Index Cloud is our neutral compute environment for decisioning closer to when impressions originate. Partners deploy their own models, data, and logic in isolated infrastructure adjacent to the transaction—providing the autonomy of the public cloud, but without the latency, signal loss, cost premiums, and added overhead of running outside from the auction.

Index Cloud is our neutral compute environment for decisioning closer to when impressions originate. Partners deploy their own models, data, and logic in isolated infrastructure adjacent to the transaction—providing the autonomy of the public cloud, but without the latency, signal loss, cost premiums, and added overhead of running outside from the auction.

[H2] Decisions made closer to the impression are smarter from the start

[H3] Your value stays yours
Deploy your own models, data, and decisioning logic without giving up control of your strategy or IP.

[H3] Autonomous by design
Each partner runs in isolated infrastructure with tightly permissioned access, cryptographically signed code, and independent execution.

[H3] Objective platform
Index provides the environment, not the strategy. We do not define your logic or intermediate your unique value.

[H3] Closer to the impression
Run against the signals available at decision time without external round trips, unnecessary latency, or signal loss.

[H2]
See what’s possible atop the Index Cloud

[H2] Audience and signal enrichment

Apply your own audiences, first-party data, and models at impression time.

[IMG: Illustration for deal activation]

[H2] Deal activation

Use your own scoring and decisioning logic to shape supply paths and activate deals.

[IMG: Illustration for content classification]

[H2] Contextual and content classification

Run your own models against live content and placement signals for streaming, web, and app supply.

[IMG: Illustration for impression valuation]

[H2] Impression valuation

Evaluate each opportunity with your own pricing and response logic in real time.

[IMG: Illustration for DSP hosting]

[H2] DSP hosting

Host an instance of your bidder directly atop the Index Cloud, cutting out network costs and giving you scalable, low-latency access to the exchange.

[H2] The Index Cloud purpose-built for programmatic

[H3] A neutral platform for partner intelligence

Every partner brings distinct value to Index Cloud. We provide the common compute layer while you retain autonomy over your own models, logic, and commercial strategy.

[H3] No external hosting costs required

There’s no infrastructure for you to maintain outside the exchange.

[H3] Performance at the source

Closer proximity to the impression means your models run on richer signals, faster, and at greater global internet scale.

[H3] Immediate scale

Your unique business value has immediate, scaled access to 3,000+ global media owners spanning streaming TV, web display, online video, native, and mobile app.

[H3] Our infrastructure, not public cloud

The Index Cloud is purpose-built for programmatic at scale and runs within Index’s own global data centers without any third-party cloud dependencies.
