The 6 Best Influencer Marketing Consultants in France in 2027

Choosing among the best influencer marketing consultants in France means handing the choice of creators, the briefs, the negotiation and the measurement of results to a single person rather than to an agency team. The framework has tightened: the French law of 9 June 2023 regulates commercial influence, and the ARPP, the French advertising self-regulatory body, awards a Certificat de l'Influence Responsable (Responsible Influence Certificate) after online training and an exam on the legal framework and ethical rules, as explained on the ARPP's page on responsible influence. A good consultant knows these rules and makes sure they are applied in your collaborations. This ranking brings together only independent consultants, checked one by one, and says for each which type of brand they suit.

Influencer marketing consultant or agency: what changes for your brand?

An independent influencer marketing consultant is both your point of contact and the person who does the work. The first call, the choice of creators, the briefs, the negotiation and the reading of results all go through the same person, with no project manager or assistant between you and your campaigns.

This format has three advantages for a DNVB, a start-up or an SME: contact is direct, fees are often lower than at an agency because there is no team to fund, and the consultant has no in-house roster of creators to place. It also has two limits: one person cannot contact, follow up and track hundreds of creators every month, and their absence slows everything down. The consultants on this page therefore often work with your team, your influencer platform or independent partners, who take on part of the execution.

If you run campaigns with several dozen creators at a time, or if you need video production, events or a presence in several countries, an agency is often a better fit. Our ranking of the 10 best influencer marketing agencies in France (2027) covers that case.

How did we rank these influencer marketing consultants?

Five criteria, in this order, applied to what each consultant publishes on their own site. Every site on this list was reviewed on 17 October 2026, and this page is scheduled for review every 90 days.

1. Influence is the core business. Consultants who present influencer marketing as their specialty come before those who list it among community management, press relations or content creation services.

2. Proof you can check yourself. A book with a publisher, courses at named schools, a detailed career with well-known players in the sector and regularly published campaign analyses count for more than a return on investment shown without a source.

3. An offer you can read before the first call. A described format (duration, deliverables, commitment), a clear explanation of what the consultant does and what remains your responsibility, and a price when one is published.

4. Fit with a type of brand. A brand looking for awareness, an online retailer that wants measured sales and a B2B company do not need the same support. We state for which case each profile is most useful.

5. Real, independent activity. A live website, the person's name displayed, consistent legal notices, and work as a consultant who carries out the engagements personally. A firm that presents itself as an agency, with a team of consultants and a careers page, was left out even when it remains small.

What we deliberately did not do: we did not repeat the revenue figures, claims of multiplied sales or numbers of activations published by the consultants, because there is no way to verify them from outside. Rankings of influencers or experts listed by a consultant on their own site did not count as proof. We did not audit any client campaign.

Why this edition has six profiles and not ten. In France, influencer marketing advice goes mostly through agencies, platforms and profiles on Malt or LinkedIn, and rarely through an independent consultant with a site in their own name. We left out a Brittany-based firm that presents a team of consultants and is hiring, a Provence-based firm that presents itself as an agency with several offices, a Paris-based influence and podcast studio, freelance community managers and a young Lyon-based firm for which influence is one service among others, consultants in SEO, food communication, brand content and press relations who offer influence as an add-on, a site we could not open, and some twenty influencer marketing consultants who only have a profile on a freelance platform or on LinkedIn. Rather than completing the list with unverified information, we publish only the six profiles that meet all five criteria.

The 6 best influencer marketing consultants in France

1. Camille Jourdain

Camille Jourdain presents himself as a freelance influencer marketing consultant and supports brands and start-ups with their influencer and social media strategy, from the Lille metropolitan area. He worked in agencies from 2014 to 2018, as social media manager at 909c and then as head of digital communication at WNP, which acquired 909c in 2017. He is co-author, with Guillaume Doki-Thonon, founder of the Reech platform, of the book « Influence Marketing : stratégies des marques avec les influenceurs » (Influence marketing: brand strategies with influencers), published by Kawa in April 2019, after a first book on Twitter with the same publisher. He has taught social media and influence in higher education since 2010 (ISEG, ISEFAC, ISCOM, ISTC, and occasionally Skema or SUP DE PUB), announced in September 2023 that he had obtained the ARPP's Certificat de l'Influence Responsable, and is a member of the UMICC, the French union of influence and content creator professions. His blog, launched in 2008, is still publishing analyses of influencer campaigns in October 2026, and the Kolsquare platform lists him among the influencer marketing experts to follow. His offer covers influencer strategy consulting (identifying influencers, choosing tools, setting up long-term partnerships), social media, content marketing and event communication. He does not name clients and does not publish a price.

