Influence agency

We build every campaign with a five-step methodology. First, data: we analyse your market, your audiences and the communities where your brand has something to gain. Then the idea: we turn that reading into a creative concept, the one that makes creators want to take up the subject. Next comes the ecosystem: we choose the right creators and the right platforms, from Instagram to TikTok, from Twitch to YouTube. Then reach: we orchestrate distribution to hit the right audience at the right moment, while driving sales. Finally the KPIs: we measure performance and hand you a clear report your leadership can read.

Strategy and influence consulting

We build your roadmap: objectives, target audiences, choice of platforms, type of creators, budget. You leave with an actionable plan, not a deck that gathers dust in a drawer.

Influencer campaigns

We run the full campaign: creator sourcing, anti-fake checks and due diligence, negotiation, briefing, production follow-up and reporting. We work with UGC, micro-influencers and high-reach creators alike, depending on your objectives.

Integrated PR and influence

We combine influence and PR within a single campaign when it makes sense. A message carried by both journalists and creators gains credibility and reach. It is one of the reasons we brought these two disciplines together from the agency's first day.

Social media and content creation

We produce and adapt the content that feeds your platforms and extends a campaign's life, from short formats to the reuse of creator content.

We work across many fields: beauty, gaming, food, luxury, retail, fashion, health and tech. This range keeps us away from one-size-fits-all recipes. A beauty campaign is not run like a gaming activation, and our teams know the codes of each sector. We have activated Twitch communities around Call of Duty, supported consumer brands such as NIVEA, and worked for food brands such as Panzani.

Since 2014, we have supported more than a hundred brands. Among them: Nivea, Volvo, Instagram, Amazon, Leroy Merlin, Eucerin, Guerlain, L'Oréal Paris, Xbox, Spotify, Kenvue, Panzani, Picard and the L'Oréal Foundation.

→ We are an independent agency, which gives us the agility to decide quickly and stay free in our recommendations. The agency is led by its two founders, Elodie Monchicourt-Lecuyer and Charlie Trouillebout, who get personally involved with every client. Together they bring more than forty years of experience in communication and digital marketing.

→ We rely on a leading-edge technology and AI stack. These tools feed every stage of our work, from creator sourcing to performance analysis, and let us decide on solid data rather than impressions.

→ Our standards come from the methods of major advertising agencies. We apply the same rigour of framing, production and measurement to influence, without losing its spontaneity. The industry also recognises our creative strength: we design campaigns that creators want to carry and that audiences remember.

→ We have made the fight against fake followers a constant requirement. Before every collaboration, we run thorough due diligence on creators: audience authenticity, real engagement rates, history of their public statements, and fit with your brand's values.

→ Our roots are both French and international. Based in Paris, we operate in more than ten countries through a network of independent consultants across Europe, North and South America and Asia, to support our clients wherever their audiences are.

The budget depends on your objectives, the number of creators and the platforms you activate. A campaign with a handful of micro-influencers does not cost the same as a national programme with high-reach creators. We detail the price ranges in our dedicated guide: how much an influence campaign costs in 2026.

What is an influence agency?

An agency that helps brands design and run their campaigns with influencers, from strategy through to measuring results.

What is the difference between an agency and an influence platform?

A platform is a tool you use yourself. An agency brings you a team, a strategy and full execution.

How do I choose an influence agency?

Look at its experience, its client references, how it selects creators, and its ability to measure return on investment.

Do you work with micro and macro-influencers?

Yes. We choose profiles according to your objectives, sometimes combining both in a single campaign.

Which sectors do you work in?

Beauty, gaming, food, luxury, retail, tech and beyond. Our multi-sector experience is one of our strengths.
