The programmatic advertising ecosystem in Asia-Pacific continues to grow and diversify. CTV adoption is accelerating, curated marketplaces are becoming more common and brands are demanding cleaner, more transparent supply paths. Yet most global documentation and tooling conversations are still heavily centred around the US and Europe.
For teams in Southeast Asia – whether on the SSP, DSP, publisher, or agency side – the day-to-day questions look different. You’re dealing with fragmented CTV ecosystems, inconsistent ads.txt adoption across emerging markets, a long tail of regional publishers and buyers asking for proof of quality, scale and transparency.
This guide focuses on practical, APAC-relevant tools that help programmatic teams work smarter. Everything here is actionable – tools you can use immediately to make better decisions about supply, quality, curation and operational workflows.
1. Jounce Media – Reseller Intelligence & Supply Path Transparency
Best for: SPO strategy, reseller path analysis, marketplace cleanliness
Website: jouncemedia.com
Jounce Media is widely considered the benchmark for supply path intelligence. Their work maps out the relationships between direct sellers and resellers, highlighting where inefficiencies or risks exist.
For APAC teams, Jounce is particularly useful when:
- Building a SPO framework for buyers or internal strategy
- Comparing direct vs reseller paths across markets
- Evaluating the “cleanliness” of the supply reaching DSPs
- Supporting curated marketplace decisions
2. SupplyFinder – Supply Path Discovery & Seller Verification
Best for: ads.txt validation, sellers.json checks, real-time supply path discovery
Website: supply-finder.com
SupplyFinder is a purpose-built tool for understanding how programmatic supply is structured. It fetches a publisher’s ads.txt in real time and maps out which SSPs and resellers are authorised to sell their inventory. For APAC teams navigating fragmented supply chains, it provides a fast and reliable way to validate partners.
APAC programmatic teams use SupplyFinder to:
- Verify which SSPs and intermediaries are authorised sellers of a domain
- Identify whether sellers are direct or reseller paths
- Uncover unexpected or unknown resellers
- Check for misaligned or suspicious ads.txt entries
- Confirm supply paths for deals, marketplaces, and SPO initiatives
Because ads.txt implementation varies widely across Southeast Asia, SupplyFinder is especially useful for quick due diligence before onboarding a publisher or setting up a PMP.
3. Pixalate CTV App Rankings – CTV & OTT Quality Signals
Best for: OTT/CTV app legitimacy, IVT/SIVT risk, platform-level trends
Website: pixalate.com/resources/rankings
APAC CTV is highly fragmented: Samsung, LG, Xiaomi PatchWall, Android TV OEMs and regional OTT platforms all coexist. Pixalate’s CTV reports help you make sense of this complexity with:
- App-level rankings across major platforms
- IVT and SIVT risk ratings
- Signals around app quality and ecosystem shifts
Use Pixalate when:
- Evaluating CTV apps included in PMPs
- Prioritising inventory for curated OTT deals
- Supporting client education around APAC CTV fragmentation
4. SimilarWeb – Publisher Traffic & Market Intelligence
Best for: traffic validation, geo insights, scale confirmation
Website: similarweb.com
When a publisher claims millions of users or when buyers ask for market-specific validation, SimilarWeb provides directional traffic insights such as:
- Estimated monthly visits
- Top markets (crucial for SEA campaigns)
- Traffic sources (search, social, referral)
This is especially useful when onboarding emerging publishers or responding to RFPs requiring audience scale benchmarks.
5. OpenSincera – Contextual Intelligence & Domain Categorisation
Best for: IAB classification, contextual curation, clean-list building
Website: opensincera.com
With the gradual phase-out of third-party cookies and growing privacy expectations, contextual targeting is becoming a major strategy. OpenSincera helps APAC teams:
- Classify large domain lists by IAB category
- Build contextually curated PMPs
- Enrich internal publisher databases
- Detect category mismatches in reseller paths
You can integrate OpenSincera into Google Sheets, Python workflows or curation pipelines to support scalable, privacy-friendly supply curation.