Best for: brands and start-ups that are starting out in influencer marketing or want to structure it with someone who has followed the sector for more than fifteen years, as well as schools and companies looking for a trainer. Since his site names no clients, ask on the first call for examples of recent engagements and how he measures results.

2. Isabelle Duvert

Isabelle Duvert works as an independent consultant through her company ID Conseil, based in Paris, and supports brands that speak to families (childcare products, toys, education, publishing, apps) with influencer marketing and media relations. She comes from the parenting blogosphere: she has run the blog e-zabel.fr since February 2008, named blog of the year by Elle Magazine in December 2008, then co-founded and co-managed the agency Com&Kids, where she created and ran the influence department until May 2020. Her site details her references with names: she has worked with Maxi-Cosi in France since January 2021 (recruiting and managing influencers who are young or expectant parents, a paid campaign, press and influencer events in Paris, Lyon, Bordeaux and Aix), and publishes testimonials signed by managers at Maxi-Cosi, Les Sherpas, Bookinou and Waterplops. She says she measures her campaigns with the Kolsquare platform, rules out creators with inflated followers or engagement, and applies the Studer law on the work of child influencers, the law on commercial influence and the ARPP's recommendations. For press relations, video or community management, she relies on a collective of independents that she presents on her site. She does not publish a price.

Best for: childcare, toy or parent services brands that want a single contact for parenting content creators and for the press. Her work combines influence and media relations: if you are looking only for creator campaigns measured in sales, say so on the first call and ask how she will track them.

3. Domitille Desgranges-Lentz

Domitille Desgranges-Lentz, known on LinkedIn as "Madame Affiliation", has worked as a sole trader under the Affil'Great brand since 2022 and focuses on affiliate marketing and performance-based influencer marketing for e-commerce brands. Her published career starts at media agencies: Carat Interactive and then Dentsu, where she created the affiliate department, then GroupM France as performance marketing director, before several years in Quebec, first at an agency and then as marketing director for an advertiser. She also created Caraocar, a car website for women that was sold to TF1 in 2013. On the influence side, she describes two formats in detail: a two-hour express audit by video call, scheduled within seven days and based on your creator data, to identify the creators who bring in revenue and those who cost money with no return, and monthly management with a three-month commitment (tracking sales by creator through promo codes, tracked links and UTMs, sorting and nurturing creators, negotiation, one-page report). She says she relies on AI agents she built herself for tracking and reporting, and takes on only three or four clients at a time. Her site shows logos of major brands without specifying the nature of each collaboration; according to her career history, some of them, such as Bouygues, Cofidis or Volkswagen, date from her years at media agencies. All her prices are quoted on request.

Best for: online retailers and DNVBs that already send products to creators or pay for collaborations, and want to know how much revenue each one brings in. Her approach starts from affiliate marketing and sales measurement: if your main goal is awareness or brand image, ask her on the first call how she evaluates that type of campaign.

4. Margot Germain (MG Confluence)

Margot Germain set up her firm, MG Confluence, after six years in digital project management, including three and a half years at her last company, to focus on influencer marketing. She presents herself as an influencer marketing consultant and lists her preferred fields: nature, culture, sport, outdoor and agriculture. Her site names the campaigns carried out: influencer strategy for KIOTI France (compact tractors) and for Compo Expert (fertilisers), influencer strategy, social media and press relations for the Saulieu international eventing competition, and the search for a patron and press relations for the DEBRA France association. Garden and farming content creators who have worked with her, notably on collaborations with Iseki France, publish signed reviews, and she says she has managed around fifteen collaborations. She offers two formats described on her site: full support (objectives, targets, profile search, production follow-up, analysis of results) and strategic support that combines training and a first launch, with a selection of two to five creators, for teams that then want to run their campaigns themselves. Her legal notices place her in the Puy-de-Dôme department. Her prices are quoted on request.

Best for: brands of farm machinery, garden, outdoor or equestrian products, and sports events, that want to work with specialist creators rather than lifestyle profiles. Her independent business is recent: ask on the first call which campaigns she ran on her own account and which date from her previous job.

5. Jennifer Réthoré

Jennifer Réthoré works as a sole trader under the name Jennifer Réthoré Consulting and presents herself as an influencer strategy consultant for wellness and mental health brands. Before advising brands, she worked with them as a content creator on these topics, under the account @supersensibilite, and says she has collaborated with brands in this sector for more than four years. Her offer comes in three formats: an audit of past collaborations followed by an action plan, outsourced influencer management (strategy, creator selection, campaign supervision, reporting) and the design and management of a one-off campaign. Her site also describes four types of campaigns she sets up: awareness, product launch, communication around a key moment and ambassador programme. She works from Bordeaux and remotely. She does not name clients and does not publish a price.

