Kleio, an Enterprise Conversational AI startup, has secured seed funding to accelerate its AI-driven platform for streamlining complex sales processes, enhancing customer engagement, and improving conversion rates.
Kleio, a rising innovator in Enterprise Conversational AI, has raised €3M in seed funding to accelerate the adoption of its AI-driven platform. The round, led by Serena and Daphni, will fuel Kleio’s mission to redefine how enterprises engage with customers—particularly in industries where sales processes are complex and require a high-touch approach.
For companies in sectors like real estate, automotive, energy, financial services, and travel, the customer journey is often lengthy and intricate. Kleio’s AI-powered platform simplifies this experience by streamlining interactions, automating lead qualification, and improving conversion rates. Early adopters, including Showroomprivé, Havas Voyages, and Effy, are already seeing significant results, with Havas Voyages reporting a 200% increase in web leads in just three months.
Conversational AI expertise at the helm of Kleio
Founded in early 2024, Kleio is led by AI veterans Philippe Wellens, Adrien Mathieu, and Louis Poirier, who bring over 30 years of combined experience across AI product development, sales, and technology. The founding team previously held key positions at C3 AI in both Europe and the US, shaping AI-driven enterprise solutions at a global scale.
Their expertise has been instrumental in designing Kleio’s next-generation Conversational AI, which moves beyond traditional chatbot models. Unlike generic AI tools that repurpose legacy chat systems, Kleio’s technology is purpose-built to handle the nuances of complex sales conversations.
A next-generation Conversational AI platform for high-value sales
Kleio’s system is powered by a network of over 30 AI agents, each specialising in different aspects of the sales process, from personalised product recommendations to intelligent lead prioritisation and automated sales workflows.
The platform’s proprietary knowledge engine combines advanced data technologies—including graphs, semantics, and structured databases—to help businesses leverage their data more effectively. This ensures that customers receive tailored, data-driven responses that enhance engagement and drive sales conversions.
“We have been captivated by Kleio’s vision to redefine customer experience with Conversational AI,” said David Dayan, CEO of Showroomprivé.com. “Their platform unlocks new possibilities for elevated customer experiences with hyper-personalisation, and significant sales growth for Showroomprivé,” added Nicolas Gerbal, Director Travel & Leisure at Showroomprivé.com.
Strong backing from enterprise software leaders
Kleio’s €3M seed round attracted support from some of the industry’s most experienced investors. Alongside lead investors Serena and Daphni, the round included participation from prominent enterprise software leaders such as Houman Behzadi (Executive VP at C3 AI), Julien Bellanger (CEO at Prevoty), Raphael Simon (ex-CTO at Shine.fr), and Dave Kellogg (ex-CEO of HostAnalytics & ex-SVP at Salesforce).
These investors bring deep sector expertise and a track record of scaling enterprise software companies, reinforcing confidence in Kleio’s potential to reshape Conversational AI for businesses.
Scaling AI capabilities and global expansion in 2025
With fresh funding in hand, Kleio plans to expand its AI capabilities by increasing the number and specialisation of its AI agents, enhancing platform integrations with enterprise systems, and training benchmark-leading AI models tailored for sales-driven industries.
“Our goal is to provide enterprises with an AI platform to create tailored, intuitive, data-driven buying experiences that outperform in-store interactions,” said Philippe Wellens, Co-Founder and CEO of Kleio. “We position ourselves as long-term partners, continuously enhancing customer experiences for brands and delivering measurable boosts in sales results. We’re also technological partners for other sales-related use cases such as augmentation of internal sales teams, lead nurturing, and lead scoring.”
To support its growth, Kleio will scale its engineering, sales, and marketing teams throughout 2025, positioning itself as a key player in the rapidly evolving Conversational AI landscape.
Kleio provides a Multi-Agent Generative AI platform to design, deploy, and monitor intelligent conversational agents. Kleio’s AI-driven technology revolutionises customer interactions by enabling natural, concise, and friendly communication that enhances engagement and boosts conversions.
