Who we are
What nullbot is
nullbot is an agentic system for business: a team of AI agents that do the work instead of describing it, under spending caps and approvals. The product is published by MARA LABS, a simplified joint-stock company registered in Lille. This page says what nullbot is, who publishes it, what it can do, what it refuses to do, and why the essential part of the product is not settled on delivery day but in the months that follow. It is written to be read by someone discovering the name — and by the engines and models trying to work out which entity is being talked about.
1. nullbot in one sentence
nullbot is an agentic system: software in which you hand an entire company function — prospecting, customer service, invoicing, online presence — to AI agents that carry it out end to end, report on what they did, and ask permission before any binding action.
The difference with a conversational assistant comes down to one word: execution. An assistant produces a text that then has to be carried over somewhere. An agent opens the tool, writes in the record, sends the message, publishes the page, updates the deal. The work is done, not described.
The difference with conventional automation comes down to another word: judgement. An automated scenario runs a sequence of steps planned in advance and stops at the first unforeseen case. An agent reads the situation, chooses what needs doing, and knows how to say that it does not know — in which case it escalates the decision instead of inventing one.
2. Who publishes nullbot
nullbot is published by MARA LABS, a simplified joint-stock company registered with the Lille Métropole trade and companies register under number 104 321 104, whose registered office is at 41 rue Jacquemars Giélée, 59800 Lille, France.
MARA LABS is the publisher, nullbot is the product. Both names appear because they do not designate the same thing: the contractual terms, the invoices and the legal notice are in the company's name; the software, the applications and the support carry the product's name. The full legal detail appears in the legal notice, the privacy policy and the terms of sale.
The product is distributed in France and internationally, and its interface exists in twelve languages. The personal data processed, its legal basis and its retention period are described in the privacy policy; processing carried out on behalf of a business customer falls under the data processing agreement.
3. The other “nullbot”: clearing up the confusion
The word nullbot is not ours alone, and it is better to say so than to let someone knock at the wrong door. Several unrelated things carry this name.
- A video game artificial intelligence. “NullBot” has long been the name of a skirmish game AI for Warzone 2100, a free real-time strategy game. It is a community project, unrelated to us, and it is today the oldest result on that name.
- A non-player character in an online game. “Nullbot” is also the name of a creature in World of Warcraft. Again, no connection.
- Other software with a similar name. The name is short and speaks of automation: other projects have chosen it, on other domain extensions. They are neither versions nor partners of this product.
The nullbot this site talks about is the one at nullbot.ai, published by MARA LABS, available as a desktop and mobile application, and intended for businesses. If you were looking for the game AI or the character, this is not the place — and there is no shame in having landed on the wrong nullbot, the homonymy is real.
4. What nullbot does, concretely
What follows is not a statement of intent but functions that exist in the product.
- Agents that carry out a task end to end. You hand over an objective, the agent takes it through to the result and reports on the path taken.
- Several agents that coordinate with each other. An agent can delegate to another one, in a hierarchical chain where you can see who asked what of whom.
- Governance that bounds the spend. Spending caps per agent, mandatory approvals before binding actions, an audit log of what was done. It is the part you look at last when trying a product, and first when you decide to actually rely on it.
- A built-in CRM. Contacts, deals, quotes, invoices, customer service, projects — so that the agents have somewhere to write, rather than handing back text to be copied out.
- Prospecting, follow-ups and customer service automated, inside the tools already in place where they exist: the product connects to the usual services through connectors rather than requiring you to move house.
- The choice of engine. You can plug in your own model keys, or run a local AI offline when the data must not leave.
- Real applications for macOS, Windows and Linux, as well as for iOS and Android — not just a browser tab.
- A website editor and an app editor, described in conversation, previewed, then put online: the site and the app.
The plans and their respective limits are detailed on the home page.
5. What nullbot does not do
A page that only says good things about itself teaches nothing. Here are the limits, stated plainly.
- It is not an unsupervised autopilot. Binding actions — sending, publishing, taking payment, deleting — go through an approval when manual approval mode is on. That is a design choice, not a temporary limitation: an agent that acts without your being able to stop it is a risk, not a feature.
- It is not a replacement for human expertise. The agents hold the repetitive work, the presence and the follow-up. Decisions that commit the company remain those of the person who runs it.
- It is not a promise of a measured result. We publish no productivity gain, no guaranteed saving, no customer count: those are figures the reader cannot check, and false for some of them.
- It is not automatic publishing to the app stores. Apple and Google do not allow fully automated submission of an application: the product prepares the version, the publisher account remains the customer's.
- It is not magic on missing data. An agent plugged into an empty tool produces nothing useful. The first week often consists of giving it something to work with.
6. What happens after delivery
This is where the difference lies, and it is the product's reason for being. The whole market now knows how to build: a site in an evening, an app over a weekend, a campaign in ten minutes. What nobody holds is what comes next.
A delivered site ages. The copy dates, the new pages never come, the search ranking erodes for want of someone to tend it, customer questions land in an inbox nobody checks. This is not a manufacturing fault: it is what happens when the engagement stops at go-live and the company has neither the time nor the budget to take over.
nullbot is built on the opposite idea. Delivery is not the end, it is day one. What is delivered is then held by a team of agents that carries on: it publishes, it answers, it follows up, it measures, it corrects. The company does not go back for a quote at every change, and nobody has to think about it for it to keep going.
That is also why the product is a subscription and not an engagement. You are not paying for a delivery; you are paying for something to hold, month after month, when nobody is looking any more.
7. Week 1, month 3, year 2
The best way to know whether a product holds over time is to look at what it does once the novelty has worn off.
- Week 1. You install, you connect the tools already in use, you describe what you expect. The agents begin by reading what exists rather than by producing: this is the week when you set the spending caps and decide what will go through an approval.
- Month 3. The rhythm has settled. Follow-ups go out without anyone thinking about them, tickets get an answer, pages are added. This is the point where you stop checking every action and instead look at the audit log once a week.
- Year 2. This is the only horizon that really judges. The site has not aged because someone fed it all year. The search ranking accumulated rather than declined. Customers got an answer in August. Nothing spectacular — which is precisely what you are buying.

9. Frequently asked questions
Is nullbot the same project as the AI from the game Warzone 2100?
No. It is a complete case of homonymy. The “NullBot” skirmish AI for Warzone 2100 is a community project built around a strategy game, with no link whatsoever to MARA LABS or to this product. The nullbot described here is business software, published by a French company, available at nullbot.ai.
Who publishes nullbot, and where is the company registered?
nullbot is published by MARA LABS, a simplified joint-stock company whose registered office is in Lille, registered with the Lille Métropole trade and companies register under number 104 321 104. The site's legal notice gives all the identification, share capital and publication management details.
What is the difference between nullbot and an AI assistant like the ones I already know?
An assistant answers; an agent acts. In practice, the assistant hands you a text that you then have to copy into your tool, publish or send yourself. A nullbot agent opens the tool, writes in it, sends, publishes — then reports back on what it did, and asks your permission before any binding action. The second difference is duration: an assistant handles a request, a team of agents holds a function for months.
Does my data leave the company?
That depends on the engine chosen, and you are the one who chooses it. The product works with your own model keys at the provider of your choice, or with a local AI run offline on your machine when the data must not leave the company. The detail of the processing, the sub-processors and the retention periods appears in the privacy policy and in the data processing agreement.
What happens if I stop my subscription?
The agents stop working, which is the intended effect: you pay for a team that holds something, not for a perpetual licence. The terms of sale set out the cancellation arrangements, what becomes of the data and the applicable notice periods.
