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.
Shirofune Integrates Reddit Ads for Streamlined Campaign Management
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. The release complements Shirofune’s existing support for platforms including Google, Microsoft, Meta, TikTok, X (formerly Twitter), LinkedIn, and leading e‑commerce and analytics tools.
Amazon Ads unifies buying tools, boosts AI in campaigns
At its unBoxed conference, Amazon Ads announced major platform changes, renaming its unified platform to Amazon Ads Agent and launching Full-Funnel Campaigns and DVA+. These products aim to collapse silos between sponsored ads, programmatic display, video, and TV buying, while giving Amazon's AI a larger role in planning, execution, and optimization. Advertisers can specify objectives, budget, and creative, with Amazon handling execution, making programmatic advertising more accessible to a wider range of advertisers. DVA+ offers a simplified interface for less experienced buyers with advanced settings for agencies. However, automation raises transparency concerns, especially amid FTC and state attorney general lawsuits alleging secret auction surcharges. Amazon disputes claims and has not committed to full auction-level transparency in new tools, prompting observers to advise caution and emphasize the need for advertisers to interrogate auditability, third-party data integration, and fee structures.
