The agency
A web, mobile and AI agency, run hands-on.
Bx Labs designs, builds and ships websites, mobile apps and AI-based systems. We are an independent agency based in Paris, and a studio that publishes software of its own. You talk to the person who designs and writes the code, from the first scoping call through to production.
What Bx Labs is
An agency, and a product studio.
Bx Labs is an independent web, mobile and AI agency. Independent means two precise things: nobody else owns the capital, and none of our recommendations is paid for by a vendor, a hosting provider or an ad network. When we propose a technology, it is because it solves your problem.
It is also a product studio: we publish our own software, held to the same production constraints as the projects we run for clients. That changes how we work for them. A studio that operates its own services knows the real cost of being on call, of a database migration, or of a dependency someone abandoned; it takes that into account while choosing, not afterwards.
We work with companies that have no in-house technical team, and with companies that do and want reinforcement on one specific piece of work. In both cases the rule is the same: what we deliver has to be able to live without us.
Transparency
Why we write “we”.
This site speaks in the first person plural because it is the company speaking, not someone in their own name. It is worth writing plainly: Bx Labs is currently run by one senior technical founder, alone. There is no sales department, no intermediate project manager, and no headcount to inflate in a deck.
That has concrete consequences: the number of engagements running in parallel is capped, answers come from someone who knows the code, and nothing is lost between the person who sells and the person who builds. In return, we turn down what we cannot honour.

What we do
Three services, one technical foundation.
The three services often combine on the same project: the site brings the enquiries in, the mobile app serves the repeated uses, and AI and business software absorb the manual work that is left. Each has its own page, with its own process and deliverables.
Service 01
Website & SEO
A fast site, findable in Google and in AI answer engines alike, plus business email that actually lands in the inbox.
See the serviceService 02
Mobile app
One codebase for iOS and Android, shipped to both stores and maintained well past launch day.
See the serviceService 03
AI agents & business software
Agents and business tools wired to your real data, integrated with your existing systems and supervised once in production.

How we work
Four stages, no six-month tunnel.
Scope
A call, your tools, what is costing you time. We write down what the project has to change and how we will know it worked: a success criterion set out in writing, not a general intention. It is also the moment we say whether a piece of work looks badly framed, or beyond us.
Design
Flows, content, data model and architecture, before the first line of interface code. Designing costs a few days; getting the foundations wrong costs the whole project. You sign off on that scope, and it is the reference for everything that follows.
Build
A first scope in production within weeks, wired to your real data — not a clickable mock-up. You follow progress on an environment you can reach, and you can react while a change is still cheap.
Operate
Release, measurement, fixes, changes. The system stays watched after go-live, because that is where the cases nobody anticipated show up. The source code is handed over in full, documentation included.
What we commit to
Five points, all of them checkable by you.
The source code is yours
Every line of code we write is handed over, in your repository, with installation and deployment instructions. Nothing is held back as leverage.
One contact, who designs and writes the code
The person who answers you is the person writing the software. No requirement degrades as it changes hands, and no promise is made by someone who will not have to keep it.
A reply within 24 hours
Every written request gets an answer within 24 working hours, in English or in French — including when that answer is “no” or “not now”.
A capped number of engagements in parallel
We turn work down rather than dilute it. That is the only way to honour the two commitments above instead of merely displaying them.
No sales intermediary
No commission, no licence resale, no partnership steering a recommendation. What we advise, we would have chosen for ourselves.
What we do not do
The list that makes the previous one credible.
A promise that depends on a search engine, a certification body or an app store is not ours to make: so we do not sell it. Here is what you will not find in our proposals.
We do not guarantee a first-page position
Nobody controls a search engine’s ranking, and whoever guarantees it is selling a result they do not control. We commit to the work: a technically sound site, pages that answer a real intent, and measurements you can read yourself.
We issue no certification and no compliance attestation
We apply the rules we know — accessibility, data protection, basic security — and we tell you where the project stands. An official audit, a label or an attestation is the business of accredited bodies, and we are not one.
We do not start a project without a written success criterion
A project whose success was never defined always ends in a disagreement about what should have been delivered. If we cannot write down together what has to change, we would rather not begin.
We do not sell a demo as a production system
A mock-up that survives ten minutes in front of a committee is not software: between the two lie the edge cases, error recovery, access rights, backups and monitoring. We always say which side of that line the thing in front of you sits on.
We do not build on a stack nobody could take over
We stay with widespread, documented technologies, so that another supplier or your own developers can pick the project up. A less common choice is sometimes justified: it is then explained, written down and owned, never merely inherited.
The products we publish
The studio, alongside client work.
Alongside client work, Bx Labs publishes software of its own. The first is a conversational agent for businesses, in preparation, with pilot access: it answers on the website, on messaging channels and on inbound calls, qualifies the request and hands over the right booking, quote or contact link.
The real state of each product — in production, or in preparation — is published as it is, rather than a page that would suggest it is available today.
Frequently asked questions
About the agency, not about the technology.
Are you an agency or a freelancer?
Bx Labs is a company, and the company is what contracts. It is currently run by one senior technical founder, alone: you get the commitment of a registered structure and the single point of contact of a freelancer. We write that down rather than let an agency page suggest a team.
Do you work remotely?
Yes, anywhere in France. Exchanges happen over video and in writing, with a written record after every significant decision; an on-site meeting is still possible when the subject warrants it. The quality of the follow-up does not depend on distance, it depends on what is written down.
What happens if we want to take development back in-house?
That is planned for from day one. The source code is handed over in full, with installation, deployment and operations documentation, and the accounts for the services used are in your name. We run the handover with whoever is taking it on, and we stay reachable for occasional questions afterwards.
How does an engagement start?
With an email describing your situation, the tool involved and the deadline that matters to you. We answer within 24 working hours, then we talk it through. If the project makes sense on both sides, you receive a written proposal: scope, success criterion, plan. Nothing starts before that document is agreed.
Tell us about your project
One email is enough to start.
Describe your situation in a few lines: what you want to put online, automate or take over, and the deadline that matters to you. We answer within 24 hours, in English or in French — including to say it is not for us, and to point you elsewhere.
