OneSignal focuses on messaging infrastructure rather than Fairytech's behavioral-intent ad monetization layer.
- Iterable: Direct peer in cross-channel marketing automation with strong push-notification and segmentation capabilities. Comparable target customer base (consumer apps and financial services), though Iterable operates cloud-side rather than on-device.
- CleverTap: Direct peer in mobile-first marketing automation and user engagement with strong APAC footprint. Both target financial-services and consumer apps with retention and monetization solutions; CleverTap is broader in channel coverage while Fairytech is more specialized on push-intent monetization.
Broad incumbents
- Braze: Broader incumbent in cross-channel customer engagement and lifecycle marketing. Competes for the same enterprise marketing budget as Fairytech but is a horizontal platform with email, SMS, and web channels; Fairytech is more verticalized around on-device push monetization for card/payment apps.
- AppsFlyer: Broader incumbent in mobile measurement, attribution, and marketing analytics. Competes for the same CMO/marketing-ops budget at app publishers and overlaps in advertiser-side targeting, but AppsFlyer is an attribution layer rather than an ad-delivery and monetization platform.
- Adjust: Broader incumbent in mobile measurement and fraud prevention (now part of AppLovin). Comparable in serving app publishers and advertisers with marketing analytics, though Adjust is measurement-focused and operates cloud-side versus Fairy's on-device AI approach.
- Branch: Broader incumbent in mobile linking, attribution, and deep linking. Overlaps in serving app publishers with growth and engagement tooling, though Branch focuses on attribution and linking infrastructure rather than on-device behavioral ad monetization.
- InMobi: Established mobile ad platform with global reach across in-app, video, and programmatic. Competes for the same advertiser demand that funds Fairytech's affiliate revenue share, though InMobi is a horizontal ad network rather than a card/telco-focused SDK.
Emerging players
- Moloco: Programmatic mobile ad network and DSP with strong app-monetization focus. Comparable in monetizing app user bases through machine learning targeting, though Moloco is cloud-side programmatic versus Fairy's on-device behavioral intent approach.
