École Polytechnique wanted to attract qualified tech entrepreneurs for its X-UP incubation programs. Starting from a brand-new LinkedIn Ads account, the goal was to quickly build an efficient lead generation strategy despite a tight timeline and hard-to-reach targets.
Optimizing the lead generation strategy
Through a series of rapid tests and close analysis of the results, Junto identified Document Ads as the top-performing format. Campaigns were adjusted wave by wave, with sharper segmentation by program (Create vs. Scale), significantly improving performance while cutting costs.

Deploying an acquisition strategy on LinkedIn
Starting from a blank ad account and a tight timeline, Junto launched a first LinkedIn campaign to rapidly test different formats and target deeptech profiles. This initial work identified the best-performing levers and informed the optimization of subsequent campaigns.
Refining targeting and segmenting by program
Building on the learnings from the first campaign, audiences were refined around the incubator's two tracks: X-UP Create (early-stage founders) and X-UP Scale (startups raising funds). Precise targeting reached qualified profiles aligned with the requirements of both programs.
Optimizing formats for better performance
Traditional formats (image, lead form) were set aside in favor of Document Ads, which proved more engaging and higher quality. The result: a CPL cut by 25% between the two waves, and markedly better lead quality.
Reaching their goals
The partnership between École Polytechnique and Junto generated qualified leads while significantly reducing acquisition costs
With Junto's support, École Polytechnique's X-UP incubator was able to structure two high-performing LinkedIn campaigns despite starting with no advertising history. By progressively refining the targeting and focusing on the most effective formats, the team recruited entrepreneurial profiles aligned with the expectations of the Create and Scale programs.
By building on the learnings from the first wave, the second campaign cut CPL by 25% while maintaining excellent lead quality. This iterative approach validated a repeatable methodology for future campaigns.