Best for: wellness, mental health or sensitive-topic brands that need credible creators and the right message more than a large volume of posts. Since her site names no references, ask for examples of campaigns you can see online.

6. Claire Gervasoni (CG Influence)

Claire Gervasoni works freelance under the CG Influence brand, from Antibes, for brands on the French Riviera and elsewhere. She presents herself as a UGC and influence manager, after several years in communication and influencer marketing at various companies. Her projects page describes named campaigns: influencer strategy and an affiliate network for SuperSmart (food supplements), the launch of the Wake brand with content run through whitelisting, affiliate and gifting campaigns for Nuclever and Happy Detox, influencer recruitment for the launch of the Influly app, a day with eight local creators for a new Jeanne en Provence range, and a local creator campaign for the venue Villa Djunah. She also offers digital strategy, community management and talent management, meaning she supports creators in their partnerships with brands. Her client reviews come from Google. She does not publish a price and offers a discovery call.

Best for: food supplement, wellness or sports brands, as well as venues and brands on the French Riviera that want closely managed micro-influencer campaigns. Since she also represents creators, ask how she chooses the profiles for your campaigns, and which of her projects were carried out as a freelancer.

The six consultants compared on what matters to you

Each cell reflects what the consultant publishes on their site as of 17 October 2026. When a piece of information is not published, the cell says so.

What should you check before handing your influencer marketing to a consultant?

Four points to raise on the first call, whoever the consultant is.

• How creators are chosen. Ask how the consultant checks a creator's audience (country, age, share of inactive followers), how well their content fits your brand, and their past collaborations. A good choice is worth more than a large number of profiles contacted.
• Compliance with the legal framework. The law of 9 June 2023 requires, among other things, that the commercial nature of a collaboration be clearly stated. Ask who drafts the contracts with creators, who checks the disclosure on each post, and whether the consultant knows the ARPP's recommendations.
• What will be measured. Views and likes do not tell you what a campaign brings in. Ask which indicators will be tracked (sales by promo code or tracked link, cost per acquisition, traffic to your site, searches for your brand) and how often you will receive a report.
• Who does the work and who keeps what. Ask whether the consultant contacts and follows up with creators personally, or relies on your team or a platform. Keep ownership of your advertising accounts, and have the period during which you can reuse creators' content in your ads set out in writing.

Where does this ranking stop?

Three limits, stated clearly.

It is based on public information. We read what each consultant publishes and checked that their site was live on 17 October 2026. We did not confirm any client result. A highly skilled consultant who works mainly through referrals, without a site in their own name, does not appear here.

It does not know your brand. The right person to launch a cosmetics brand on TikTok is rarely the right one to get people talking about B2B software on LinkedIn. The Best for lines matter more than the rank number.

It covers independents. If you need a full team (casting dozens of creators, production, events, campaigns in several countries), see our ranking of the 10 best influencer marketing agencies in France (2027). Consultants' offers and availability change quickly: check them on their site before you sign.

What can an influencer marketing consultant do that software cannot?

A consultant makes judgement calls: which creator to choose, what budget to give them, when to end a collaboration that brings in nothing, how to negotiate exclusivity. These decisions require knowing your brand, your market and the creators who matter to your customers. A successful campaign then prompts part of the audience to search for your brand on Google or to ask AI assistants about it. What these people find depends on the content published on your site, and that is often the part small teams leave aside.

That is what Sorank automates: the platform finds the topics your customers search for, writes and publishes articles optimised for Google and for AI assistants, and shows you when an AI assistant cites your brand. Many brands combine the two: the consultant for creators and campaigns, the software so that the site can take over from there.

Conclusion

The best influencer marketing consultant is the one who knows your customers and measures what matters to your brand. To build an influencer strategy or train a team, Camille Jourdain offers the longest perspective and the strongest public proof. For a brand that speaks to parents, Isabelle Duvert publishes the most detailed references. For an e-commerce business that wants to link each creator to its sales, Domitille Desgranges-Lentz offers the most precise service. Margot Germain, Jennifer Réthoré and Claire Gervasoni are solid choices in their respective sectors: farming and outdoor, wellness and mental health, micro-influence on the French Riviera. For campaigns with many creators at once, a specialist agency will be a better fit. And to make sure your site is found on Google and cited by AI assistants when people search for your brand, discover Sorank.
