Audience Data Joins Curated Ad Supply in APAC
Advertisers buying audience-targeted media in North America and APAC can now purchase privacy-conscious segments alongside curated inventory.
Updated on Nov. 2, 2026 in Advertising
AlikeAudience, a third-party audience data provider, has joined Index Marketplaces, the omnichannel platform of Index Exchange. The integration gives buyers access to premium audience segments across North America and APAC, and is announced from Singapore on 2 November 2026.
Why it matters
Advertisers and agencies are looking for addressable audience options that work without third-party cookies, and this partnership packages privacy-conscious audience signals directly into a curated supply marketplace. For operators, it signals that audience data and inventory are increasingly being bought together rather than sourced from separate vendors.
The announcement cites no volume, pricing, or performance metrics, so the scope is described only by geography: premium audience segments across North America and APAC, with third-party MAID data shared across the US, Southeast Asia, and APAC. Buyers evaluating the integration will need to request specifics directly from the parties.
The players

Market Landscape
The move follows the broader shift away from third-party cookies, which has pushed advertisers toward addressable identifiers and curated marketplaces. Pairing audience data vendors directly with supply platforms reflects a trend toward bundled buying rather than separate data and inventory purchases.
Media buyers should ask prospective audience-data partners how their signals are sourced and whether they can be activated alongside inventory on the same platform. Teams evaluating cookieless targeting should compare the regions covered, since the announced scope spans North America and APAC.
The takeaway
Advertising operators should treat audience data and supply as a bundled purchasing decision and check whether a given vendor's coverage matches the regions they actually buy in. Track how cookieless targeting performance is reported by vendors in the next reporting cycle before committing budget.
