Introduction

Thousands of creators. Multi-market reach. Paid-ready content in days.

In just 30 days, AMT transformed Le Petit Lunetier’s influencer marketing workflow into a fully automated, data-driven creator engine. What was previously a fragmented, manual process became a repeatable system that delivered measurable paid media results across multiple European markets and languages.

Using AMT, LPL’s marketing team was given easy access to hundreds of creators activated in parallel, organic content ready for paid campaigns within days, and real-time dashboards to track ROI by persona, product line, and creative format.

The challenge: Optimizing influencer content for paid media performance

Le Petit Lunetier, a premium French eyewear brand, was expanding into France, Belgium, and Switzerland. While influencer marketing could drive awareness and engagement, scaling campaigns with measurable paid media lift presented several challenges.

With AMT, LPL’s marketers were able to easily answer revenue-driving questions like:

• Which creators drive the highest CTR and conversion rates?
• How can influencer content be rapidly turned into paid-ready creative with usage rights?
• How can multilingual campaigns across seven markets be executed without expanding internal teams?
• How can ROI be tracked in real time to optimize ad spend quickly?

Before adopting AMT, the team spent 10-15 hours per week manually sourcing creators, negotiating terms, tracking posts, and collecting assets. Campaign iteration took 3-4 weeks from creator activation to paid media deployment, slowing testing and ROI optimization.

The solution: Creating a high-velocity, fully automated creator engine

AMT implemented a persona-driven, AI-supported influencer engine to generate paid-ready content at scale. All tasks—from creator discovery and outreach to asset collection, translation, and reporting—were automated.

This allowed the Le Petit Lunetier team to focus on paid media strategy, creative testing, and ROAS optimization, rather than manual execution.

Persona-driven creator selection for performance insights

Creators were mapped to specific target personas, including fashion-forward urban professionals, eyewear enthusiasts, and lifestyle micro-influencers. Each creator was vetted for:

• Average engagement rate: 4.5% or higher
• Audience authenticity: over 90% real followers
• Historical performance metrics: verified ROI in similar campaigns

This ensured that content going into paid media campaigns was predictably high-performing, reducing wasted ad spend.

Multilingual outreach and activation at scale

AMT automated outreach across seven markets in three languages (French, Dutch, German), ensuring personalized, on-brand messaging. Paid media teams benefited from:

• 2,000 creators activated in 30 days
• 100,000 outreach emails sent automatically
• Seven markets supported simultaneously
• Three languages managed without additional headcount

Campaign launch speed increased fivefold, reducing the time from initial creator outreach to paid-ready asset deployment from 3-4 weeks to 5-6 days.

Zero-touch logistics and ready-to-go content

AMT handled all operational tasks, including contract negotiation, follow-ups, product shipping, collection of creative assets, compliance tracking, and management of usage rights.

1,500 organic posts were collected and rated paid-ready, providing a continuous supply of creative content for ad campaigns.

Real-time dashboards for actionable paid media insights

All content, performance metrics, and audience data were automatically fed into live dashboards, allowing marketers to monitor:

• Per-creator CTR
• Engagement rate per post
• Top-performing creative formats
• Persona-level ROAS projections
• Paid-ready asset availability

This eliminated manual reporting and enabled rapid iterative testing, increasing campaign efficiency.

Paid media teams can rapidly test messaging, optimize product-persona combinations, and deploy top-performing content into campaigns without delays.
