Shirofune Integrates With Amazon DSP
Shirofune, a Japanese digital advertising automation platform, announced an integration with Amazon DSP that lets advertisers access Amazon’s programmatic inventory (including Prime Video and Fire TV) through the Shirofune interface. The integration targets flexible use cases such as spot campaigns, pilots, and pre-scale testing. Shirofune says the connection brings its automated bidding optimization to Amazon DSP accounts, letting advertisers set budgets and target ROAS (ACoS) while minimizing manual bid management. The deal also emphasizes transparency: aside from Shirofune’s platform fee, there are no additional management fees or margins; advertisers pay media costs directly to Amazon and can retain full account access and permissions. Mitsunaga Kikuchi, Shirofune’s CEO and founder, highlighted increased access to advanced DSP capabilities for advertisers of all sizes.
Integration expands programmatic access to Amazon DSP via an automated bidding platform, increasing advertiser options and transparency—relevant to programmatic buying but not a major platform policy shift.

Shirofune announced integration of Reddit Ads into its digital advertising automation and management platform, enabling U.S. advertisers and agencies to plan, manage, and optimize Reddit campaigns from the same interface they use for search, social, and e-commerce channels. The integration centralizes Reddit campaign controls, allows Shirofune’s automation engine to allocate budgets and adjust bids, supports funnel-aware strategies (top/mid/bottom-funnel objectives), and surfaces cross-channel performance for incremental measurement. Mitsunaga Kikuchi, Founder and CEO of Shirofune, said the integration helps advertisers plug Reddit’s community-driven inventory into broader automated workflows without added manual effort.

Amazon Targets Netflix Ads with New Audience Tool
Amazon Ads announced that starting next quarter US media buyers will be able to use Amazon Audiences to target Netflix campaigns running through the Amazon DSP. The capability builds on Netflix’s September decision to make inventory programmatic in the Amazon DSP and lets advertisers cross-reference Amazon’s commerce and browsing signals with logged-in Netflix accounts. Amazon says its authenticated identity graph covers roughly 90% of US households. The move is positioned to help marketers treat streaming as a full-funnel channel by tying impressions to purchase intent and conversions. Amazon also highlighted recent ad‑tech upgrades such as Campaign Manager and a creative agent, and noted agency partnerships (including Omnicom Media) aimed at improving frequency capping and ad performance.
