Programmatic
Viant
Viant is a programmatic advertising platform whose Adelphic demand-side software lets marketers plan, buy, and measure media across connected TV, mobile, desktop, audio, and digital out-of-home from one interface. It emphasizes people-based and cookieless addressability through its household identity graph, plus built-in measurement and supply-path tools. Mid-market advertisers and agencies use Viant to run omnichannel campaigns, activate first-party and partner data, and reconcile reach and frequency across screens without stitching together several disconnected buying tools.
What it does
Viant's Adelphic platform is a self-service demand-side platform for buying programmatic media across connected TV, mobile, desktop, streaming audio, and digital out-of-home in one place. Instead of cookie-based targeting alone, it leans on a household identity graph to support people-based and cookieless addressability, so advertisers can manage reach and frequency across the screens a household actually uses. The platform bundles campaign planning, bidding, audience activation from first-party and partner data, supply-path controls, and measurement, including outcomes and incrementality reporting. It is positioned for mid-market brands and agencies that want omnichannel programmatic buying and unified reporting without operating multiple disconnected DSPs and measurement vendors.
Where it fits
Viant sits at the campaign-launch stage of programmatic, executing cross-channel media buys and measuring outcomes against first-party audiences.

Beginner notes
- Start with clear audience definitions and first-party data; identity-based buying is only as good as the inputs.
- CTV minimums and inventory differ from open-web display — plan budgets per channel rather than as one pool.
- Use its built-in measurement to validate incrementality instead of judging CTV on click metrics alone.
