| Ordalie AI | Ordalie is a generative AI dedicated to the law: a “ChatGPT" of the law.It's a project that aims to drastically reduce the time spent by legal professionals and managers (SMEs) on legal research and contract drafting.To achieve this, we have developed our own specialized AI models that are directly connected in real time to all legalsources. We automate legal work through multiple instances of autonomous, workload-balanced AI agents, working at scale at human-level precision.Ordalie was born out of the realization that legal information is disparate and unintelligible, which can lead to a considerable loss of time in researching it and returning it to the customer. When I worked in a law firm, 60% of my time was spent doing legal research and then trying to articulate all the information I'd gathered to extract a clear, structured response for the client. AI meets this need to optimize the time spent on legal research and drafting.At this stage, we are initially co-developing our product with several of the most prestigious partner law firms, to ensure that the reliability of our legal answers is in line with the standards of the most advanced and experienced legal professionals.But as our ambition is to provide easier access to and better understanding of the law, we are not only targeting legal professionals, but also the managers of very small businesses who face legal issues on a daily basis. The idea is to help the manager of a small structure who would not be financially able to hire a full-time legal expert or seek the advice of a lawyer as frequently as he or she would like. Today, the legaltech market focuses exclusively on legal professionals. However, our AI adapts to all levels of understanding and requirements without having to reinvent the product for each target, which means that legal knowledge is not just for lawyers.So we're positioning ourselves as a B2B SaaS model with two offerings. • A €69/user/month subscription (beta launch price); • An API offer (billed by volume) already in place with several partners, enabling them to implement our technology on their interface for the benefit of their customers. | $2M | Seed | Jun 03, 2025 | https://ordalie.ai/ |
