No fundraising, no marketing department, no outsourced support 8,000 km away. Just two reachable founders building a tool they use themselves.
It was born from a concrete customer need, a market observation, and a bet between two Savoy and Lyon.
2024 · The turning point
It all starts with a French customer, overwhelmed with phone calls, who asks a simple question to Mathias Is there a solution to automatically qualify prospects in French without hiring? The tools on the market at the time were either American and poorly translated, or based on rigid scenarios incapable of understanding a real question.
Mathias built a first custom chatbot for this client. The result: natural conversations, effortlessly qualified leads, and a second chatbot was ordered immediately. The first sign: there's a real demand for an assistant that speaks genuine French, is connected to a real catalog, and isn't just a scripted robot.
2025 · The Two-Person Bet
Mathias calls Nicolas Buathier, Nicolas, a developer from Lyon whom I met a few years earlier through a mutual friend, tests AI models as soon as they are released, is a fan of SaaS projects, and works with a reassuring rigor. The idea quickly evolves: what if we transformed what worked as a customized solution into a real self-service product, accessible to any entrepreneur?
For months, Nicolas redesigned the entire technical architecture. Mathias structured the offering, pricing, and positioning. The objective: that any entrepreneur, freelancer or SME can create their AI chatbot in 5 minutes, without a developer, without hidden costs, and in French that doesn't sound like a bad translation.
April 2026 · The launch
CauserieBot officially launches as a self-service tool at causeriebot.com. Three transparent subscription plans (Free, €49/month, €99/month). Six AI models to choose from (GPT-4o, Claude, Gemini). Installation requires only one line of code. And one clear objective: to become the leading French-language AI chatbot provider, without raising money or hiring..
Today, the product improves every week, fueled by direct feedback from early adopters. Mathias works from Savoie, Nicolas from Lyon. When you write to hello@causeriebot.com, It's one of us who answers. Not a bot. Not an offshore agent. Not a 5-day delay.
Mathias manages strategy, marketing, and customer relations. Nicolas manages technology, AI, and infrastructure. No unnecessary meetings, no steering committees: we build, we deliver, we iterate.
An entrepreneur since the age of 22, Mathias has built his career alongside several ventures. He leads the marketing, SEO/AEO, business development and CauserieBot's customer relations. His conviction: a good product sells through its clarity, not its advertising budget.

He is responsible for technical architecture, model integration (GPT-4o, Claude, Gemini), GDPR infrastructure and product stability. Its hallmark: deliver quickly, test in production, correct even faster.
