AI Development Company in Paris
The best AI Development Company in Paris, at the best available price.
Most of what gets sold here as AI development is a team of five with one person who has shipped, and a bill that reflects the other four. This is the opposite arrangement: the engineer who scopes it is the engineer who builds it, the price is fixed before anything starts, and you pay nothing until a checkpoint is delivered and you accept it.
Paris has become one of Europe's main centres for AI research and AI startups, alongside a large base of corporate headquarters in luxury, retail, banking, insurance and energy. Large French groups buy through formal procurement and expect suppliers to meet French and EU requirements on data protection and hosting. The startup scene around Station F moves faster but often sells to those same groups.
AI work in Paris covers customer service in French and other languages, retrieval over contracts and internal documents, and content tools for retail and luxury. Each system is built with evaluation and a written description of the data used, which helps with CNIL guidance and CSE consultation.
What you get
- One senior engineer end to end: the person on your first call architects it, writes it and hands it over
- LLM features, retrieval over your own documents, agents that call real tools, and voice where it earns its place
- Deployed in your own cloud account in a regional data centre, or on your own hardware where residency demands it
- Fixed price and fixed scope agreed in writing before work starts, invoiced per accepted checkpoint
- Code and infrastructure in your repository and your accounts, written to make us replaceable on purpose
Nothing payable upfront. You hold every dollar until a checkpoint is delivered and accepted, and thirty days of defect correction is included. Final scope and price are settled on a call before any work begins.
Invoiced in USD or EUR, payable by Wise or bank transfer.

Who builds here
AI Development Company
Paris has a deep market for AI product work, and French buyers expect it to come with the CNIL-aligned documentation, hosting choices and works council preparation that local rules require.
What Paris companies build with us
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Twenty-minute call
You talk to the engineer who will build it. We scope the problem, and if this is the wrong fit for you, you get told so on that call rather than three weeks into a proposal.
Fixed proposal in 48 hours
Fixed price, fixed timeline, defined deliverables, in writing. No hourly billing, no open-ended scope, and no change-request business model.
Checkpoints until it ships
Working software at each checkpoint, with acceptance criteria agreed before that checkpoint starts and an invoice only after you accept it. Direct access throughout, not a ticket queue.
What actually applies here.
Regulation and data
GDPR applies with France's Loi Informatique et Libertés, and the CNIL has published detailed practical recommendations on applying GDPR to the development of AI systems, including when legitimate interest can justify training. Hosting health data requires a provider certified under the HDS scheme, and sensitive public-sector data is increasingly expected to sit on cloud services qualified by ANSSI under SecNumCloud. Banks and insurers are supervised by the ACPR and have applied DORA since January 2025. French courts have suspended AI deployments until the works council (CSE) was consulted under Article L2312-8 of the Labour Code. France's NIS2 transposition bill was still before Parliament at the time of writing. The EU AI Act has been in force since August 2024: general-purpose model rules applied from August 2025 and transparency duties from August 2026, while the 2026 Digital Omnibus moved the main high-risk obligations to December 2027 for stand-alone systems such as hiring or credit scoring, and August 2028 for AI built into regulated products.
Contracting and payment
You contract with an individual consultant based in India. Invoices in EUR or USD, paid by Wise or bank transfer. Your accountant handles an overseas supplier in the usual way, and any documentation they need is provided before access is granted.
Working hours
Four or more hours of daily overlap across your morning, Central European time, with same-day replies on working days.
Can you prepare documentation for a CSE consultation?
Yes, on the technical side. We describe what the AI tool does, what data it uses, what it logs and how people stay in control of its outputs. The consultation itself is run by you with your CSE, and we can adjust the deployment to what is agreed.
Do you work in French?
The work, code and documentation are in English. AI systems we build can handle French and other languages for your users, and the technical documentation is written clearly enough for your team to adapt for French-language stakeholders.
How do working hours line up with Paris?
Four or more hours of daily overlap across your morning, Central European time, with same-day replies on working days. The work is remote from India, so meetings happen on calls rather than in person.
Why would we use an overseas engineer rather than a local integrator?
Often you should use both. An integrator holding the prime contract and the local relationship, with a specialist doing the AI and data layer underneath, is a common and sensible structure here. What you should not do is pay integrator rates for engineering that one person is actually doing.
Can the system run entirely inside our own infrastructure?
Yes, and in this region that is frequently the requirement rather than the preference. Model serving on your own hardware or in your own cloud account in a regional data centre, with no outbound calls, up to fully air-gapped.
Who owns the code?
You do, entirely. It ships into your repository on your own cloud accounts, documented so your team or your next hire can carry it without us, and all our access is removed at handover with written confirmation.
