Best PowerPoint agency: our top 10 agencies in France in 2026

mPrez, founded in 2016 under the name Mister Prez, built its reputation on one conviction: a presentation is won on substance before it is won on form. The agency works in three stages — strategic consulting (audience analysis, message structuring), PowerPoint design, then team training — and it is that first stage that makes the difference on complex topics, where the real problem is not the layout but the order and clarity of the ideas.

The company has reached a scale that is rare in this market: more than 30 experts across Paris, Bordeaux, Lisbon and São Paulo, more than 2,500 clients and more than 10,000 presentations delivered. Its references span every sector: Adidas, Chanel, DHL, Crédit Agricole, Sanofi, Red Bull, PwC, BNP Paribas, Air France, TF1, Vinci or Dyson. The agency displays a 4.9/5 rating from more than 150 verified client reviews.

Another plus: transparency. mPrez publishes ballpark figures — between €2,500 and €3,500 excl. VAT for a standard presentation of 20 to 30 slides, delivered in one to two weeks, with a rush option within 48 hours. Files are delivered fully editable, in PowerPoint, Google Slides, Keynote, Canva or Figma Slides.

Founded in 2015 in Paris by Henri de Berny and Rémi Lassieur, Prezman presents itself as “the PowerPoint agency of the world’s biggest companies” — and its portfolio backs up the claim: Google, Amazon, LVMH, Samsung, Publicis, Accor, Accenture, Visa, Netflix or Vinci are among its references. The team, about twenty people, combines consulting profiles and designers.

Its trademark is a proprietary method that combines strategic consulting, graphic rigor and principles of cognitive psychology to make a message easier to remember. It makes the most sense in contexts where a presentation directly drives an outcome: RFP pitches, executive committee presentations, press conferences or product launches.

La boîte à slides is the veteran of this ranking: the agency has existed since 2002 and claims more than 8,000 projects, at a pace of more than 400 PowerPoint presentations a year. Based in Paris, it relies on locations in Bordeaux, Verdun, Aix-en-Provence, Rennes and Strasbourg, with a permanent team of about a dozen people and a network of around forty specialists.

Its most distinctive argument is its ISO 9001 certification: the agency presents itself as the only one in the world dedicated to PowerPoint to have obtained it. In practice, this translates into documented production processes, which reassures the procurement departments of large groups — ENGIE, Safran, Unibail-Rodamco-Westfield, Perrier, Krys, Adidas, Marriott, Kronenbourg or Nissan are among its clients, with a stated loyalty rate of 85%. The offering goes beyond the classic deck: interactive navigation, motion design, virtual reality seminars, and templates designed for Copilot.

Founded in 2021 in Paris, with an office in Lyon, Histoires & Slides has already supported more than 1,200 clients — a pace that makes it one of the most dynamic agencies in the market. Its promise fits in one line: “a well-designed slide doesn’t decorate your message, it reveals it.” The agency brings together three skills, editorial strategy, graphic design and technical mastery of PowerPoint, structured by its IMPACT© method, which works on the narrative before the visuals.

Its references mix CAC 40 companies, mid-cap firms and scale-ups: EDF, Orange, BNP Paribas, Stellantis, Vivendi, Berluti, Clarins, the Institut Pasteur, Radio France or KPMG. The team is entirely salaried and based in France. Stated budgets range between €2,000 and €8,000 excl. VAT depending on the project, with three to four weeks for a standard project and an express option in 24 to 48 hours. The agency displays 4.9/5 on Trustfolio.

Pokeslide has made a place for itself by combining a genuine design standard with a responsiveness that many of its clients mention first in their reviews. With more than seven years in business, the Paris-based agency claims more than 500 clients and more than 2,500 projects delivered, for companies such as Bpifrance, BlaBlaCar, Suzuki, Servier, Lagardère, AXA, EDF, Sanofi, L’Oréal, KPMG, Deloitte or Heineken.

The scope covered is broad — event, financial and sales presentations, RFP responses, internal communications, templates, investor presentations and video presentations — with particular attention to respecting existing brand guidelines. It is a good choice for a marketing team that needs to produce quickly and often without sacrificing brand consistency.

Slideup is a studio founded in 2020, based in Bordeaux and Paris, that brings together about ten PowerPoint experts: creative directors, project managers, art directors and graphic designers. All production is done in-house, with no subcontracting abroad. The agency claims more than 1,000 clients, more than 5,000 presentations and 98% satisfaction, with references such as Clarins, TotalEnergies, Moët Hennessy, EDF, Shiseido or Chanel.

Its positioning is that of a full-service studio: editorial consulting, infographics, motion design, interactive presentations, templates and training. Stated budgets range from €2,000 to €8,000 excl. VAT for a 20- to 30-slide presentation with custom design, project management and light revisions included.

Praesens has made confidentiality its first selling point: “delegate the design of your presentations to experts, in full confidentiality.” For a finance department preparing results, a fund putting together a deal file or a team working on an unannounced operation, this is a criterion that comes before all others. The Paris-based, human-sized agency claims eight years of experience, about 90 companies supported and 150 presentations a year.

Its method follows four steps — discovery, art direction, design, delivery — and it stands out in formatting complex data, useful for financial presentations and CSR reports. Henkel, Onet, Toyota, L’Oréal, Lacoste, Montblanc or Pluxee are among its clients.

Effet Garanti isn’t a PowerPoint agency in the strict sense: it is a sales materials agency, founded in 2013, with 35 consultants, writers and designers. But that is precisely what makes it interesting for B2B sales teams. Its field is sales presentations, business reviews, proposals, product sheets and RFP responses — in other words, every document that has to help close the deal.

Its positioning rests on a simple idea: reconcile marketing and sales, by producing materials that salespeople are “proud to present” instead of redoing them on their own. The agency signs confidentiality agreements and counts Arval, Babilou, Fnac Darty or Porsche Consulting among its references. It is a subsidiary of Agence Nova, which specializes in B2B lead generation.

Spitch Consulting closes this ranking with a different profile: the Paris-based agency combines slide design with public speaking coaching. Its offering revolves around three activities — presentation consulting, a creative agency for designing materials, and Qualiopi-certified training programs in storytelling, public speaking, media training and soft skills.

It is a relevant choice when the deliverable is only half the problem: an executive keynote, a conference talk or an investor presentation depends as much on the speaker as on the slides. LVMH, L’Oréal, BNP Paribas, Aon France or the Four Seasons George V are among the references cited by the agency.
