How to choose an AI media buying platform that works across channels.

If you are looking for an AI media buying platform or an AI agent for paid media, you will find tools built for very different jobs: creative production, Meta automation, search toolboxes and enterprise retail media suites. Six questions separate them, and each comparison below sets one of them against Nupact.

The short version

An AI media buying platform should change budgets, bids and pacing on Google Ads, Meta, TikTok and Amazon Ads from one view, and move money between them with a forecast. Before you buy, check six things: actions across channels, autonomy levels with guardrails, an audit trail with revert, reporting reconciled against your own data, incrementality testing, and where the vendor is built and hosted. Nupact, the control layer for paid media built in Berlin, was designed around all six.

Buyer's checklist

What should a cross-channel advertising platform do?

Use these six as vendor questions. Each one has a short test you can run in the demo, and the answer Nupact gives.

01

Act on more than one platform

Reporting on four platforms and acting on one leaves the biggest decision, the split between them, to a spreadsheet. Nupact acts on Google Ads, Meta, TikTok and Amazon Ads, and monitors DV360, The Trade Desk, Microsoft Ads, LinkedIn Ads and others.

AskCan you move budget from a Google campaign to a Meta campaign in one approved action?

02

Let you set the autonomy level

Ask for autonomy you can set campaign by campaign. Nupact has three levels (alert only, propose and approve, full autonomy inside guardrails) set per campaign and per action type, with limits such as a ±15% cap on daily budget changes without approval.

AskCan Brand-Search stay on approval while pacing fixes run on their own?

03

Keep a receipt for every change

Six months from now someone will ask why budget moved on a Tuesday. Nupact logs the trigger, reasoning, confidence, approver and outcome of every action, rejected proposals included. Every row carries a Revert control.

AskShow me who approved last week's changes, then undo one of them.

04

Reconcile against your own data

Google, Meta and TikTok can each claim the same conversion. Nupact shows platform-reported and reconciled numbers side by side, against GA4, Shopify, your CRM or your warehouse, and keeps the gap visible in every report.

AskWhat does Meta claim for last month, and what did our own data record?

05

Test what is incremental

Attributed numbers can over-credit a channel, retargeting most of all. Nupact runs a feasibility check first, then regional tests and holdouts on your own customer list, and checks the lift studies the platforms run against your revenue. A daily incrementality-adjusted number, labelled with its test and that test's age, feeds every budget proposal. How the tests run.

AskWhich test does this ROAS figure come from, and how old is it?

06

Be built and hosted where your data rules apply

For European advertisers, processing location comes up in legal review before anything else. Nupact GmbH is in Berlin, and the product is built and hosted in the EU, aligned with GDPR and the EU AI Act.

AskWhere is our ad and conversion data processed and stored?

What do people ask when choosing an AI media buying platform?

What is an AI media buying platform?

An AI media buying platform is software that watches your ad accounts and changes budgets, bids, pacing or creative on your behalf, either by proposing changes for approval or by acting on its own within limits. The useful ones explain each change and let you decide how much it may do without asking.

What makes a cross-channel advertising platform different from a dashboard?

A dashboard shows Google, Meta, TikTok and Amazon Ads side by side. With a cross-channel platform, a budget move from one of them to another is a single approved action with a forecast, applied in both accounts when you click.

Should an AI tool be allowed to change budgets without approval?

Only where you have decided it can. Start on alerts, move routine actions such as pacing corrections to approval, and grant full autonomy only inside guardrails like a daily change cap and a monthly spend ceiling. Keep sensitive campaigns on approval.

Does Nupact act on every platform it connects to?

No. Nupact changes budgets, bids, pacing and creative rotation on Google Ads, Meta, TikTok and Amazon Ads. DV360, The Trade Desk, Microsoft Ads, LinkedIn Ads, Snapchat and other connected platforms are monitored and reported on.

How long does it take to get started with Nupact?

About a week to alerts. The first audit arrives on the day you connect, Nupact learns each account's baseline over the next few days, and alert-only monitoring starts from day five.
