Best AI agencies in Paris in 2027: a verified comparison

This comparison is published by Lumyniq, an agency based in Paris that is on the list. To limit that bias, every agency was checked against the same criteria on 10 November 2026:

• Presence in Paris, checked in the French national business registry: an active head office or establishment inside Paris. An “AI agency Paris” page is not enough. For Poller, the match with the registry rests on the name alone, as the site publishes no company number.
• Legal entity: legal form, founding date and headcount band in the registry, compared with the legal notice on the site.
• Pricing, taken only from the agency's own site. Where none is published, the comparison says so.
• Reviews, taken from Trustpilot. Google or Malt ratings are only quoted “as shown by the agency”.
• Certifications: Qualiopi checked in the public DGEFP list; other claimed statuses are flagged as self-declared when they could not be verified.

This is a snapshot. Sites change, sometimes within weeks, so repeat these checks before you sign. Our comparison of AI automation agencies across France applies the same method nationally.

• Lumyniq: Custom AI agents, automation, websites and SaaS, with expertise in regulated sectors (real estate, legal, healthcare, HR).
• Galadrim: Building a business application or an AI agent with a large development team.
• Koïno: Putting together a team of AI and data experts on demand, from scoping to prototype.
• Stema Partners: Training teams and scoping an AI assessment, with a B2B prospecting service.
• Gensai: A first agent, chatbot or voice agent at a published price, hosted in France.
• Poller: Classic data science (forecasting, optimisation) alongside agents and chatbots.
• Sociaty: AI training for marketing, sales and communications teams.
• Flowt: Combining business intelligence and generative AI in the same project.
• Mozza: Designing a consumer-facing digital product with AI at its core.
• Impulse Lab: Replacing spreadsheets with business software that has agents built in.

These firms show up in search results for “AI agency Paris”. Each was left out for a verifiable reason, with no judgement on the quality of its work.

• Juwa: Head office in Villeneuve-d'Ascq and no Paris establishment in the registry, despite offices announced on its site. Juwa appears in our France-wide comparison.
• Nocode Factory: Published by Baleine Verte, head office in Bobigny, no Paris establishment in the registry. Also in the France-wide comparison.
• Devflows: Head office in Boulogne-Billancourt according to the registry, while its legal notice says Neuilly-sur-Seine. Outside Paris either way.
• Masteria: Head office in Lyon. The site has an "AI agency Paris" page, with no Paris establishment in the registry.
• Insign: Head office in Lyon, no Paris establishment in the registry.
• GENIAL: A brand of the company Cibler, head office in Mérignac, no Paris establishment in the registry.
• Digitallia: Its legal notice link is dead, and the addresses on the site (Paris 10th, Haguenau) do not appear in the registry, which ties the name to a sole trader in the 12th. The link between the site and a legal entity could not be established.
• IA Agency (ia.agency): Site returning a 502 error on 10 November 2026, no identifiable entity.
• Sortlist, La Fabrique du Net: Directories and marketplaces, not agencies.

Large data and AI consultancies, which work mainly for large groups, and software vendors were not included either.

Paris concentrates demand, and so the pages written to capture it. These checks apply to any agency, ours included.

• An “AI agency Paris” page with no establishment in Paris. Several agencies publish the same page for every city: twelve cities at Flowt, four at Poller, a series at Sociaty. Only the registry says where a company is actually based. Open its list of establishments.
• A missing or incomplete legal notice. French law requires at least the company name, address and registration number. On 10 November 2026, Poller showed neither a SIREN nor an address, and Mozza and Impulse Lab had no legal notice page: their identity appeared only in the privacy policy.
• An address that does not match the registry. Koïno's footer gives a closed establishment; Devflows shows Neuilly-sur-Seine where the registry says Boulogne-Billancourt. It is a gap worth asking about before you sign.
• Percentages with no source. “99% measurable ROI”, “95% of proofs of concept scaled”: with no method or sample, these figures cannot be checked. Ask for a named client who agrees to talk.
• Rankings published by the agencies being ranked. Koïno and Juwa each publish their own “top 10” of Paris AI agencies. This comparison is also published by an agency on the list: judge it on the verifiable facts.
• Paid recommendations. Impulse Lab pays for client referrals. When someone recommends an agency to you, ask whether they earn a commission.
• Public funding described wrongly. Bpifrance publishes a 40% grant for its Diag Data IA; one agency in this comparison states 25%. Always check the terms on the Bpifrance site.

Of the nine Paris agencies checked, only one publishes a price for building an agent and putting it into production. The other published prices mostly cover training and audits.

For a French SMB, the first line to look at is often the assessment. According to Bpifrance, the Diag Data IA covers 8 days of work over 3 months, with the quote capped at €10,000 excl. VAT and €6,000 excl. VAT left to pay after a 40% grant. It is open to independent SMBs and mid-sized firms with 10 to 2,000 FTEs, at least €1 million in revenue and more than a year of existence. Development afterwards is budgeted separately; our guide to funding an AI project as a French SME covers the other schemes.

The price of a project depends mostly on how many tools need connecting, the quality of the starting data and how demanding the compliance requirements are. Monthly model usage and maintenance always come on top of setup: have them priced in the first quote.

Four questions separate these agencies:

• Do you want a product or an automated process? An application, a website or a SaaS product needs a team that writes code: Lumyniq, Galadrim, Mozza and Impulse Lab all build them. An agent that handles requests or documents inside your existing tools needs an AI agency, which Lumyniq also is. To frame that need, our custom AI agents page describes what an agent can take on.
• Is your data sensitive? Health, legal, customer or candidate data: ask where the data is hosted and who can access it. The obligations are set out in our guide to the AI Act for businesses.
• Are your teams ready? If nobody uses AI yet, training funded through an OPCO with a Qualiopi-certified provider (Stema Partners, Sociaty, Flowt, Galadrim) can come before the project.
• Who maintains the tool after delivery? A workflow breaks when a connected tool changes. Require that code, workflows and access stay on your own accounts. If you work with n8n, our n8n agency page explains what to ask for.

Constraints vary a lot from one industry to another. Our sector guides cover them for real estate, law firms, healthcare and human resources.
