Clusterlab: The Tunisian Startup That Made It to Y Combinator
A Milestone for the Tunisian Ecosystem
With over 27,000 applications and only 150-200 spots available, the odds were against them. But Clusterlab, a Tunisian startup specializing in artificial intelligence, has made it to the prestigious Y Combinator program, joining the X26 batch. This achievement is a testament to the potential of the Tunisian ecosystem and a victory for the entire community.
Less Than 1% Chance of Success
To put this achievement into perspective, Y Combinator is one of the most selective and prestigious acceleration programs in the world. Founded in 2005 in San Francisco, it has incubated successful companies like Airbnb, Stripe, Dropbox, DoorDash, and OpenAI. With over 4,500 startups accompanied and a cumulative valuation exceeding $600 billion, the program's admission rate is around 1%. Clusterlab's admission is a remarkable feat, and CEO Haithem Kchaou is proud to represent the Tunisian ecosystem.
More Than Just a Training Program
Y Combinator is not just a training program; it's the heart of the Silicon Valley ecosystem. The selected startups gain direct access to the network of CEOs and program directors, some of whom are now leading the world's largest tech companies. The program's culmination is the Demo Day, where each startup pitches to hundreds of top-tier investors. This is a gateway to the best of what the world has to offer.
A Three-Month Program with Exceptional Opportunities
The program spans three months and includes sessions with exceptional speakers, one-on-one meetings with YC partners, and founders who have built and sold companies with significant valuations. The highlight of the program is the Demo Day, where each startup presents its project to an international audience of investors.
Callab.ai: The AI-Powered Vocal Platform
What convinced Y Combinator is Callab.ai, developed since 2025. This AI-powered vocal platform is designed for call centers, enabling virtual agents to respond, qualify, and process customer calls 24/7 without interruption. According to Haithem Kchaou, "The contact center sector is still largely unautomated. Existing solutions don't scale well in certain markets, but we've made it work."
A Cutting-Edge Technology with Global Ambitions
What sets Callab.ai apart is its cutting-edge technology, which is innovative, sophisticated, and complex to develop. This approach has allowed Clusterlab to sign with major contact center operators in Dubai, France, and the United States. The platform supports multiple languages and was designed for global expansion from the outset.
Tunisian Roots and Solid Financing
Behind Clusterlab are two founders educated in Tunisian universities: Haithem Kchaou (CEO) and Chehir Dhaouadi (CTO). The startup has benefited from the Startup Act label and was accompanied in its early years by Réseau Entreprendre Tunisie and The Dot. Today, it is registered at the Abu Dhabi Global Market (ADGM). On the financial side, Clusterlab has attracted reputable investors, including Karim Beguir, CEO and co-founder of InstaDeep, acquired by BioNTech for $680 million. YC has also invested in Clusterlab upon admission, even before the program's official start.
