ScaleOut

What ScaleOut does

ScaleOut is a programmatic marketing platform — specifically a Demand-Side Platform (DSP) — operated by Supership Inc., a Japanese advertising-technology subsidiary of KDDI Group. The platform enables brand advertisers and marketing agencies to buy display, in-stream video, and audio inventory programmatically, with a deliberate strategic focus on video and audio following the July 2024 exit from display advertising handling. Its core technology comprises a DSP front-end, RTB connections to multiple SSPs (Ad Generation, AJA, fluct, Magnite for DV+ and CTV, PubMatic, and Taboola), proprietary targeting data, and an integrated ad verification stack (brand safety, anti-fraud, viewability) delivered through Momentum, a wholly-owned Supership verification subsidiary. ScaleOut also offers marketing analytics services, including the December 2024-launched '0次分析 the Beyond' (Zero-Analysis the Beyond), which packages data-driven marketing insight as an end-to-end service from strategy through execution.

The platform monetizes primarily through programmatic transaction fees tied to advertiser ad spend managed through the DSP, supplemented by data-driven marketing services delivered on a recurring / consulting basis. Go-to-market is enterprise field sales targeting brand advertisers, marketing agencies, and — via the June 2023 Sansan Eight integration — B2B marketers seeking to reach professional audiences. ScaleOut holds JICDAQ (Japan Digital Ad Quality Certification) buyer and trading/mediation certifications, which serve as procurement-relevant quality credentials in the Japanese market. Customer-specific logos and revenue figures are not publicly disclosed. The unit operates with a small team (1-10 employees) embedded within the broader Supership and KDDI corporate infrastructure that supplies sales, marketing, and shared go-to-market support.

Scale indicators2 records

Recent moves6 records

Expansion highlights5 records

Regional players

• i-mobile: Japanese mobile-focused ad network and DSP offering programmatic buying primarily in the Japanese market. Comparable as a Japan-only programmatic buyer addressing brand advertisers, with mobile-first targeting depth as a regional parallel to ScaleOut's KDDI data advantage.

Direct peers

• Criteo: Publicly traded ad tech company operating a retargeting and performance DSP with significant APAC presence. Comparable as a DSP serving brand and agency advertisers with data-driven targeting, though focused more on commerce/retargeting use cases than ScaleOut's broader in-stream and audio mix.
• The Trade Desk: Global independent DSP that enables programmatic media buying across display, video, CTV, and audio. Directly comparable to ScaleOut's DSP core; competes for the same brand advertiser and agency spend, albeit with much broader geographic coverage and inventory scale.
• Geniee: Japanese ad tech company operating a DSP (including its GenieeDSP product) alongside SSP and ad serving offerings. Directly competes with ScaleOut in Japan for programmatic display, video, and native advertising budgets among Japanese brands and agencies.
• LOGICAD (Dentsu): Demand-side platform operated by Dentsu Group, Japan's largest advertising agency group. Comparable as a Japan-focused DSP with deep agency relationships, integrated ad verification, and premium inventory access; benefits from Dentsu's first-party advertiser data in a similar way ScaleOut benefits from KDDI's.
• FreakOut Holdings: Japanese DSP and digital advertising platform operator. Closest direct competitor in Japan with similar advertiser base (brands and agencies), programmatic buying capabilities, and SSP connections; competes head-to-head for Japanese brand budgets.

Broad incumbents

• Google Display & Video 360: Google's enterprise DSP within the Google Ads ecosystem, offering programmatic display, video, and audio buying integrated with Google's owned inventory and audience data. Broad incumbent competing for the same enterprise advertiser and agency spend; scale and Google data advantage make it the dominant reference point in any Japan DSP evaluation.
• Amazon DSP: Amazon's demand-side platform leveraging first-party commerce and Prime Video/CTV signals. Competes with ScaleOut for brand and agency advertiser budgets globally and increasingly in APAC, with a structurally deeper logged-in audience dataset than any telecom-derived offering.

Others

• PubMatic: Global independent SSP providing programmatic inventory across CTV, mobile, and display. Operates the supply-side complement to ScaleOut's DSP; comparable as an ecosystem participant whose platform ScaleOut integrates with and which sets competitive benchmarks for programmatic technology infrastructure.
• Magnite: Independent sell-side platform (SSP) and CTV technology provider. While ScaleOut is a DSP buyer of Magnite's inventory (DV+, CTV), Magnite operates the adjacent side of the programmatic pipe and is the strategic counterparty for many of ScaleOut's video supply integrations.
