APAC is not one market — it is a dozen with different maturity levels, regulatory frameworks, and consumer behaviors. Having built monetization products at InMobi serving APAC publishers, I have learned to respect this complexity.
Market Segmentation
Mature markets (Japan, Australia, South Korea) have sophisticated ecosystems comparable to the West, with CPMs of $5-15 display and $15-40 video. Growth markets (India, Indonesia, Philippines, Vietnam, Thailand) are scaling rapidly with lower CPMs but massive volume. Emerging markets (Myanmar, Cambodia, Bangladesh) have early-stage programmatic. At InMobi, our exchange strategy recognizes these tiers — optimizing differently for Japanese publishers (per-impression yield) versus Indian publishers (volume efficiency).
Mobile-First Reality
APAC is overwhelmingly mobile-first. In India, Indonesia, and Philippines, mobile accounts for 85%+ of traffic. This means mobile-optimized formats, minimal ad weight, and identity solutions working without cookies — device IDs, first-party data, probabilistic matching. InMobi exchange processes significant global in-app inventory, and APAC supply is a core strength with richer SDK-based signals.
CTV Across APAC
Japan and South Korea have high smart TV penetration with established CTV ecosystems. India is in rapid growth. Southeast Asia is earlier stage but accelerating as affordable smart TVs flood markets. At InMobi, we build CTV capabilities serving the full spectrum — mature markets needing sophisticated podding to growth markets needing basic VAST compliance.
DSP and Regulatory Landscape
Global DSPs dominate APAC buying — The Trade Desk expanding aggressively in Southeast Asia, DV360 leveraging Google ecosystem, Amazon DSP growing. Regional DSPs serve domestic advertisers in Japan and China. For our exchange, connecting both global and regional demand is critical. Privacy regulation is fragmented: Japan APPI, Korea PIPA, India DPDP, Singapore PDPA, Australia Privacy Act — our exchange includes geo-aware privacy compliance.
Building for APAC
At InMobi, my focus is exchange products serving APAC diversity — multi-currency support, multi-language contextual intelligence, region-specific privacy compliance, and demand routing optimized for each market unique buyer composition. An exchange globally capable but locally intelligent. That is what I bring.
Building Toward the Future
At InMobi, where I lead Web and CTV Exchange product strategy, every aspect of this topic connects to our exchange product roadmap. The decisions we make about auction design, signal enrichment, demand routing, and yield optimization are all informed by deep understanding of these fundamentals. Having built monetization systems scaling to $200M+ at Glance, I know that getting the basics right compounds into massive revenue impact at scale.
The programmatic industry is evolving toward AI-native, server-side, cross-surface architecture. By 2030, exchanges will consolidate, AI agents will participate in auctions, attention-based signals will supplement viewability, and CTV will be the dominant ad surface. The product builders who understand today's fundamentals deeply — and invest in building for tomorrow's requirements — will lead this transformation. That is exactly what I am doing at InMobi and at adsgupta.com, where I am building AI-powered advertising intelligence tools drawing on everything I have learned across Google, Automatad, Glance, and InMobi over the past decade.
If you are building in programmatic advertising, I encourage you to go beyond surface-level understanding. Read the OpenRTB specification. Study bid request logs. Analyze auction dynamics. Trace the supply chain from publisher to advertiser. This depth of understanding is what separates good ad products from great ones — and it is the perspective I bring to everything I build.
