How one agency cut reporting time from 4 hours to 12 minutes with AdNexus

Note: Client and agency names have been changed at their request.

Meridian Performance is a three-person performance marketing agency based in Austin, Texas. They manage paid media for 14 clients across Google Ads, Meta, and LinkedIn — a typical mid-market agency setup. Their total managed spend is around $400k/month.

Before AdNexus, their Monday morning reporting process looked like this:

• Pull last week's data from Google Ads into a spreadsheet (45 min)
• Pull Meta data, reformat to match (30 min)
• Pull LinkedIn data (20 min)
• Consolidate into client report templates (60 min)
• Write performance commentary for each client (45 min)
• QA and send (30 min)

Total: approximately 3.5–4 hours, every Monday, for one person. At their billing rate, that's roughly $400–500 of unbillable time per week, or around $24,000 per year.

What they changed

Meridian connected all 14 client accounts to AdNexus AI in a single afternoon. Each client had their own AdNexus workspace with isolated credentials — no cross-client data leakage.

They then set up a recurring Monday morning prompt for each client workspace:

"Generate a weekly performance report for this client. Include: total spend vs. budget, ROAS by campaign, top 3 performing ads by CTR, bottom 3 campaigns by CPA, week-over-week changes for key metrics, and 2–3 specific recommendations for this week."

Claude pulls live data from all connected platforms, synthesizes it into a structured report, and delivers it in plain English — ready to copy into their client template or send directly.

The numbers after 6 weeks

After six weeks of using AdNexus for reporting:

• Monday reporting time: 4 hours → 12 minutes. The remaining 12 minutes is QA and sending.
• Campaign management actions per week: +60%. With reporting overhead eliminated, the team had time to actually optimize. They made more changes in the first month than in the prior quarter.
• One client's ROAS: +31% in 6 weeks. Direct result of more frequent optimization cycles that were previously impossible given the time constraints.
• Team capacity: One team member who was previously dedicated to Monday reporting now focuses entirely on strategy and client communication.

What surprised them

"We expected the reporting to be faster," said the agency founder. "What we didn't expect was how much better the reports would be. Claude doesn't just pull the numbers — it interprets them. It notices when a trend is unusual and says so. Our clients started commenting that the reports felt more insightful than before."

They also noted that Claude occasionally flagged issues they had missed — a campaign where the conversion window was misconfigured, an ad set where the landing page URL had broken, a budget that had been set to monthly instead of daily.

What they'd do differently

The main lesson: set up the automation rules earlier. For the first two weeks, they were primarily using AdNexus for reporting. It wasn't until week three that they started using it for active campaign management — pausing underperformers, shifting budgets, testing new creative. The optimization results accelerated significantly once they made that shift.

AdNexus AI is currently in early access. If you're an agency managing $50k+ in monthly spend across multiple platforms, it's worth getting on the waitlist.
