The starting point
Osmosia was born from an observation, that of Pierre Osmont, after fifteen years spent making data talk for companies.
When a car seller closes their dealership and heads home, their prospects do the same. Except that this is precisely when, in the evening, at the weekend, once the day is over, private buyers are most active in their search for a vehicle. The enquiries come in when no one is available to answer them anymore.
“ The seller goes home, the buyer really starts searching. The two are almost never available at the same time, and that is where the sale is won or lost. ”
Pierre Osmont
Teams are overloaded, at peak activity, or simply away. Some messages go unanswered, or get a reply too late to matter. The prospect, meanwhile, does not wait. They buy elsewhere.
01 Pierre Osmont
Fifteen years making data talk
Pierre Osmont made data his craft, never as an end in itself. Since 2010, he has worked it to draw out value and put it to work for the business, strategy and growth, steering companies toward a data-driven approach.
Trained at the IUT of Vannes in statistics and decision-support computing, he started at the Française des Jeux, then spent six years at Viadeo turning figures into decisions: segmentation, targeting, performance measurement. At Ogury, he worked daily with more than a hundred terabytes of behavioural data.
In 2018, he joined leboncoin. For seven years, as Data Ad Manager, he worked at the centre of France's largest classifieds platform, where buyers and sellers meet, where a contact becomes a sale or is lost. It is from this vantage point that he draws his conviction: response speed decides the sale, often before price or pitch.
From this path he keeps a double hat, data and business, and a clear view of what he still lacked: the codes of the field and the concrete mechanics of automotive sales. In July 2025, he left leboncoin to found Osmosia.
“ For seven years, I watched thousands of contacts turn into sales, or vanish. The difference often came down to a single thing: response time. ”

02 Thomas Forget
The engineer who chose sales
An engineer, a 2013 graduate of the Icam, Thomas Forget quickly took a less expected direction: commercial performance. At Quaternaire, a consulting firm, he spent five years supporting more than twenty leaders of mid-market and large industrial companies in improving their results.
In 2019, he joined the software company 3P as Sales Director for France. For six years, he sold SaaS to demanding professionals and structured growth: recurring revenue was multiplied sixfold, and he led a team of six sales engineers. There he learned what cannot be improvised, how to carry software all the way to professional clients and sustain growth over time.
In late 2025, he left 3P to start a venture.
“ I spent years equipping sales teams. Osmosia does the same thing, but for every lead, seven days a week. ”

03 The meeting
In early 2026, in the Nantes tech ecosystem, two ambitions crossed paths. Pierre had left leboncoin, Thomas had left 3P, both determined to build something. What first brought them together was not a shared profession, but the drive to build and the chance to help each other on their respective projects.
Pierre had launched Osmosia. What he lacked was exactly what Thomas knew how to do: bring software to professionals and structure a sale. From that mutual helping hand grew a complementarity that has never stopped working. Thomas joined the project as associate director.
04 The vision
Osmosia starts from a simple principle: artificial intelligence is not there to replace the seller, but to give back what they lack, time and genuinely hot contacts. By answering every request without letting it wait, qualifying prospects and organising appointments, Osmosia lets sellers focus on what no machine will do in their place: closing.
