Kleio Raises €3M to Expand AI-Powered Conversational Agents

Kleio, a multi-agent generative AI platform specializing in conversational agents, has secured €3 million in seed funding to enhance adoption, expand AI capabilities, and refine sales-focused AI models.
Founded in 2024, Kleio helps businesses optimize B2C purchasing journeys with AI-driven conversational tools. The company has collaborated with travel brands like Havas Voyages, Comptoir des Voyages, and Showroomprivé to improve customer engagement and sales conversions.
The funding round was led by Serena and Daphni, with additional backing from industry leaders including Houman Behzadi (C3 AI), Julien Bellanger (Prevoty), Raphael Simon (formerly Shine.fr), and Dave Kellogg (formerly HostAnalytics and Salesforce).
“Our goal is to empower enterprises with an AI platform that delivers personalized, data-driven buying experiences, outperforming traditional in-store interactions,” said Philippe Wellens, Kleio’s co-founder and CEO. He emphasized the company’s commitment to improving brand engagement and driving measurable sales growth.
Beyond customer engagement, Kleio’s AI platform supports sales teams through lead nurturing, qualification, scoring, and workflow automation. The company’s conversational AI enhances product recommendations, streamlines customer service, and enables intelligent routing for more efficient sales processes.
Havas Voyages, one of Kleio’s early adopters, reported a 200% increase in web leads, thousands of sales conversations, and significant lead generation within three months of implementation.
Looking ahead, Kleio plans to expand its AI solutions beyond travel, targeting industries like real estate, energy, cosmetics, and financial services to deliver AI-powered customer interactions with a personalized touch.
