Custom business software, web application and AI agent development

Novane is a French software development agency based in Paris. Our core business: custom business software and ERP/CRM, web applications and SaaS, and artificial intelligence solutions (AI agents, AI assistants connected to your data, workflow automation). We also support our clients with acquisition (SEO, GEO, SEA, sales and prospecting strategy), cybersecurity, cloud and DevOps, IT consulting, training and staff augmentation.

An off-the-shelf tool forces you to adapt your processes to its limits, with per-user subscriptions that add up. Custom business software matches exactly how you work, centralizes your data, eliminates duplicate data entry and connects to your existing tools. It makes sense as soon as your teams waste time in spreadsheets, juggle several tools, or your business has specifics no standard tool covers. During the discovery call, we assess with you whether an existing tool could be enough.

Our projects start from €1,800 excl. VAT per week of development, depending on the project. The total budget depends on the functional scope: we define it with you and provide a free, detailed quote before anything starts. Payment is weekly, as the project progresses, so you stay in control of your budget. You can also get a first estimate with our online simulator.

It depends on the project. As a guide: a V1 AI agent or a showcase website can be up and running in as little as 1 week, a V1 web application, SaaS or e-commerce website in as little as 2 weeks, and a V1 business software or ERP/CRM in as little as 3 weeks. Since we bill weekly, a tighter scope also means a lighter budget. The detailed schedule is set from the discovery call.

An AI agent is a program that understands a request, reasons and takes actions in your tools, whereas a classic chatbot only answers. For example: qualifying leads and updating your CRM, preparing quotes or follow-ups, sorting and handling emails, extracting data from invoices or contracts, tracking tasks and reminding the right people. We connect it to your tools and define with you what it can do on its own and what requires human approval.

Yes. We design each AI solution to match your requirements: models hosted in Europe, or sovereign AI deployed on-premise on your own servers so your data never leaves your infrastructure. Access is restricted according to your users' roles.

Yes. Our AI agents and assistants connect to your current tools (CRM, ERP, email, calendar, Slack, Drive, databases, support tools) without forcing you to change how you work. We can also integrate AI directly into existing software or SaaS.

Yes. We work on your visibility on Google (SEO, SEA) and in AI answer engines such as ChatGPT, Perplexity or Google AI Overviews (GEO). We also advise you on your acquisition and prospecting strategy: positioning, go-to-market, CRM setup and prospecting automation. The goal: making sure your software or offer finds its customers.

We build security into the development of your applications (DevSecOps). We also perform Active Directory and Entra ID audits, harden your servers and set up backups to protect your business against data loss.

Everything starts with a free discovery call to understand your needs. We then work in one-week sprints: each week, we define together the features to build, you follow progress on a test environment, and a weekly check-in brings you together with the developer and the project manager. Communication happens on a dedicated Slack or Discord channel.

Technical support is included free of charge for 2 months after go-live: bug fixes, minor adjustments and onboarding help. We train your teams on the delivered tool. After that, we offer maintenance and evolution plans on a quote basis.

Yes: a 7-day money-back guarantee from the start of the engagement. It covers Novane's fees for the first week, excluding third-party costs (domain name, licenses, hosting). If you are not convinced, a simple email is enough to activate it, and the refund is made within 24 business hours.
