B2B · Lead generation · SaaS
French SMB-focused HR Software · Monthly budget: €2,500
The HR SaaS software had been generating leads via Meta Ads for six months with a CPL around €82. The volume was insufficient to properly feed the sales team (3–4 qualified leads per week). The campaign structure relied on a single ad set with overly broad interest-based targeting.
"Our sales team never had this many appointments to process. What really changed was lead quality—we can feel the targeting is more precise.",

B2C · E-commerce · Fashion
Women's Fashion Brand · Online Store · Monthly Budget: €3,000
The fashion e-commerce brand had been stuck at a 1.6x ROAS for several months — below profitability thresholds with 45% margins. Campaigns were optimized for clicks rather than purchases, and creatives featured basic product photography without lifestyle context. The pixel was also misconfigured (duplicate events).
“We almost shut Meta Ads down entirely. Within 90 days, it became our most profitable acquisition channel. The difference was adopting a real strategy instead of simply boosting posts.”

B2B Lead generation & Consulting
Organizational Transformation Advisory · Target: SMEs with 50–500 Employees · Budget: €1,800/month
The B2B consultancy firm struggled with Meta Ads alone for four months, yielding disappointing results: only three to four meetings per month, a CPL of €115, and unqualified leads (independent contractors and SMBs) that didn't match their target mid-sized enterprises. The primary mistake was the lack of targeting by company size and decision-maker function.
"The difference is that we're now talking to the right people. Before, we had curious leads. Now, we have prospects with a real project and a budget."

B2B · Lead generation · Energy Renovation
Energy renovation company targeting homeowner individuals · Monthly budget: €2,000
The energy renovation company relied almost exclusively on Google Ads to generate leads for insulation and heat pumps, facing a high CPL (€84) and insufficient volume to keep their sales team fully occupied throughout the week. Meta Ads had never been seriously tested.
We're now signing more projects starting with fewer leads; up-front qualification has completely transformed our sales team.

Lead generation · 45 days
Organic cosmetics brand · Online boutique · Monthly budget: €1,500
The organic cosmetics brand was stuck at a 1.2x ROAS with traditional product imagery, lacking UGC content and dynamic retargeting. The Meta catalog was not leveraged for shopping cart remarketing.

B2C · Product Info · Online Training
Online Training for Freelancers · Webinar Funnel · Monthly Budget: €2,200
The webinar-to-course funnel was underperforming: low attendance, unnecessary friction on the registration page and reliance on one ad creative for several months.
"We struggled to fill our webinars. Today, it has become our top acquisition channel."

B2B · Lead generation · Legal Services
Business Law Firm Targeting SME Executives · Monthly Budget: €1,200
The firm relied exclusively on word-of-mouth and had never invested in digital advertising, despite its target audience (SME executives) being highly active on Meta.
“We thought advertising would not work for a law firm. Six months later, it accounted for 30% of our new clients.”

B2C · Local · Fitness
Independent gym · Local trade area · Monthly budget: €900
The facility relied on flyers and word-of-mouth, facing strong seasonality with a significant summer slump and zero digital advertising presence.
We filled the venue during off-peak season, something we never achieved with flyers alone.

B2B · Recruitment · Tech
Specialized IT Recruiting Agency · Candidate Sourcing · Monthly Budget: €1,600
Traditional job boards were the sole sourcing channel, proving costly and ineffective for reaching passive tech profiles, resulting in poor application-to-interview conversion rates.
"Meta enabled us to reach passive candidates unavailable on traditional job boards."

B2C · Travel & Tourism
Custom Travel Agency · E-commerce · Monthly Budget: €2,800
The campaigns were generic, lacking destination-based segmentation, and featured nondistinctive creatives compared to major OTAs.
“We used to sell generic trips. Now every campaign tells a distinct destination story, and the results reflect it.”

B2C · Local Services · Wellness
Massage & Wellness Institute · Local Service Area · Monthly Budget: €1,100
The spa previously relied on flyers and walk-ins, with an unpredictable booking schedule from week to week. No digital advertising had ever been tested.
“Before, I never knew what my week would look like. Now my schedule is filled three weeks in advance, and I can finally plan ahead.”
