NBT Offerwall: Korea’s No.1 Platform Losing Money

Korea’s most-used offerwall platform has 11 million monthly active users, counts Naver and Toss among its clients, and controls 86% of its revenue from a single dominant B2B product. It is also, for the third year running, losing money.

That contradiction sits at the heart of NBT (엔비티), the Seoul-based mobile rewards advertising company that built Korea’s leading offerwall business — and has yet to turn a profit from it. As of April 2, 2026, NBT’s share price stood at ₩1,780, down more than 50% from its 52-week high of ₩4,225. The market, in short, has run out of patience.

What Is an Offerwall — and Why Does Korea Love It?

An offerwall is an in-app advertising format where users complete small tasks — watching a video, signing up for a service, playing a game — in exchange for virtual currency, points, or cashback. In Korea, this mechanic plugs directly into a uniquely local phenomenon called 앱테크 (app-tech): the widespread habit of earning micro-rewards through everyday smartphone use. Korea’s high mobile penetration and a culture of coupon-hunting and loyalty points have made app-tech mainstream in a way few other markets can match.

NBT’s flagship B2B product, Addison Offerwall (애디슨 오퍼월), embeds this mechanic inside third-party apps. Partners include Naver Webtoon, Naver Pay, Toss (Korea’s dominant fintech super-app), and Baemin (the country’s largest food delivery platform). In effect, when a Toss user earns points by completing an ad mission, NBT’s infrastructure is running underneath. That embedded position gives NBT structural stickiness — and, in theory, a formidable moat.

However, structural stickiness does not automatically translate into profit.

Three Years of Losses, Deepening Fast

According to a report published by the Korea IR Consultancy’s Corporate Research Center (한국IR협의회 기업리서치센터) — a quasi-public body that produces independent equity research on listed Korean companies — NBT recorded an operating loss of ₩6.5 billion in 2025. That is nearly double the ₩3.3 billion loss posted in 2024, which itself followed a ₩1.9 billion loss in 2023. Revenue also fell 12.2% year-on-year to ₩92.3 billion.

The loss trajectory is accelerating, not stabilizing. That is the detail investors should watch most closely.

Two forces are squeezing the company simultaneously. First, advertisers have pulled back budgets amid a sluggish domestic consumption environment — Korea’s household spending growth has remained soft since 2022, and performance-marketing budgets are among the first to be trimmed. Second, NBT has been spending heavily on overseas expansion and infrastructure, pushing fixed costs higher even as top-line revenue shrinks.

The Global Offerwall Market: A Bright Backdrop Against a Difficult Foreground

The broader market context is, in fact, encouraging. The global offerwall advertising market was valued at approximately $1.2–2.3 billion in 2024 and is projected to reach $4.8–5.3 billion by 2033, growing at a compound annual rate of 10.7–16.7%. Furthermore, data from Unity’s mobile monetization research shows that users acquired through offerwalls have a Day-1 retention rate 45.8% higher than those acquired through standard rewarded video ads. Average revenue per daily active user (ARPDAU) from offerwall converts at $4.04 — versus just $0.15 for video ads.

In other words, the product works. The challenge for NBT is converting market-level tailwinds into company-level cash flow.

Meanwhile, competition from large platforms is intensifying. As Google, Meta, and domestic Korean super-apps build out their own rewards and loyalty ecosystems, NBT’s independent B2B positioning faces structural pressure from above.

NBT Offerwall Goes Global — Slowly

NBT’s international push began in earnest in 2023, when it partnered with Line Webtoon to enter the North American market. The service has since expanded to more than ten countries, including the United States, Thailand, and Taiwan. Notably, NBT has also integrated its offerwall into Zepeto (제페토), the Korean-developed metaverse platform with over 500 million cumulative registered users — a distribution channel that reaches well beyond Korea’s borders.

The overseas business, however, still accounts for only about 4% of total revenue as of 2025. For a company billing itself as a global rewards platform, that figure remains modest. Nevertheless, the overseas segment has reportedly grown at an average quarterly rate of 40% since its launch — a trajectory that, if sustained, could begin to matter within two to three years.

DS Investment Securities analyst Jang Ji-hye noted that “while advertiser budget cuts and rising operating costs have widened losses, a genuine earnings turnaround is expected — driven by structural B2C expansion and the rollout of offerwalls within global platforms like Naver Webtoon and Zepeto.”

The Web3 Bet: Bold or Desperate?

Beyond geographic expansion, NBT is making a more speculative move into Web3 and stablecoin infrastructure. The thesis: Korea’s domestic reward market is estimated at ₩20 trillion (roughly $14.5 billion) in annual value. If NBT can tokenize that reward ecosystem — converting points and missions into blockchain-based assets — it could unlock a new monetization layer that traditional advertising economics cannot reach.

ValueFinder CEO Lee Chung-heon argued that “NBT’s dominant position in its core business, combined with its Web3 and stablecoin infrastructure initiative targeting Korea’s ₩20 trillion reward market, positions the company for a strong earnings rebound in 2026.”

That is a bullish read. In addition, it is a speculative one. Web3 monetization in advertising remains largely unproven at scale, and NBT’s track record of translating strategic ambition into operating profit is, as yet, thin. Investors should treat the Web3 narrative as an option, not a guarantee.

NBT also launched Link Commerce (링크커머스), a shopping affiliate platform, as part of its diversification effort. By contrast to the offerwall core, these adjacent bets are early-stage and unproven in terms of revenue contribution.

What the Stock Price Is Saying

A 50%-plus drawdown from a 52-week high is not just a bad quarter — it is a market verdict. Therefore, the question for investors is whether that verdict is final or premature.

The bull case rests on three pillars: a globally proven product format, deeply embedded partnerships with Korea’s most-used apps, and an overseas growth rate that — if it continues — could reweight the revenue mix within a few years. The bear case is simpler: losses are widening, the domestic market is softening, and new bets in Web3 and commerce are unproven.

For foreign investors looking at Korean tech, NBT represents a specific archetype: a company that genuinely dominates a niche — the NBT offerwall ecosystem is real, and its client list is credible — but has not yet demonstrated that dominance can be monetized at scale. That gap between product leadership and financial performance is, ultimately, what the market is pricing in.

The next twelve months will likely determine whether NBT is a turnaround story or a cautionary tale about niche dominance without profit discipline.
