Influence agency in Paris

Influencer marketing reached €587 million in France in 2025, up 13.1%, with an average return of €8 for every €1 invested. What matters is activating the right creators, with the right method.

An influence agency is a specialised communications agency that designs, orchestrates and measures campaigns with content creators to build a brand's awareness, preference and sales on social platforms.

At Matriochka, 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 influence agency is a company that designs and runs influencer marketing campaigns for brands, from strategy and creator selection through to execution and results measurement. Since 2014, Matriochka has run campaigns for more than 300 brands, including NIVEA, Volvo, Spotify and Amazon, in France and in more than ten countries.

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

A platform is a self-service tool: you search a creator database and manage the campaign yourself. An agency brings a team, a strategy and full execution — creator sourcing, anti-fake due diligence, negotiation, briefing and reporting. That is why 90% of our clients work with us on annual engagements.

How do I choose an influence agency?

Look at its experience, its client references, how it selects and vets creators, and its ability to measure return on investment. Ask for detailed case studies with real KPIs. We detail all the criteria in our guide: how to choose the best influencer marketing agency in France.

Do you work with micro and macro-influencers?

Yes. We activate every profile, from nano-influencers to celebrities, depending on your objectives — often combining both in a single campaign: the macro-influencer creates reach, the micro-influencers drive engagement. Read our comparison: micro-influencers vs macro-influencers.

Which sectors do you work in?

Beauty, gaming, food, luxury, retail, health and tech, among others. We have activated Twitch communities around Call of Duty, run international campaigns for NIVEA and worked for food brands such as Panzani. See our campaigns.
